GMP Audit Load with gmp audits or audit items of 50 audits: a worked example

Suppose gmp audits or audit items falls to 50 audits. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate GMP audit workload from audit count, hours per audit, and available auditor capacity.

The inputs for this scenario

  • GMP audits or audit items: 50 audits (the input this scenario stresses; the baseline uses 100)
  • Hours per audit or item: 1.2 hr / audit (held at the documented default)
  • Available auditor hours: 8 hr (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Required workload = GMP audits or audit items × Hours per audit or item.
  • Total load works out to 60 hr at these inputs, and this is the headline figure for the scenario.
  • Hourly equivalent works out to 7.5 hr / hr at these inputs.
  • Input load works out to 50 hr at these inputs.
  • Load factor works out to 1.2 x at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where gmp audits or audit items sits at 100 audits and the headline result is 120 hr, this scenario comes in 50% below the baseline at 60 hr.
  • It computes total required audit workload in hours and the ratio of that workload to available auditor hours. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Total load: 60 hr (headline result)
  • Hourly equivalent: 7.5 hr / hr
  • Input load: 50 hr
  • Load factor: 1.2 x
