Welcome to Part 3 of a 5-part series on Lean Design. In Part 1 I made the case that the achievement of “flow” is a major goal in the design of a Perfect Value Stream, and in Part 2 I discussed different ways to measure flow and why this is important. In this lesson I’ll cover the step-by-step method for designing a value stream that can flow. Think of this lesson as “Lean Industrial Engineering”.
