Test Cycle Duration at 14% test setup and retest allowance: a worked example

This worked example runs the test cycle duration numbers for a tougher week than the baseline: 14% test setup and retest allowance instead of the typical 20%. Estimate hydraulic, functional, or final test time for construction attachments.

The inputs for this scenario

  • Test points or functions to verify: 64 checks (held at the documented default)
  • Test completion pace: 7.5 checks / hr (held at the documented default)
  • Test setup and retest allowance: 14 % (the input this scenario stresses; the baseline uses 20)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base functional test time = test points or functions to verify รท test completion pace.
  • estimated test cycle duration works out to 9.73 hr at these inputs, and this is the headline figure for the scenario.
  • base functional test time works out to 8.53 hr at these inputs.
  • test setup and retest allowance works out to 14 % at these inputs.
  • test completion pace works out to 7.5 checks / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where test setup and retest allowance sits at 20% and the headline result is 10.24 hr, this scenario comes in 5% below the baseline at 9.73 hr.
  • Use it when scheduling test-stand time for a new attachment build or quoting validation effort for a custom unit. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • estimated test cycle duration: 9.73 hr (headline result)
  • base functional test time: 8.53 hr
  • test setup and retest allowance: 14 %
  • test completion pace: 7.5 checks / hr
