Industrial Training, Documentation & Work Instructions worked example

Work Instruction Creation Load at 29% review, revision, and approval allowance: a worked example

This scenario runs the work instruction creation load calculation on the strong side: 29% review, revision, and approval allowance, with every other input held at its documented default. Use this when planning a documentation project for a new product launch, process change, or compliance initiative where multiple work instructions need to be written within a fixed timeline.

The inputs for this scenario

  • Work instructions to create: 25 documents (unchanged)
  • Average authoring time per instruction: 8 hr / document (unchanged)
  • Review, revision, and approval allowance: 29 % (raised for this scenario; the documented default is 25)

Working through the calculation

  • Applying the documented formula (Base authoring hours = number of work instructions x average authoring time per instruction) to the inputs above produces each figure below.
  • At this operating point the engine returns 4.03 hr for total work instruction creation hours, the number this scenario is built around.
  • At this operating point the engine returns 3.13 hr for base authoring hours.
  • At this operating point the engine returns 29 % for review and approval hours added.
  • At this operating point the engine returns 8 pieces / min for authoring rate (documents per hour).

How this compares with the baseline

  • Against the tool's baseline example, where review, revision, and approval allowance sits at 25% and the headline result is 3.91 hr, this scenario comes in 3.2% above the baseline at 4.03 hr.
  • Use it when planning a documentation effort for a launch, line change, or audit, to staff and schedule the work. 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

  • Total work instruction creation hours: 4.03 hr (headline result)
