QMS, CAPA & Quality System Management worked example

Change Control Workload at 12% impact-assessment and approval-routing allowance: a worked example in qms, capa & quality system management

Push impact-assessment and approval-routing allowance up to 12% and the picture changes. This example computes every intermediate figure at that operating point. Use it when change control workload in qms, capa and quality system management is changing rate or allowance and you want to see the impact.

The inputs for this scenario

  • Change requests queued for processing: 120 units (unchanged)
  • Change requests fully processed per minute: 12 units / min (unchanged)
  • Impact-assessment and approval-routing allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base change control workload time = change control workload workload รท change control workload completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required change control workload time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base change control workload time.
  • At this operating point the engine returns 12 % for change control workload allowance applied.
  • At this operating point the engine returns 12 pieces / min for change control workload completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where impact-assessment and approval-routing allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • It converts a queue of change requests and a per-minute processing rate into base hours, then adds an impact-assessment and routing allowance to give required workload time. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Required change control workload time: 11.2 hr (headline result)
  • Base change control workload time: 10 hr
  • Change control workload allowance applied: 12 %
  • Change control workload completion rate: 12 pieces / min
