QMS, CAPA & Quality System Management worked example

Audit Evidence Completeness at 99% auditor availability factor: a worked example

What does the result look like when auditor availability factor reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when audit evidence completeness in qms, capa and quality system management is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Records gathered per audit cycle: 4 units / cycle (unchanged)
  • Audit cycles available in window: 480 cycles (unchanged)
  • Auditor availability factor: 99 % (raised for this scenario; the documented default is 90)
  • Records passing review first time: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross audit evidence completeness capacity = audit evidence completeness output per cycle × available audit evidence completeness cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good audit evidence completeness capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross audit evidence completeness capacity.
  • At this operating point the engine returns 19.2 units for audit evidence completeness downtime loss.
  • At this operating point the engine returns 57.02 units for audit evidence completeness yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where auditor availability factor sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • A figure at this level is achievable when auditor availability factor is genuinely sustained, not just peaked for a shift. It models throughput, not coverage — hitting the record count doesn't guarantee every clause or process area is represented, so map evidence to requirements separately.

Results at a glance

  • Good audit evidence completeness capacity: 1,844 units (headline result)
  • Gross audit evidence completeness capacity: 1,920 units
  • Audit evidence completeness downtime loss: 19.2 units
  • Audit evidence completeness yield loss: 57.02 units
