The six measured dimensions
Foundations
Lean Six Sigma principles, roles, value, waste, and project logic.
Map one real process from customer need to value, waste, project charter, roles, and expected financial impact.
Define
Problem framing, VOC, CTQ, chartering, stakeholders, and SIPOC.
Rewrite a real problem as a measurable gap, define scope boundaries, and connect VOC to one CTQ.
Measure
Operational definitions, data plans, MSA, capability, and baseline performance.
Create an operational definition and data plan, then state how you would verify measurement repeatability and reproducibility.
Analyze
Variation, root-cause logic, graphical analysis, and hypothesis-based evidence.
For one suspected cause, write the evidence needed, the comparison or test, and the decision rule before seeing the result.
Improve
Solution selection, risk assessment, pilots, mistake-proofing, and optimization.
Compare three countermeasures using impact, effort, risk, and reversibility; design a small pilot with a success measure.
Control
Control plans, SPC, response plans, standard work, and handoff.
Draft a control plan with metric, frequency, owner, limits, reaction rule, and escalation path.
How to study the framework
- Start with the problem and the decision, not the tool name.
- Connect every measure to an operational definition.
- Separate evidence of cause from correlation.
- Choose improvement and control methods that fit the verified problem.
