Understanding Schedule Attainment
How we calculate. Attainment % = actual completed ÷ scheduled quantity × 100. The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.
Real-world scenario: A typical Schedule Attainment case uses actual completed 9400 and scheduled quantity 10000. Enter the same figures below to reproduce the worked path.
What is Schedule Attainment?
A planning-adherence KPI. Distinct from throughput efficiency when “scheduled” is the firm plan rather than an engineered target rate.
- Same UOM for actual and scheduled
- Freeze the schedule snapshot
- Can exceed 100% if overbuilt
The Formula
Worked Example
Common Use Cases
- MRP/MES: plan vs actual
- Customer OTIF root cause: make-complete
- Shift scorecards: schedule hit rate
Pro Tips
- Don’t silently change the plan mid-shift
- Segment by constraint resource
- Pair with OEE and downtime
Limitations: Schedule Attainment results are educational manufacturing and lean/TPM planning aids—not process-safety, quality-system, or financial advice. Confirm definitions with your MES/SCADA and quality policies.
FAQ
Different from throughput efficiency?
Throughput efficiency uses a target rate; schedule attainment uses the firm scheduled quantity for the window.
What if scheduled is 0?
Attainment is undefined—enter a positive scheduled quantity.
