Estimator Workload Capacity at 65% estimator productive-time fraction: a worked example

Suppose estimator productive-time fraction falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate workload capacity for manufacturing sales engineering, estimating and quoting operations using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Quotes completed per estimating session: 4 units / cycle (held at the documented default)
  • Available estimating sessions in period: 480 cycles (held at the documented default)
  • Estimator productive-time fraction: 65 % (the input this scenario stresses; the baseline uses 90)
  • Quotes accepted without rework: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross workload capacity = workload capacity output per cycle × available workload capacity cycles.
  • Good workload capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross workload capacity works out to 1,920 units at these inputs.
  • Workload capacity downtime loss works out to 672 units at these inputs.
  • Workload capacity yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where estimator productive-time fraction sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
  • It computes good (usable, first-pass-clean) quote capacity by applying a productive-time fraction and a first-pass acceptance rate to gross quoting throughput. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
