The Defensible Number: A Complete Lean Six Sigma Field Manual
Every DMAIC phase, every formula worth memorising, and a test selector that tells you which statistic to run.
PDF · 21 pages · Aug-2026
Lean Six Sigma is the oldest working discipline we have for making a number defensible. This 23-page field manual collects it in one place, written to be used rather than read cover to cover. Start a project on Monday without opening a textbook. Free to download, print ready.
What is inside
- All five DMAIC phases with the question each one answers, the deliverables it produces, and the tollgate exit criteria you cannot skip
- The exact wording of a problem statement and a SMART goal statement, with a worked example carried through Analyze
- Capability and yield formulas, the sigma to DPMO conversion table, and what poor quality actually costs at each level
- A statistical test selector covering twelve common questions, plus the control chart selector and the eight out of control signals
- A metrics library, the eight wastes, the Lean toolkit, and the sponsor questions that catch a failing project at the gate
