Statistics should answer process questions—not bury the team in calculations. Ben and Maya explain how Green Belts use Pareto charts, histograms, scatterplots, box plots, control charts, and capability analysis to understand variation, relationships, and process performance.

Test your knowledge with a cumulative 60-question Green Belt mock examination. Ben and Maya review Lean, DMAIC, waste, value-stream mapping, project selection, teams, statistics, root-cause analysis, improvement, control, and exam strategy. These are original educational practice questions—not actual certification exam questions.
Finding the cause is not the end of DMAIC. Ben and Maya work through Green Belt scenarios involving solution selection, pilots, implementation, risk, control plans, standard work, monitoring, response plans, and choosing the best next step on the exam.
Blaming human error rarely explains why the process permitted the failure. Ben and Maya examine symptoms, contributing factors, direct causes, and root causes using the Five Whys, fishbone diagrams, cause verification, process evidence, and mistake-proofing.
Generating ideas is easy; choosing the right one is harder. Ben and Maya cover brainstorming, affinity diagrams, multivoting, nominal group technique, prioritization matrices, and consensus while showing how to select the correct team tool for an exam scenario.
A technically perfect solution can still fail when the people affected by it refuse to adopt it. Ben and Maya explore stakeholder engagement, resistance to change, communication, participation, and why lasting improvement requires both technical quality and human acceptance.
