In a conversation with an outplacement advisor, I introduced myself as a Lean Six Sigma expert. His reaction was honest: he did not like Lean because he had seen it used as a management excuse for reorganizations and job cuts.
That reaction matters because many people have experienced improvement programs that forgot the most important principle: respect for people.
Real Lean is not a language for cutting jobs. It is a way to improve how value flows to the customer while reducing waste, frustration, and unnecessary effort. In a serious Lean culture, people are not the waste. The waste is in the system around them.
My understanding of Lean started with Lean Thinking in 2001. What impressed me was not only the efficiency logic, but the culture behind it: continuous improvement, ownership, and respect.
Later, I worked for one of Toyota’s tier-one suppliers. Daily logistics, just-in-time routines, and disciplined flow were not slogans. They were operating practices designed to reduce waiting, excess inventory, and poor handovers.
A simple way to describe Lean is this:
- See waste.
- Remove waste.
- Help people improve the value flow they work in every day.
Six Sigma brings another dimension. It gives structure to complex problem solving through DMAIC: Define, Measure, Analyze, Improve, Control. It helps teams move beyond opinion and understand variation, root causes, and measurable change.
Agile extends similar ideas into digital and knowledge work. Small batches, feedback loops, and visible work are not fashionable rituals. They are ways to improve flow and reduce delay between intent and value.
The problem is not Lean, Six Sigma, or Agile. The problem is using them without respect, without system thinking, and without a clear connection to customer value.
Improvement is not cost-cutting. Done properly, improvement is value creation.
