QMS, CAPA & Quality System Management worked example
Preventive Action Payback with upfront cost of the preventive action of 62,500 $: a worked example
Push upfront cost of the preventive action up to 62,500 $ and the picture changes. This example computes every intermediate figure at that operating point. Use it when preventive action payback in qms, capa and quality system management is being put in front of a capital committee and the savings story needs to hold up.
The inputs for this scenario
- Upfront cost of the preventive action: 62,500 $ (raised for this scenario; the documented default is 25,000)
- Annual savings from avoided failures and rework: 18,000 $ / yr (unchanged)
- Annual cost to sustain the preventive control: 2,500 $ / yr (unchanged)
Working through the calculation
- Applying the documented formula (Net annual preventive action payback savings = annual preventive action payback savings - annual preventive action payback support cost) to the inputs above produces each figure below.
- At this operating point the engine returns 4.03 yr for preventive action payback payback period, the number this scenario is built around.
- At this operating point the engine returns 15,500 $ / yr for net annual preventive action payback savings.
- At this operating point the engine returns 62,500 $ for preventive action payback investment.
- At this operating point the engine returns 15,000 $ for five-year net preventive action payback value.
How this compares with the baseline
- Against the tool's baseline example, where upfront cost of the preventive action sits at 25,000 $ and the headline result is 1.61 yr, this scenario comes in 150% above the baseline at 4.03 yr.
- It computes the payback period in years by dividing the preventive action investment by the net annual savings (gross savings minus the annual cost to keep the control running). 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.
