APMG LSS Green Belt study guide
APMG LSS Green Belt · Work through your exam, one topic at a time.
The APMG Lean Six Sigma Green Belt is a professional certification intended for practitioners who lead or support process-improvement work within an organisation. Green Belts typically combine a working knowledge of Lean thinking - the systematic removal of waste from a process - with the Six Sigma statistical toolkit used to reduce variation and defects. Holders are usually expected to run improvement projects of moderate scope, often alongside a Black Belt or sponsor, and to apply the DMAIC lifecycle: Define the problem and business case, Measure current performance, Analyse root causes, Improve the process, and Control the gains so they persist. Preparation generally combines formal training with hands-on project work. The APMG LSS Green Belt study guide has 5 sections and about 1,497 words.
01Define: Scoping the Problem and the Project Charter
The Define phase converts a vague complaint into a bounded, measurable project. The central deliverable is the project charter , which fixes the problem statement, goal statement, business case, scope (in and out), team, sponsor, milestones and expected benefit.
319 words, about 2 min02Measure: Baselines, Measurement Systems and Capability
Measure establishes a trustworthy baseline. The candidate must understand data types (continuous vs discrete/attribute) because they determine which tools are valid later.
293 words, about 1 min03Analyse: Finding and Verifying Root Causes
Analyse turns data into verified causes. Start with process mapping and value stream mapping to see where flow breaks, then use stratification to split data by shift, machine, supplier or operator - patterns often hide in aggregate figures.

Improve converts verified causes into changes that move the metric. First generate candidate solutions with brainstorming , benchmarking , mistake-proofing (poka-yoke) thinking and lean flow tools - 5S, standard work, cellular layout, setup reduction, kanban and pull.
290 words, about 1 min05Control: Holding the Gain
Control makes the improvement permanent. The candidate must know the control plan - the document naming each metric, its specification, measurement method, sample size and frequency, the responsible person, and the reaction plan when it goes out of control.
