Step 1: Measure before changing
Capture two weeks of baseline event timelines across target docks.

Step 2: Segment delays
Classify delay into pre-load wait, active-load interruption, and post-load dwell.
Step 3: Target highest-impact delays
Rank by frequency x duration x business impact.

Step 4: Validate improvement
Use the same event model post-change. Compare median and p90 cycle-time values to baseline.
