Six Sigma Green Belt and Black Belt Training Capability analysis before and after, with the charts
Six Sigma Green Belt and Black Belt Training
0% Completed
M1 — Six Sigma: DMAIC and the Belt Structure
What Six Sigma is: variation, defects per million and the goal

The DMAIC cycle and the tollgate question asked at each stage
Reading
Belt roles: champion, master black belt, black belt and green belt
Reading
How a belt project is chosen, funded and staffed
Reading
DMAIC against DMADV: when you improve and when you design
Reading
Lean thinking alongside Six Sigma and where the two pull apart
Reading
M2 — Define: Voice of Customer and the CTQ Tree
Voice of customer: where the data comes from and how it is collected
Reading
The critical-to-quality tree from a customer need to a measurable one
Reading
CTQ, critical-to-process and the specification you are measured against
Reading
SIPOC: suppliers, inputs, process, outputs and customers
Reading
The project charter: problem, goal, scope, owner and the cost of inaction
Reading
Benchmarking, where the target comes from and why the target matters
Reading
M3 — Measure: Process Mapping, Data and Measurement Systems
Process mapping and the SIPOC boundary around the process
Reading
Operational definitions: the same measure written the same way twice
Reading
The data collection plan: type, method, sample size and frequency
Reading
Measurement system analysis: gauge repeatability and reproducibility
Reading
The baseline: what the process actually does before you touch it
Reading
Data integrity checks and the errors that quietly skew a result
Reading
M4 — Analyse: Capability, Hypothesis Testing and Root Cause
Process capability: Cp, Cpk, Pp and Ppk and the assumption behind each
Reading
Sigma level: how the number relates to defects per million opportunities
Reading
The stability check: never quote capability on a process out of control
Reading
Hypothesis testing: p-values, confidence intervals and sample size
Reading
Root cause analysis: 5 Whys, fishbone and the difference between them
Reading
Separating the vital few from the trivial many with a Pareto analysis
Reading
M5 — Improve: Solutions, Pilot and Cost-Benefit
Choosing a solution: eliminate, reduce variation or control the cause
Reading
Design of experiments: factors, levels and what a fractional run buys you
Reading
Pilot testing: scope, duration, data to collect and the stop rule
Reading
Cost-benefit and the business case for the improvement
Reading
Failure mode and effects analysis on the changed process
Reading
Lean tools inside the improvement: waste, 5S, standard work and pull
Reading
M6 — Control: Control Charts and Sustaining the Gain
Control charts: how the limits are calculated and why they move
Reading
Choosing a chart: X-bar and R, I-MR, p, np, c and u for your data
Reading
Run rules for special cause: a point outside, a run, a trend
Reading
The control plan: what is checked, how often and by whom
Reading
Handing the improved process to the process owner with training done
Reading
Sustaining the gain: audits, reviews and the standard work that holds it
Reading

Why a measured improvement still fails when the people do not change
Reading
Stakeholder analysis for an improvement that touches daily work
Reading
Training the operators and the new standard work they will follow
Reading
Resistance: the questions behind the resistance and the answers
Reading
Choosing a belt project: size, impact, data availability and sponsor support
Reading
The documentation a belt certification asks you to produce
Reading
M8 — Capstone: A Full DMAIC Project and Belt Evidence
Capstone: running one DMAIC project on a real process with real data
Reading
Charter, SIPOC, CTQ tree and the measurement plan in one pack
Reading
Capability analysis before and after, with the charts
Reading
Root cause analysis and the improvement you piloted
Reading
Control plan, handover and the benefit you can claim
Reading
Assembling the evidence pack for your belt certification and your interview
Reading
