“Ready, fire, aim.”
“If you don’t know where you’re going, any road will get you there.”
“Shoot from the hip.”
These are not sayings you want to hear when you’re trying to set direction and plan for operational performance improvements. Yet, this is often how situations are described in hindsight when the vital first steps are done poorly. Not to mention those situations where months and months (and MONTHS) of deep dive analysis result in a pretty presentation but isn’t rooted in any kind of operational reality and shortly thereafter, falls flat on its face. (Sound familiar anyone? Bueller? Bueller?)
To develop an improvement plan and portfolio you must first get an accurate baseline of the current situation and describe the gaps. Doing this part well ensures better results because you’ll have practical, and more importantly, credible, information starting out.
In this post, we outline 5 critical factors that we use to ensure a high quality, yet efficient performance evaluation process. One that leverages internal experts and external viewpoints, is focused on both the operational realities of the front line and leadership priorities / objectives, and that gives everyone the same baseline measurement system from which to make an objective assessment of “what good looks like.” This process can take as little as a couple of days. Check out Kaufman Global’s Rapid Performance Evaluation.
But, before we dive into the 5 factors, a short history of business consulting analysis…
For many years, the traditional way of getting started with clients involved a request for lots of data, a long list of questions and a team of four or five consultants onsite for 4-6 weeks to conduct a formal analysis. This would result in an implementation road map and ROI calculation that validated the path forward project. There are certainly situations today where the business case needs to be defined and this type of analysis is the right approach – especially when trying to evaluate extended, cross-functional value streams. We have found that many clients no longer have the appetite or time for this and want to move almost directly to implementation.
On the complete other end of the spectrum was the famous “kick the tires” visit of the 90’s. This was basically a site walk-through to look around and get a feel for the location and how good or bad it seemed, but very little data was used to make the assessment and the structure of the visit varied greatly depending on the consultant and their personal preferences.
These approaches both have their pros and cons. As the consulting model continued to evolve, we observed that getting a client a great answer quickly required a fundamental rethink of the approach with emphasis on the following issues:
To address these issues and meet the demand of clients who really needed a solid baseline assessment but didn’t want a full-blown analysis, we developed the Rapid Performance Evaluation (RPE) process. A holistic, effective and efficient approach to the initial gap analysis that could be done in a day and provides team-validated, benchmark scoring with an identified improvement portfolio of ranked opportunities for both the people and technical sides of the equation.
How did we do it? We looked at the gaps in traditional approaches and developed a set of 5 counter measures aimed at making the evaluation fast, relevant, user friendly and credible. Design considerations include:
Use a good template – To achieve speed, consistency and quality, use a great template. People are busy and have not planned for the interruption. Our templates are based on the idea, “This is what good looks like, let’s see how this operation compares.”
The template must be standard, yet flexible. Too rigid and the response will be “That doesn’t apply to us.” So, be prepared to modify to make it more usable for the situation at hand. We’ve found that the people and organizational parts change little between locations, industries, sectors, etc., but the technical pieces like flow, supply chain, quality, etc. usually benefit from some adjustment.
Limit the evaluation of operational metrics on the first pass – For any given operation there are about 10 metrics that tell the story. Things like inventory, quality, productivity, turnover (people), etc. We like to ask how difficult is it to get this information too. This tells us a lot about the operation and location’s leadership style. Vast amount of data does not always (read: rarely) translate into usable information. By usable, we mean available in a standardized format and used for running the business.
Identify and ask about the best few metrics for the operation and then use them as a guide for where to look more closely during the evaluation. Later on, more information and more analysis may be required, but for your initial look, keep it simple.
Apply change management from the start – When you ask people what they are doing and why they are doing it, its personal. But this engagement is essential because they know more about what they are doing than any outside observer. A non-threatening environment, supported by a skilled facilitator, will yield the best information. Don’t wait for “the real project” to start respectfully engaging the knowledge of the organization.
To make this work, the key is to quickly develop internal evaluation experts. For us, that means having a joint KG + Client team conduct the RPE. This is where standardized templates and processes prove their value as it enables us to easily on-board and train the client participants in how to do the evaluation. With a 60-minute orientation, the joint team is aligned and up to speed on what to look for during the tour and how we will do the individual and team scoring later. This facilitated, open and honest team discussion helps ease the dialog that occurs later when the team must come to consensus on certain performance measures.
Use a credible rating system – A rating system gives the organization a way to measure their improvement. The score is the baseline performance of the operation and clarifies the real gaps. As improvements proceed, better ratings show tangible evidence of the gaps closing. We use a series of three assessment tools that provide different ratings:
Prioritize opportunities and describe an implementation approach – Once the evaluation is complete and the gaps described, the question becomes, “What next?” This question must be answered at least at a high-level. A one-day RPE won’t yield a detailed implementation plan and business case. But, it will answer things like: top operational priorities, engagement problems, leadership mis-alignment and recommended next steps.
When evaluating performance, it’s difficult to achieve adequate results without incorporating an external objective view. That’s why we’ve found the RPE process to be so powerful. We have found a formula to bridge the gap between providing an unfiltered outside view, while incorporating the expertise and knowledge of insiders to accurately assess the current situation. It’s natural for those who are directly involved as part of the team to defend the work they do, so a balance must be struck. In one memorable situation the supply chain was so bad that simple commodity replacement parts were taking 8 weeks to obtain – crippling the operation. Yet in talks, the manager being hurt by the problem rated the supply chain a 5 out of 5: Perfect. These difficult discussions are almost impossible to have without a baseline measurement of “what good looks like” to test against and some objective external facilitation.
When done well, an evaluation of operational performance is a fantastic starting point for real change and improvement. When done poorly, it becomes simply another exercise in futility and another data point for “Why this stuff never works.” If our RPE process seems like it’s the right fit for you, give us a call or drop us a line.

In my earlier career before I became a Lean-head, I held progressively responsible engineering and management roles within the technology sector. Those were the days. Silicon Valley was positively sizzling — the engineer’s revenge. If you didn’t take at least three after-work meetings each week with your personal headhunter (aka, the Long Island Ice Tea enabler), you were branded a “going nowhere slacker”.
New breakthroughs were scheduled daily by suit-wearing big bosses far above my salary grade who vaguely recalled from college that Ohm’s Law was some advanced form of guided meditation. These were the same guys who had long since forgotten the importance of performing a credible tolerance stack-up… you know, one good enough that you’d trust the safety of your family with the product. Anyway, since no one told us we couldn’t develop new stuff all the time, and capital was positively e-v-e-r-y-w-h-e-r-e, we blissfully did make new things every day… uh… that is, blissful for the most part.
With some early performance wins on my part, and a willingness to accept accountability for my actions, my career swiftly blossomed into leading the development cycle for the hardware I used to touch. Like all the other new Project Managers, I thought my job was more or less to get people organized to meet contract and technical requirements. At the time, we used a genuine bleeding-edge breakthrough called the “Integrated Product Development Team” (IPDT). (May say more about that another time because it’s not what this post is about. For our purposes here, just imagine what it might be or refer to the link.)
Among the IPDT’s rollcall were many of my former colleagues from the high-tech trenches. That description of them mainly denotes that we took morning breaks together and were on the same after work (when not with our headhunters) beach volleyball squad. Sometimes we even accidentally put on each other’s lab coats — and then laughed about it. Still a crack-up.
The first time out of the chute with my very own IPDT I detected some interesting characteristics among my former frontline collaborators; qualities that I had not previously perceived through my 5% pink-tinted tech-nerd spectacles (caused by early-onset presbyopia from scanning too much fine print).
We now know that at the root of this problem was the influence of freshman philosophy and psychology classes foisted upon these poor souls before their brains had fully developed.
That one was harder for me to fathom as I had been acquainted with several of these folks since our foundations in public school. I was certain that calendar and timekeeping theory had been covered, even in home room… more than once. And it wasn’t that long ago. Of course, back then the bell sounded to change classes at the end of the period, so that helped bridge the gap.
Okay, I kind of get that one. I mean, things were changing so fast that – if – you simply waited for the fabled “optimized solution” with “better data”, you could easily justify taking four weeks to place an order for a simple digital multimeter — because hey, everyone knows that newer one will be way better.
As I pondered emerging perceptions concerning my mates and considered how to best manage my troubled sentiments about our workforce in general, I was also fortunate enough to work for a string of really excellent bosses who, in composite, laid down an easy to remember set of rules that absolutely addressed all of these concerns and has served me well. Now, it’s true that there are countless tomes available on the machinations of best-in-class project management that I might have referred to instead. On the other hand, these rules are simple enough to remember and actually use. For each, I’ll inform, then briefly expand upon the real 3 + 2 rules of successful project management – the only ones that genuinely matter.
Since you’ve been patient and probably only scrolled down two or three times to look ahead for some concise table that images well on the screen of your Galaxy S8+, I’ll now share them with you here.
(I mean, person… I mean, associate… I mean… oh, crikey… recurring attack of charm school political correctness. Thought I was cured. Sorry everyone.)
Later on, inspired by notable IPDT outcomes while observing only the prior three rules, I was then prepared to absorb the following two concepts that I’ve discovered apply almost universally… bonus rules I include just for you.
That’s it dear readers. The real 3 + 2 rules of successful project management. These should spare you years of tedious discovery and position you for speedy
domination, control, uh… leadership of your market space.

I recently read an article that asked the question: How many types of waste are there really? This was in reference to Lean and the original seven wastes in Taiichi Ohno’s iconic Waste Wheel, shown here.
The comments were interesting. Apparently there are tightly-held beliefs on this topic. Let’s try not to over complicate something that Ohno intended to be quite simple, but because waste is the red thread of all Lean, it’s worth consideration.
Purists believe that there are 7 wastes as described by the sensei and there shall be only 7 wastes. Period. Another faction makes the argument for adding the “waste of people’s intellect” or something similar. This notion has become increasingly popular over the years. Kaufman Global added it long ago, but I’ve always found the classification a bit difficult. Is it intellect, human potential, creativity, insight, involvement, et cetera? Unlike Ohno’s originals, these descriptors seem abstract and difficult to attach to an action.
The case for waste of intellect arose from the observation that bosses and managers tend to treat people like cogs instead of active participants in value creation. Ohno’s writings illustrate his struggles to help people understand. Who knows why he didn’t include it in his original work? Maybe he considered himself an “under-cover” social engineer and felt that sticking to hard assets was more pragmatic. Or maybe he didn’t want to too openly point out that management was missing the point? The gap shows no sign of closing soon.
If you want to get really basic, there is only one true waste: TIME. With Lean, time is incorporated in many ways: cycle time, value added time, non-value added time, downtime, uptime, etc. Ohno simply broke it down in a way that made it easy to identify obvious targets to be addressed with appropriate techniques.
My take: It doesn’t really matter. Waste can be subdivided many ways. If you think there are 20 different types of waste and this helps attack any one of them better; go for it. In the name of continuous improvement we must be willing to add or subtract in order to improve the system. Right? Yes. Be careful though: More choices seems somehow less Lean, doesn’t it?
Which brings us back to the concept of the waste of people’s intellect. When it comes to achieving operational excellence, a tremendous amount of time is lost by failing to engage people doing their daily work. Non-inclusion results in false starts, half measures, low sustainment and do-overs. Workshops and Kaizen Events may be common, but sustainable results are only achieved when people are tangibly connected to everyday improvement.
Any attempt to be operationally excellent means real and sometimes uncomfortable change; which always meets resistance in some form. Alignment is about getting everyone to support new ways of work. This is a cascading process where actions are different depending on ones place in the organization. If there was only one choice about what to align on however, it would be the need to engage everyone.
Engagement means giving people a voice in the work they do and holding them accountable for continuous improvement. Achieving broad engagement up and down the organization is tough for many. Kaufman Global uses structures like the Executive Steering Team, the Lean Daily Management System ® (LDMS ®), and Procedural Action Teams to force engagement. They’re simple enough to understand and do too. If methods are overly complicated, they are easier avoid.
When it comes to waste, everything revolves around time but it’s okay to define as many subdivisions as you like. If you had two to choose, I’d recommend alignment and engagement. When you get these right, smart people working together toward a common goal always solve the other problems.
If you want to learn more about Kaufman Global’s approach to engagement and alignment, check out SLIM-IT, Procedural Adherence and Lean Daily Management System. For a deep dive into the waste wheel and how it applies to Lean, check out our White Paper: Implementing Lean Manufacturing.
The third and final excerpt in a 3-part series from Kaufman Global’s updated white paper, Implementing Lean Manufacturing: A Holistic Approach.
In Part 1 and Part 2 we covered the genesis of Lean manufacturing, why “pull” is such a fundamental concept and how Lean is an integrated system that goes well beyond technique. Here, in Part 3, we close the series with prescriptive approaches for attacking each of the 9 forms of waste. In this installment we discuss:
For each of the forms of waste there are certain attack methods. We start with People Energy Waste because it is the most challenging for most organizations.
SLIM-IT, noted on the Master Jargon Chart section above (see the full chart in Part #2), is a pronunciation of the acronym for Structure, Lean (Daily Management System), Mentoring, Metrics, Teamwork, Tools, Training and Technology (SLMMTTTT). Kaufman Global’s SLIM-IT model is the primary engine of any Lean (or other) implementation because it aggressively attacks the people energy wastes that derail so many initiatives. Most organizations have ample technology, tools, training and teamwork “potential” to solve almost any problem or achieve any goal. The difficulty lies in compelling the right combination of the “Ts” to come together at the right time. This is what SLIM-IT does. Figure 6 presents the SLIM-IT model.
The Structure element of SLIM-IT employs several processes / mechanisms, including:
The building block of Lean is the intact workgroup. These are the hands-on associates who work near each other on similar processes every day. Each workgroup of ten or fewer people operates its own LDMS that nurtures improvement and sustains realized gains. LDMS compels, coaches, mandates, and supports workgroup engagement in applying the correct tools to minimize waste in their work area.
LDMS consists of six core elements:
The triangles represent the group’s improvement goals for individual keys for the next year. The improvement plan lists the specific actions required by the group’s members to attain the point goals. The chart and the accompanying improvement plan are posted on the group’s PVD.
These five elements, if implemented and maintained, provide a rock-solid foundation for any world-class Lean program. They provide the mechanism for each workgroup to take ownership of their work processes.
All other Lean tools and techniques will realize only a fraction of their potential if any of these elements are not implemented and rigorously practiced.
Mentoring is the next element of SLIM-IT. This is the day-to-day coaching of managers and supervisors in real time, on-the-job, as the tools and techniques of Lean are implemented. The coaching must be done by those who understand the why, what and how of applied Lean. Mentoring is the mechanism that assures that management behaviors at all levels will be changed sufficiently and over a long-enough period of time to infuse them into the organization’s culture.
Metrics get a lot of attention in traditional organizations but they are often misguided. The most common problem is an overabundance of them. Second, the metrics that are most interesting to the top of the organization are often difficult to connect with the day-to-day work. The Metrics in the SLIM-IT model can be described in three ways:
The linkage between these three types of metrics deserves careful consideration. Usually the top-level metrics get all the attention with little thought to how they are affected by micro-process improvements or measures that ensures broad participation.
Tools, teamwork, training and technology approaches are used by every organization in attempts to improve. Many of these approaches work if properly implemented. The key to their success is combining their usage within the other elements of SLIM-IT. Without a foundation of structure and coaching, tools, teamwork, training and technology will fail to deliver what they promise.
Workplace Management methods are used to minimize people work wastes. They include standard work, workplace organization and Kaizen.
The worksheets and templates used to develop standard work are extremely important for two reasons. One, they permit workers in an area to identify and measure micro-process waste that might otherwise be overlooked as insignificant. Two, in the process of attacking waste, workers develop the feelings of ownership that are so critical to the success of the people energy waste techniques. Figure 8 displays the “before” improvement portions of two types of worksheets for an actual cell.
The numbers on the Standard Work Instructions (SWI), shown in the left portion of Figure 8, represent worker actions. These actions are measured and classified as manual (hands-on) work, waiting, machine or walking on the Standard Work Combination Sheet (SWCS) shown in the right side of Figure 8. The cell is in trouble because it cannot meet its takt time of 65 seconds.
The “after” situation in Figure 9 shows significant improvement toward the elimination of three types of People Work Waste within the cell: walking, waiting and processing. This optimization develops over time. The workgroup is aware of their performance based on their metrics that are a visible part of their PVD board. Sometimes the improvements are incremental and part of the Kaizen Action Sheet System. Sometimes, the improvements are more abrupt and come from Value Stream Mapping or a Rapid Improvement Event. The point is that the standard work of continuous improvement that is embodied by LDMS is a major influence on workgroup, and therefore overall, performance.
Just-In-Time (JIT) methods address the quantity wastes of making too much WIP, inventory and movement. Some people refer to all of Figure 5 as JIT or Kaizen. While technically incorrect, the JIT association is frequently made because you cannot employ JIT techniques to remove quantity waste unless you also address the other wastes concurrently. The kaizen substitution derives from much the same logic, although the popularity of kaizen blitzes has made kaizen an all-purpose descriptor for Lean for many people.
There are four primary JIT methods: kanbans, leveling, Quick Set-Up (also known as SMED: Single Minute Exchange of Die), and preventive maintenance (PM). We have already addressed kanbans and work leveling to some extent earlier in the paper.
Error Proofing often referred to by its Japanese name, poka-yoke (pronounced “polka,” as in the dance, “yolk,” as in the egg, and “a,” as in bay), uses a variety of detection, warning, prediction and prevention mechanisms to catch or prevent errors at their sources. As you can imagine, the implementation of workplace management would automatically generate a number of error proofing actions (and vice-versa). Error proofing is a primary technique for quality improvement in Lean because it is so basic and easy for people to apply. One of the primary sources for error proofing ideas is via the Kaizen Action Sheet method contained within the Lean Daily Management System.
Six Sigma is a comprehensive set of practices that takes careful aim at variation reduction to improve product and service quality. It contains within it specific methods for statistical analysis, project management and problem solving and emphasizes the DMAIC model: Design, Measure, Analyze, Improve and Control.
As you can see from the above discussions, the fundamentals of Lean are not complex. Yet, few organizations pursue it as a key strategic goal. Many failures with Lean are derived from a “tool shopping” mentality. Rather than designing a step-by-step implementation of Lean, they attempt (either by accident or through management-led efforts) to cherry-pick bits and pieces of elements found in the “focus points” column of Figure 5. These organizations believe that if they install a few of the pieces, Lean will eventually happen on its own. This never occurs – especially since the isolated tools are typically accorded little management support and don’t mandate engagement. Examples:
It is essential to realize that Lean involves both a philosophy and its accompanying approaches and tools. They are mutually supportive and interwoven. If an adequate number of the tools and approaches are aggressively implemented – and enthusiastically coached at the micro-process (hands-on worker or “gemba”) level – the philosophy of Lean springs to life.
Simply stated, the full impacts of Lean can only be achieved by implementing a total systems approach.
Lean manufacturing is a people process, not a tool installation exercise. It is a journey, not an event. It’s an intensive and proactive effort that requires planning, resources and day-to-day management attention and coaching. It is not easy or painless and must be approached with the understanding that it will take time to change and even longer to create a new Lean culture. Those who endeavor to pursue it holistically will reap the significant performance gains that will allow them to win in increasingly competitive markets, provide significant shareholder value and by enabling an organization of engaged and empowered problem-solvers.

The following is the second excerpt in a 3-part series from Kaufman Global’s updated white paper, Implementing Lean Manufacturing: A Holistic Approach. In this paper we discuss:
In this installment we discuss why Taiichi Ohno’s original 7 wastes must be updated to include two new ones: Alignment and Engagement – which if not addressed will foil any implementation.
Lean is not “installed.” A self-regulating, Lean system is created by a continuous focus on eliminating small instances of waste or “muda” (muda is the Japanese term for “waste”). Waste is defined as any work that does not add value to a product or service. If the customer does not benefit from it, it is muda. All inspections, rework, repairs, walking, material movement, inventory of any sort, waiting, and so on are muda. They all cost money and produce nothing of value for the customer. Lean (pull) slowly evolves from a traditional (push) system as wastes are eliminated little by little. When an organization first begins to initiate Lean activities, it is a traditional system with perhaps a few Lean tactics being applied here and there. At some point, with dedicated effort, it becomes more of a pull system than a push system.
Figure 4 displays the four categories and nine types of Lean waste. This new model evolved from Taiichi Ohno’s original three categories; People (work), Quality and Quantity, and associated seven types of waste. In the late 90s, an eighth waste that acknowledged the value of people began to appear. That “waste” has been described in a number of ways, including: intellect, creativity, involvement, etc. In the time since it has become increasingly apparent that the people aspect still receives too little attention and prior descriptions have not been specific enough.
Kaufman Global gets more direct by describing the People Energy wastes of Engagement and Alignment. This draws attention to the elements that must be overtly addressed in order to make Lean really work and puts a finer point on the idea of holistic, integrated Lean. It’s necessary to do this because of the almost insurmountable implementation problems that many organizations encounter. Their struggles are driven largely by the fact that people energy wastes are not dealt with as an integral part of Lean adoption. Therefore, we have directly incorporated people energy wastes, along with ways to minimize them, into the basic conceptual model of Lean. The specific definitions of each type of waste are described below.
People energy waste arises from a failure to harness the potential that exists in all workgroups. This form of waste is the most important thing to address in Lean implementation or any other type of change initiative. Failure to harness people energy creates most of the significant problems that organizations encounter when they attempt to do something (anything) different.
Alignment Waste is the loss of value that arises when management and employees at all levels are not consistently aligned and energized to address critical issues. Making this happen is the sole responsibility of leaders and managers who are easily distracted. Alignment requires conscious and planned strategy and tactics that ensure messaging is consistent, priorities are established, communication is open and deviations are explained. “Flavor of the Day” or “Programs of the Month” are good indications of alignment waste. Good alignment means that you start, and stay, the course.
Engagement Waste is the loss of value that occurs when people do not have some control over the work they do. This is one of the toughest things for managers to abide because they feel like they are giving up some control – which they are. True engagement means requiring workgroups to measure their performance at a micro-process level and then expecting them to improve their performance over time. Many organizations waste a lot of energy on faux-engagement activities such as coffee talks and lunches with “their people.”
The idea here is to engage and align the organization via well-defined structures. All the good intentions and skills in the workplace cannot operate seamlessly if responsibilities, resources and personnel are not formally assigned and led. Structure requires a formally dedicated steering committee, work stream leaders and teams, explicitly assigned resources, schedules, charters, and champions. Alignment and engagement compel two critical outcomes that are essential change- management requirements for successful implementation: relevance and ownership.
Relevance: To sustain any initiative, people must work on issues that are, in some part, relevant to them personally. The most basic and beneficial aspect of good alignment and broad engagement results when individuals and teams are compelled to deliver on improvements and fixes within the processes they control. This creates, by default, an environment where much of the improvement activity is truly relevant to those doing the work.
Ownership: Human beings are territorial and proud. If they are associated with something, it is absolutely essential for them to believe that it is admired and respected by others. This tendency is wired genetically into us all. If people are not permitted to exercise some degree of control and power over their work place, they will not be inclined to identify with it nor will they strive to make it excel. This is the underlying basis for the outstanding performance of all self-directed workgroups.
Concerning all People Waste, understand that it’s not that the people are being wasteful but rather that these are wastes that are visited upon people by a non-Lean configuration of work.
People work waste arises from human actions involving processes. This type of waste is most analogous to the waste encountered in industrial engineering concepts. It can be divided into three categories: processing, motion, and waiting.
Processing waste is the result of inefficient work. Typical causes are inadequately trained workers, hard-to-use / locate tools or poor-fitting parts. Employees are hard at work, but there is a better way to do the job.
Motion waste is all movement that does not add value. All walking and reaching for parts or tools is muda.
Waiting waste is people waiting for parts, help, a machine that is broken or down for a die exchange, and so on. People can add no value to the product or service while they are waiting.
There are three types of quantity waste that arise because material (or data or paper) must be processed. This type of waste comes from creating too much inventory between workstations (WIP), Raw and Finished Goods inventory and material movement and transport – think; forklifts, stackers and trucks.
Inventory waste arises when inventory is not being used but has been paid for, perhaps has had value added to it, takes up space, requires expensive storage and retrieval systems and becomes lost, damaged and / or obsolete. Finished Goods inventory is even worse, as all of the intended value has been added and several weeks or even months may pass before it is paid for.
Work In Process (WIP) waste is inventory somewhere in the system between Raw Materials and Finished Goods. Whenever there is material waiting between two processes, it is waste. WIP waste occurs because process times are not balanced and matched with takt time.
Movement waste is all transportation of materials. Shigeo Shingo, the conceptual organizer of Single Minute Exchange of Die (SMED) and poka-yoke (error proofing) concepts, humorously observed that forklift and conveyor salespeople must routinely bribe traditional plant managers. Why? Because, he jested, no other mechanism could explain the incredible amount of unnecessary movement built into the processes of non-Lean plants.
Fixing defects is the sole quality waste. Each defect turns value-added work to waste and requires more nonvalue-added work to be repeated during rework or repair. Prior to the implementation of Lean, quality waste is usually the most visible waste due to its impact on customers and the tendency of a traditional push system to fail to recognize the other types of waste as significant. Ironically, reduction of the other wastes through Lean always results in a dramatic decrease in defects. This occurs even without the focused implementation of powerful tools such as error proofing or Six Sigma.
The next section presents an integrated discussion of Lean tools, concepts and implementation techniques. The tools and methods should not be separated from the implementation approach. While this paper does not provide a detailed examination of Lean tactics, it does present sufficient information for the reader to determine what they must learn in order to develop a successful Lean implementation initiative in their organization.
As muda is eliminated through the application of various Lean tools and methods, a pull system gradually emerges. Figure 5 presents the Master Jargon Chart of Lean Manufacturing. The Master Jargon Chart summarizes and presents the various Lean wastes, tools and methods into a single conceptual framework. Figure 5 is Lean; that is, in order to “do” Lean, the waste reduction approaches and corresponding tools and methods shown there must be comprehensively applied in an integrated manner.
All of these tools and approaches need not be implemented simultaneously. In fact, it would be a mistake to do so. Further, the criticality of each tool varies in different environments. This is why a “one-size-fits-all” Lean implementation is a mistake. While all successful Lean organizations use many of the tools to some extent, various tools are more comprehensively applied in certain environments than in others. As we discuss specific tools and approaches, this will become obvious.
The left two columns of Figure 5 present the four categories and nine types of waste described earlier. The structure of this model might suggest that each waste category is targeted by a specific approach and / or method. While this is true to some extent, all of the methods are extensively interdependent and interactive. You cannot “cherry pick” tools and techniques and expect long-term Lean success. In particular, if you do not employ the methods required to address people energy wastes, the other methods will fail to achieve competitively meaningful results.
To be continued. In Part 3 of this series, we provide describe a fail-proof system for implementation. Or, if you’re ready to read the entire white paper now, click here to access it via our Resources page.
The following is the first excerpt in a 3-part series from Kaufman Global’s updated white paper, Implementing Lean Manufacturing: A Holistic Approach. In this paper we discuss:
In this installment: THE EVOLUTION OF LEAN AND WHY PULL IS SO IMPORTANT, we describe the foundations of Lean over the past half-century and why pull vs push is one of the most fundamental aspects of any Lean system.
Part 2 discusses why Taiichi Ohno’s original 7 wastes must be updated to include two new ones: Alignment and Engagement – which if not addressed will foil any implementation.
Part 3 provides an easy to understand table that shows the systemic nature of Lean: wastes, approaches, methods, tools and results and describes a fail-proof system for implementation. For over 20 years Kaufman Global has pioneered the interface between people and process, always with engagement and alignment at the core.
Kaizen is a Japanese word that means “small, ongoing good” (kai) and “good, little, for the better” (zen). The term has come to mean small, continuous improvements by hands-on workers all the time.
Lean manufacturing has become synonymous with world-class operational excellence. Under various names (synchronous, pull, demand flow, flexible, cellular, just-in-time, one-by-one), Lean is the single most powerful strategy for improving a production operation’s competitiveness. The dominant players in every market segment are aggressively implementing Lean as a strategic weapon because they realize they have no choice. If they don’t “do Lean” and stay Lean, they will quickly fall behind the market leaders because they are less able to adapt to an ever-changing competitive environment.
This white paper is directed at organizations that are either eager Lean practitioners or those who have not yet had a Lean awakening. Both will find value in its explanation of the foundations and basic mechanics. Additionally, this paper describes Kaufman Global’s specific approach to Lean implementation and our learnings over years of working with clients. Our method is holistic and pragmatic, reduces implementation time, increases benefits and ensures sustainability. Kaufman Global has pioneered several techniques that are in wide use across a broad spectrum of industries and business today, including: the SLIM-IT® model for implementation, Lean Leadership®, the 20 Keys® and the Lean Daily Management System® (LDMS®).
Lean manufacturing, or Lean, is an integrated leadership philosophy, management system and set of tactical methods / tools that focuses on creating an operation with minimal amounts of nonvalue-added activity, inventory (Raw, Finished and Work-In-Process) and errors. The primary engine for eliminating nonvalue-added elements in Lean system is the employees who do the hands-on work.
While the mechanics and approaches of Lean may not be clear to everyone, there is little doubt concerning the magnitude of potential benefits. Years ago, in order to get people interested in the notion of Lean, it was necessary to quote double digit percentage savings from process improvement. Without making that list here, in our experience any process is capable of a 10 – 30% improvement if Lean is applied with some rigor. This is in any and all dimensions whether it be cycle time, lead time, quality, inventory, customer satisfaction, absenteeism, etc.
Results like this cannot be attained by chance or half-hearted, informal initiatives. They can only be generated through carefully planned and aggressively supported efforts that are overtly led by management. Isolated improvements have no chance of leading to an organization-wide transformation of day-to-day behaviors, expectations, metrics and the entire system of work.
Figure 1 is a conceptual diagram showing the progression of Lean between the 1940s and today. Lean would not have emerged as a structured system when it did (or at all, perhaps) if it had not been for two circumstances. The first was the condition of Japan after World War II. Totally devastated and with few resources, Japan could not compete with other industrialized economies on costs, volume or quality using standard mass production approaches. There wasn’t enough money to build modern factories or buy modern equipment. Japanese manufacturers had to “make do” with what they had; and they had very little. This massive handicap created the ideal conditions for the true catalyst of Lean to operate.
This second circumstance was the pioneering thinking of Kiichiro Toyoda, Taiichi Ohno, and Shigeo Shingo. Their focus on low-tech, pull systems and the elimination of waste evolved into the Toyota Production System (TPS) over the period from 1945 to about 1975 (the original, Toyoda, was changed to Toyota for American consumers). The 1990 book, The Machine That Changed the World by James Womack, et al, popularized the term Lean manufacturing to refer to the TPS and its derivatives. Other generic names for the TPS are flexible, cellular, one-by-one, pull, synchronous, demand-flow and World-Class manufacturing. Also used are just-in-time and kaizen although both are only elements of the TPS, not the entire system.
Starting in the mid-1980s, the large automobile manufacturers adopted many of the basic principles of the TPS, but each changed the name to something that sounded more “home grown” to their employees, customers and shareholders. Other companies have since taken the same approach. Thus, it is common to find that Company X has the “X Production System” in place. Peel back these “labels,” and you find significant elements of the TPS underneath.
During the 1990s, it became apparent that there was plenty of room for Lean application far flung from automotive assembly and well beyond the factory floor. This started the integration of methods and techniques that is still going on today – Office Kaizen is one example. As organizations from all industries, sectors and segments embraced adaptations of the TPS, new tools and methods were developed and Lean continued to evolve.
In the mid-2000s, the term operational excellence or “OpEx” started becoming the popular catch-all phrase for operational improvement of any kind. It allows for the inclusion of a multitude of techniques – especially the integration of Lean and Six Sigma – and is often more acceptable to the ears of those in non-manufacturing pursuits. The generality of the term is also its weakness because anyone doing anything to improve performance can proclaim they have OpEx – which may or may not be true.
While the basics never change, the Lean of today has many additional bells and whistles that Toyoda, Ohno and Shingo did not develop but would have welcomed. Anything that enhances the fervent elimination of waste is part of Lean.
A critical distinction between Lean and traditional systems is the pull philosophy of Lean versus traditional manufacturing’s push philosophy. Figure 2 displays the mechanics of a typical push system with three employees working on three consecutive processes. The curved arrows represent sequential actions of each process step. In this example, each of the three workers does his / her work at the same time independently and then passes the completed item to the next worker. We assume that each worker performs each and every task at a constant rate of speed.
The “start” scenario illustrates the situation in the cell as it has just started to work on a new product. The Process A worker has four pieces of Raw inventory waiting to be worked. There are also four pieces of Work-In-Process, or WIP, waiting for both the Process B and Process C workers. Each worker has one piece of work at their station. There are four pieces of Finished Goods waiting to be picked up after Process C. In Figure 2, the processes are not balanced. We know this because the workers, operating at a constant rate of speed, require different amounts of time to do their work. Takt Time (TT) is noted for each process. Because at least one of the workers is over the Takt Time (TT), it will be impossible for the three-person workgroup to meet customer delivery demands unless additional resources in the form of time or people are added.
TT is obtained by dividing the total amount of work time in a day or shift by the required output. That is: Takt Time = total time in seconds / required output. The bar graph below each process represents the amount of actual time that each worker requires to perform their work to the product.
The rate of completion of work for each process varies because the work is unbalanced: Process C takes the longest, B is the fastest. Process A tasks are the only ones that match the Takt Time exactly.
After some period of time operating under the typical push philosophy, the original “start” situation has evolved into the “later” example shown in the bottom half of Figure 2. With a starting level of four pieces of inventory between each worker, Worker B frequently ran out of material because they are out of balance with the preceding process (A). The supervisor or manager, uncomfortable at seeing an idle worker and believing that any work is better than none, ordered that more inventory be added so that Worker B could stay busy. This typically happens as managers strive to make “earned hours” or “standard labor hours” look better. If the workers in Processes A, B and C are operating machines, the quest for better “absorption” numbers creates additional pressure to build up inventory.
Raw material accumulates with Worker A because it is pushed to the operation by Materials Management and Production Control. More and more inventory is added until all workers are kept busy all the time. The result is masses of inventory of all types – Raw Materials, WIP and Finished Goods. Upon seeing busy workers and a lot of inventory, managers receive the false perception that considerable value is being added and that there is a lot of product almost ready to meet customer demand.
The total output of the combined processes of cells A, B and C can only ship at the rate that Process C can complete the work. If any process downstream has a problem, other upstream processes will continue to churn out inventory. All of the WIP and Raw inventory is irrelevant to meeting customer requirements. All of the labor that is added to inventory that cannot be shipped is waste – and no, it is not “pent-up value.”
Worst of all, because everyone appears busy, the issue of unbalanced work between the three workers and the inability of the cell to meet takt time is seldom addressed.
This is the root cause of the entire inventory buildup. Rather than focusing effort on balancing the work in the cell, the push reaction is to resort to overtime, more workers, more expensive equipment, or all three.
Note the diagonally striped squares that appear in the “later” scenario of Figure 2. These are “problem” assemblies: a part was bad, an assembly error was made and / or a component was missing. When one of these problems occurs, the unit is pushed off to the side for later assessment. However, in most push systems, these problems are rarely addressed — and, when addressed, never timely. With the organizational imperative to stay busy and make more, the problem units appear insignificant among so much other inventory.
Figure 3 presents analogous “start” and “later” scenarios for a pull system. A detailed examination of demonstrates the power of a pull system to overcome the problems created by the push approach. In the “start” configuration, the times for each process to complete one unit are identical to those in Figure 2, as is the TT.
The first thing noticeably different about Figure 3 is that there is little inventory. This is not something that happens all at once when transitioning from the Figure 2 push system, but is a gradual result of moving towards a pull system. The second major difference is that the three processes do not work independently. Work is always “pulled” from upstream.
The pull begins when the completed unit at station one (1) is removed. This creates an empty spot, which generates a need that pulls the completed unit from Worker C. This pull message is called a kanban (denoted by dotted box in Figure 3).
A kanban can be a spot on the floor, a pallet or a piece of paper attached to the material or the material’s container. Traditionally, it was a card or sheet placed in a see-through pouch. The kanban states what it can accept.
For example, if a pallet is the kanban and a pallet can hold 16 assemblies, Worker C could continue to place work on the kanban until it has reached its limit of 16.
At that point, no more units could be added to the kanban. Worker C would have to stop working after completing the unit in front of him and wait until the kanban was emptied. In our example, the kanban only holds one piece. If the downstream kanban is full and Worker C has completed work on the at their station, they must stop working and wait. Nothing can move without a kanban, only Production Control can create new ones.
The beauty of the pull system is that if there is a problem at a downstream process, the entire line stops. No worker is permitted to work on another unit and / or build up inventory unless a kanban arrives. The “later” scenario in Figure 3 shows that the three processes are more balanced than at the “start” scenario. In a pull system, there is a continuous effort to balance work between adjacent processes workers and cells to eliminate waiting and reduce WIP inventory.
Also note that there are no problem units in the later scenario. Since inventory is not pushed along the production sequence, each problem unit in the pull scenario creates an “empty spot” in the process chain that cannot be hidden by WIP inventory. Management and employees are energized to address problems by the very nature of the pull system. As a result, errors decrease and quality improves.
To be continued. In Parts 2 and 3 of this series, we update Ohno’s original waste wheel with the most dangerous waste of all: people energy and provide an easy to understand table that shows the systemic nature of Lean: wastes, approaches, methods, tools and results. Then we describe a foolproof template for implementation. If you’re ready to read the entire white paper now, click here to access it via our Resources page.
Kaufman Global helps clients solve complex problems and drive fundamental improvement. We engage when people and process collide – places where expertise and leverage can speed results. Even when an organization knows there is a problem, understanding operational performance, getting to solutions and knowing which levers to adjust can often benefit from outside perspective.
Over the past few years, we’ve observed that clients want answers faster than ever before. And while it could be that “time is money,” it seems to us that it’s more related to the frenetic pace of, well, everything these days. Headlines and “apps” often don’t dig deep enough and the “Ready, Fire, Aim” approach has great potential for missteps.
To meet the demand for fast but thorough answers, we devised an innovative method for quickly getting to the heart of the matter – operationally and organizationally. Our Rapid Performance Evaluation (RPE) uses a standard work approach to cut the time required for credible solutions to about a day. How, you ask?
Instead of only identifying and prioritizing process problems, the RPE delivers tangible feedback and scores that can be used to immediately take action to improve. The RPE:
The process begins by on-boarding the team and communicating with site leadership. It ends with a report to same. Core attributes of the Rapid Performance Evaluation are noted below.
The gemba is the place work is done. It’s the shop floor, the office, the warehouse, the lab or the medical unit. It embodies the concept of “Go look, go see” and is a vital step in collecting information for analysis. We’ve found it helpful to review immediately before the visit what we’re trying to “see”, so we use a standard set of definitions to focus our attention. For example, in an office environment one thing we look for is communication between functions. In a factory we want to understand how material is moved (pushed or pulled) and stored (inventory) from one location to the next. Lots of paperwork is not needed for reference. Our optics have been adjusted ahead of time so the visit to the gemba can be for observation and understanding. We need to keep our eyes and ears open.
Templates are used to compare existing practices to best known practices. With the RPE, simple but proven definitions and an intuitive measurement system make it easy to get everyone on the same page when it comes to scores and ratings. We look at factors that correlate to overall performance, such as quality systems, teamwork, continuous improvement capability and material and information flow. The correlation factors provide a big-picture view and point to overarching or systemic causes affecting performance.
For more discrete aspects of the operation, we use the Kaufman Global 20 Keys ® to evaluate 20 critical elements that affect efficiency and effectiveness. For each key, the tool ranks the current level of performance using a 5-point scale where 1 is “Traditional” and 5 is “Currently Invincible”. Levels are described simply so the requirements for achieving the next level of performance are easily understood. The 20 Keys dig a little deeper than the correlation factors by identifying and prioritizing specific things to work on.
No matter how good the templates and rating systems are, they don’t account for the human factor. Opinions matter. During the course of the visit we interview key leaders and stakeholders. This usually means functional heads who have valuable insights and who will play a critical role in any changes moving forward. We start to see how much (or little) agreement there is about the underlying issues. This is an area where being external to the organization is a key advantage. Functions are typically protective of their turf. Outsiders can ask more probing questions. If there is a significant difference between what we hear from the leaders and what we see on the ground, we sometimes opt to survey the organization. This can help identify broader organizational issues.
The RPE is done with a small joint team comprised of Kaufman Global and the client. Since the method is standard, well defined, intuitive, and template driven, training for the client participants can be completed at the start of the day. The real benefit of this simplicity becomes clear at the end of the day when scoring begins. After we’ve completed the tour and interviews, we individually rate and rank based on our personal observations. Then, we come together to discuss and negotiate consensus results. The evaluation is better because it consolidates multiple views, experiences and vantage points and compares actual performance against intuitive and easy to understand benchmarks.
Any operation can be assessed for performance quickly if the method considers all of the output requirements and integrates change management approaches. The RPE gives leaders rational ratings of performance, a clear understanding of organizational challenges and confidence that they’re spending energy in the right places.

People and processes come together to deliver products and services. Like a ball of string collected, complexity builds as things are added to accommodate the dynamic environment: organizations, procedures, technologies, reporting, etc. This “growth” happens incrementally and naturally in every business. Simplification can overcome complexity, but it takes energy to accomplish.
When two entities merge and attempt to integrate, the chaos is more obvious. Either way, the interactions are seldom or appropriately examined to determine what can be eliminated. Ultimately, the patchwork of fixes and micro-solutions generate systems that are more complex than they need to be. They are difficult to understand, standardize and control.
Complexity doesn’t automatically resolve itself. Some organizations endeavor re-design from time to time, but the work is typically limited in scope and stays inside functional boundaries. Here, there are plenty of examples of success in areas like Finance, Manufacturing, Product Development, etc. When we explore enterprise value streams that cross boundaries―for example the alignment of Sales, Product Development and Production, it gets a little tougher. Even so, opportunities to improve competitiveness are vast, therefore it makes sense to take a broader approach and navigate the stream through the enterprise. Results are more assured when the initial work is well planned and executed with precision.
A structured workshop is the best way to begin. This may be a single event or a series of sessions. It goes beyond getting a few people together to compare ideas. Top considerations are:
To determine scope, start with the system of people and processes that you have; the current state. Some will argue it’s better to begin with a clean-slate, but really, there is no such thing. In rare situations where there is no process to begin with, gaining a systems understanding without preconceived notions is more or less impossible. Besides, in most cases, products or services are already flowing. So start here to decipher the variables that are adding value.
Once you’ve got an idea about the scope of work, it’s time to get the right leadership engaged. First, determine the major processes and or functions that are part of the system. Then identify the single point of control for all of them. For many organizations, the control point for value streams that bisect the enterprise is the CEO. This isn’t so surprising when you consider the rich mix of silos, shared services and dual reporting structures that exist within most organizations. Single-point control at high levels is the main reason simplifying enterprise value streams is difficult, and why we often settle for optimizing functions or sub-processes. Don’t settle.
The control point then directs the functional leaders to participate by forming a coalition to govern the progress of the workshop (and beyond). This direction is the catalyst for action and it is a critical step. The task often requires more effort than initially expected, so be prepared with enough up-front work to make an effective case for change.
The workshops are staffed by individuals who work inside the existing system and therefore understand the most about what it delivers and how it functions. They also tend to defend the status quo but will probably be part of the change moving forward, so get them involved them early. You’re digging into things that people have built over time. Don’t underestimate the work required to keep this team motivated and on track.
Include some who don’t operate the existing system to get an unbiased view and to ask the “obvious” questions. In the ensuing conversations, you’ll hear “You don’t understand.” a lot – which is exactly what we want. Through these interactions, the team gains clarity about the system as a whole, instead of just their part of it.
The workshop decision is taken, simplification is an objective, the processes and people are known and an accountable Steering Team is enlisted… all good. So far the task at hand doesn’t seem too daunting. Now, as part of the workshop, go beyond simplification design and consider implementation. What will it take to operationalize the changes?
Workshops get things rolling by providing an output that describes processes at a high level. As the future state becomes current state in the real world, change is managed and kinks are worked out in-situ. The new system is built by standardizing processes as they emerge and then attaching and adhering to relevant procedures. Don’t add complexity back in by over-prescribing. Simpler definitions are more likely to be adapted, provide fewer options for things to go wrong and give more room for value-driven decisions to be made at the right level.
Complexity happens naturally. Simplification does not. People are frustrated working in bloated, ineffective and inefficient systems. There are no silver bullets, but smart design is a great starting point. Use an inclusive, holistic approach to extract solutions, identify value and restructure the work. Then engage the organization for extraordinary results.
