Efficiency

Efficiency is the ability to accomplish a task, process or action with little waste. It is often expressed in terms of time or energy.

Efficient is a quantitative concept that evaluates the magnitude of something whereas effective is a qualitative concept that evaluates degrees of good or bad. In an operational context, efficiency is a measure of productivity: “As the process became more efficient, production increased dramatically.” Lean and Six Sigma methods attack waste and variation and therefore make processes more efficient and effective.Process Efficiency and Effective Methods Chart
