Green, green, green… late
For three months, every robot cell status report was green. Then, two weeks before FAT, the team announced a four-week delay.
Looking back, the signs were there: CPI drifting down from 0.99 to 0.91, wiring progress stuck at “90%” for weeks, defects increasing. Each number alone looked acceptable. Nobody looked at the trend, and nobody compared progress with the plan objectively.
Monitoring is not collecting numbers. It is comparing, analysing, forecasting and acting early.
