Supplier Quality, Development & Audits worked example

Supplier Development ROI with upfront supplier development investment of 62,500 $: a worked example

Push upfront supplier development investment up to 62,500 $ and the picture changes. This example computes every intermediate figure at that operating point. Use it when supplier development roi in supplier quality, development and audits is being put in front of a capital committee and the savings story needs to hold up.

The inputs for this scenario

  • Upfront supplier development investment (engineering, tooling, travel): 62,500 $ (raised for this scenario; the documented default is 25,000)
  • Annual savings from the improvement (scrap, PPM, expedite): 18,000 $ / yr (unchanged)
  • Annual ongoing cost to sustain the improvement: 2,500 $ / yr (unchanged)

Working through the calculation

  • Applying the documented formula (Net annual supplier development roi savings = annual supplier development roi savings - annual supplier development roi support cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 4.03 yr for supplier development roi payback period, the number this scenario is built around.
  • At this operating point the engine returns 15,500 $ / yr for net annual supplier development roi savings.
  • At this operating point the engine returns 62,500 $ for supplier development roi investment.
  • At this operating point the engine returns 15,000 $ for five-year net supplier development roi value.

How this compares with the baseline

  • Against the tool's baseline example, where upfront supplier development investment 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 net annual savings (gross savings minus sustaining cost) and divides the investment by that net to give a payback period in years. 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.
