Sensei

Sensei is a Japanese term that translates literally as “one who came before”. It designates a teacher or someone who has achieved mastery of a subject or skill. It is a term of respect and honor.

In the world of Operational Excellence, it is associated with Lean and the Toyota Production System (TPS). As these methods expanded beyond Japan and Asia, it became fashionable to have a Sensei to instruct and inform. It is most commonly used by those who are or were indoctrinated into the world of Lean via the Toyota Production System and its affiliates.
