Fixture, Gauge & Workholding Management worked example

Fixture Design Workload at 21% review, eco, and tryout allowance: a worked example

This scenario runs the fixture design workload calculation on the strong side: 21% review, eco, and tryout allowance, with every other input held at its documented default. Use it when planning tooling engineer capacity, fixture design queues, launch support, or outsourced design packages.

The inputs for this scenario

  • Fixture designs or revisions: 26 designs (unchanged)
  • Completed designs per engineering hour: 1.5 designs / hr (unchanged)
  • Review, ECO, and tryout allowance: 21 % (raised for this scenario; the documented default is 18)

Working through the calculation

  • Applying the documented formula (Base fixture design workload time = fixture designs or revisions รท completed designs per engineering hour) to the inputs above produces each figure below.
  • At this operating point the engine returns 20.97 hr for required fixture design workload time, the number this scenario is built around.
  • At this operating point the engine returns 17.33 hr for base fixture design workload time.
  • At this operating point the engine returns 21 % for review, eco, and tryout allowance.
  • At this operating point the engine returns 1.5 designs / hr for completed designs per engineering hour.

How this compares with the baseline

  • Against the tool's baseline example, where review, eco, and tryout allowance sits at 18% and the headline result is 20.45 hr, this scenario comes in 2.54% above the baseline at 20.97 hr.
  • Use it when staffing a fixture design program, building a deliverables schedule, or quoting engineering hours for a tooling package. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Required fixture design workload time: 20.97 hr (headline result)
