Schedule Attainment

A planning-adherence KPI. Distinct from throughput efficiency when “scheduled” is the firm plan rather than an engineered target rate.

Attainment % = actual completed ÷ scheduled quantity × 100.

Tip: Keep “Actual Completed” and “Scheduled Quantity” on the same basis (period, units, and population) before calculating Schedule Attainment.

Schedule attainment measures how much of the planned schedule was actually completed.

Enter actual completed quantity and scheduled quantity for the same period.

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

Schedule Attainment
Attainment % = (Actual completed ÷ Scheduled) × 100

Worked Example

Scenario: Actual 9,400; scheduled 10,000.
Step 1: 9400 ÷ 10000 = 0.94
Step 2: × 100 = 94%
Answer: Schedule attainment is 94%.

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.
