Detailed Exam Domain CoverageThis practice test course is explicitly structured around the official Lean Six Sigma Green Belt Certification syllabus. The questions reflect the exact weightings and scenario-based complexity you will face during the actual 60-question, 90-minute open-book exam.Define Phase & Problem Definition (25% of the exam)Core Focus: Project charter creation, identifying business cases, and translating the Voice of the Customer (VOC) into measurable requirements.Key Tools: SIPOC diagram development, CTQ (Critical to Quality) identification, and problem statement formulation.Measure Phase & Data Collection (25% of the exam)Core Focus: Establishing process baselines, determining data collection plans, and ensuring measurement accuracy.Key Tools: Selecting appropriate measurement systems, process mapping & flowcharting, basic statistical tools (mean, median, mode, range), and Measurement System Analysis (MSA) concepts (Gage R&R).Analyze Phase & Root Cause Analysis (25% of the exam)Core Focus: Analyzing data and process flows to isolate the true root causes of defects, waste, and variation.Key Tools: Pareto analysis and the 80/20 principle, cause-and-effect (fishbone) diagrams, hypothesis testing basics, along with simple regression and correlation analysis.Improve & Control Phases & Implementation (25% of the exam)Core Focus: Developing data-driven solutions, implementing changes, and setting up mechanisms to sustain those gains over time.Key Tools: Design of Experiments (DOE) fundamentals, Lean tools (5S, Kaizen, Poka-Yoke), control charts (SPC), process capability indices (Cp, Cpk), and standard work/sustai
