Measure (DMAIC Phase)

Second phase of Six Sigma DMAIC focused on establishing baseline performance and validating measurement systems. Includes Measurement System Analysis (MSA), data collection planning, calculating process capability (Cp/Cpk), and baseline sigma level. Ensures data used for decisions is reliable and repeatable. Answers 'How good or bad is the current performance?' without jumping to solutions. Similar to A3 Current Condition but with explicit focus on measurement validity and statistical baseline establishment.
