APMG LSS Green Belt study plan

APMG LSS Green Belt · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Define

  • Define Lean Six Sigma and distinguish Lean waste reduction from Six Sigma variation reduction

  • Identify the five phases of DMAIC and state the purpose and key outputs of each

  • Classify the eight Lean wastes (TIMWOOD) in three workplace or service examples you know

  • Draft a problem statement and goal statement that pass the SMART and 'no solution baked in' tests

Your checkpoint

A one-page charter draft for a real or realistic process problem, containing problem statement, goal statement, scope, and at least three classified wastes

Week 2

Define

  • Construct a SIPOC diagram for the charter process with at least five process steps

  • Distinguish VOC from CTQ and translate two customer needs into measurable CTQs

  • Select team roles (sponsor, champion, black belt, green belt, process owner) and justify each

  • Map the charter's stakeholders and rate their influence and interest

Your checkpoint

A completed SIPOC plus a CTQ tree with at least two measurable CTQs and a stakeholder grid

Week 3

Measure

  • Distinguish discrete from continuous data and select the correct measurement scale for three given metrics

  • Explain accuracy versus precision and identify how each is compromised in a described measurement system

  • Build a data collection plan naming what, where, when, who, and how for each metric in your charter

  • Calculate basic descriptive statistics (mean, median, mode, range, standard deviation) from a small dataset

Your checkpoint

A data collection plan covering at least three metrics, with descriptive statistics computed and interpreted for one metric

Week 4

Measure

  • Compute process capability indices (Cp, Cpk, Pp, Ppk) and state what each reveals about centring versus spread

  • Interpret a histogram and a run chart to describe shape, centring, and time-based patterns

  • Explain the purpose of an MSA and when attribute agreement analysis is used

  • Calculate rolled throughput yield and sigma level for a simple multi-step process

Your checkpoint

A measurement baseline report for your charter metric including a histogram, a run chart, capability indices, and a stated sigma level

Week 5

Analyse

  • Build a cause-and-effect diagram and a 5-why chain that reach verifiable root causes rather than symptoms

  • Construct a Pareto chart and apply the 80/20 rule to prioritise causes

  • Select the appropriate hypothesis test (t-test, chi-square, ANOVA, or correlation) for four described scenarios and justify each choice

  • Distinguish correlation from causation and identify confounders in a described dataset

Your checkpoint

A root cause analysis pack containing a fishbone, a Pareto chart with prioritised causes, and a justification table for four chosen statistical tests

Week 6

Analyse

  • Interpret p-values and confidence intervals correctly, including what they do not prove

  • Explain Type I and Type II error and relate them to alpha, beta, and sample size

  • Apply FMEA by scoring severity, occurrence, and detection and computing RPN for five failure modes

  • Use a scatter plot and regression output to describe the strength and direction of a relationship

Your checkpoint

A validated root cause summary naming at least two statistically supported causes, with an FMEA table ranking the top five failure modes by RPN

Week 7

Improve

  • Generate improvement options using brainstorming, benchmarking, and mistake-proofing

  • Select and justify solutions using an impact/effort matrix and a weighted decision matrix

  • Apply 5S, poka-yoke, and standard work to a described process and predict the effect on the key metric

  • Plan a pilot with defined success criteria, sample size, and a before/after comparison method

Your checkpoint

An improvement plan with at least three prioritised solutions, a completed impact/effort matrix, and a pilot design with explicit success criteria

Week 8

Improve & Control

  • Design a control plan naming metrics, owners, frequency, and response actions

  • Select and construct the correct control chart (X-bar and R, p, c, or individuals) for a described data type

  • Explain how to set and respond to control limits and distinguish common from special cause variation

  • Document standard work and a response plan so the gain is sustained and handed to the process owner

  • Assemble a full DMAIC storyboard linking charter, baseline, analysis, improvement, and control

Your checkpoint

A complete control plan with one correctly chosen control chart and a final one-page DMAIC storyboard suitable for a tollgate review

Milestones

Week 4: Pass a 20-question timed quiz on Define and Measure domains at 80% or higher, and have the charter and baseline report reviewed against a checklist

Week 6: Correctly select and justify the right hypothesis test in 4 of 5 unseen scenarios, and explain p-values to a non-specialist in under two minutes

Week 8: Complete a full-length mock exam scoring at least 75% overall with no domain below 60%, and present the DMAIC storyboard end to end
