Key takeaways
- Track a small set of KPIs that link plan, execution and quality.
- Schedule adherence tells you whether the plan is trusted.
- OEE tells you where capacity is lost.
The seven KPIs
| KPI | Formula | Why it matters |
|---|---|---|
| Schedule adherence | Jobs completed as planned ÷ jobs planned | Measures plan quality and discipline |
| On-time delivery (OTD) | Orders shipped on time ÷ orders shipped | The customer's view of your plant |
| OEE | Availability × Performance × Quality | Shows where capacity is lost |
| Changeover time | Average minutes between last good and first good part | Direct lever on capacity |
| First-pass yield | Good units first time ÷ units started | Quality at the source |
| Downtime by reason | Minutes per reason code | Targets improvement work |
| Plan stability | % of schedule changed inside the frozen window | Signals firefighting |
Making KPIs useful
KPIs only drive action when they are timely and drillable. If OEE drops, you should be able to click through to the line, the shift, the work order and the downtime reason in seconds — that is what a single data model makes possible.
