SOP Review Cycle Time at 22% revision and re-approval overhead: a worked example

This worked example runs the sop review cycle time numbers for a tougher week than the baseline: 22% revision and re-approval overhead instead of the typical 30%. Estimate total labor hours required to complete periodic SOP reviews, including the number of procedures due, review time per SOP, and revision and re-approval overhead.

The inputs for this scenario

  • SOPs due for periodic review: 40 procedures (held at the documented default)
  • Average review time per SOP: 2 hr / procedure (held at the documented default)
  • Revision and re-approval overhead: 22 % (the input this scenario stresses; the baseline uses 30)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base review hours = SOPs due x average review time per SOP.
  • Total SOP review cycle hours works out to 24.4 hr at these inputs, and this is the headline figure for the scenario.
  • Base review hours (assessment only) works out to 20 hr at these inputs.
  • Revision and re-approval hours added works out to 22 % at these inputs.
  • SOPs reviewed per hour works out to 2 pieces / min at these inputs.

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 6.15% below the baseline at 24.4 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. 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

  • Total SOP review cycle hours: 24.4 hr (headline result)
  • Base review hours (assessment only): 20 hr
  • Revision and re-approval hours added: 22 %
  • SOPs reviewed per hour: 2 pieces / min
