IASSC publishes no percentage weights. It states the exam draws approximately 20 questions from each of the five Body of Knowledge sections, so all five DMAIC phases carry equal weight. This bank mirrors that exactly: 50 questions per phase, no editorial re-weighting. Note that equal weighting does not mean equal breadth - Improve has 8 sub-topics against Analyze's 20 - so the Improve phase is probed far more deeply per topic, and this bank follows that same shape. These are independent original practice questions, not IASSC or PeopleCert exam content.
