SOP Review Cycle Time at 35% revision and re-approval overhead: a worked example

This scenario runs the sop review cycle time calculation on the strong side: 35% revision and re-approval overhead, with every other input held at its documented default. Use this when planning annual or semi-annual document review cycles, scheduling SME time for procedure reviews, or estimating the documentation team's workload for the upcoming quarter.

The inputs for this scenario

  • SOPs due for periodic review: 40 procedures (unchanged)
  • Average review time per SOP: 2 hr / procedure (unchanged)
  • Revision and re-approval overhead: 35 % (raised for this scenario; the documented default is 30)

Working through the calculation

  • Applying the documented formula (Base review hours = SOPs due x average review time per SOP) to the inputs above produces each figure below.
  • At this operating point the engine returns 27 hr for total sop review cycle hours, the number this scenario is built around.
  • At this operating point the engine returns 20 hr for base review hours (assessment only).
  • At this operating point the engine returns 35 % for revision and re-approval hours added.
  • At this operating point the engine returns 2 pieces / min for sops reviewed per hour.

How this compares with the baseline

  • Against the tool's baseline example, where revision and re-approval overhead sits at 30% and the headline result is 26 hr, this scenario comes in 3.85% above the baseline at 27 hr.
  • Use it when planning a document control cycle, leveling review work so SOPs don't all come due at once, or checking if your quality team can clear the backlog before due dates. 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 SOP review cycle hours: 27 hr (headline result)
  • Base review hours (assessment only): 20 hr
  • Revision and re-approval hours added: 35 %
  • SOPs reviewed per hour: 2 pieces / min
