Vending, Kiosk & Self-Service Equipment worked example

Rework Cost at 9.2% share of kiosks sent to rework: a worked example in vending, kiosk & self-service equipment

Push share of kiosks sent to rework up to 9.2% and the picture changes. This example computes every intermediate figure at that operating point. A production engineer quantifies expected rework on a kiosk build to justify upstream fixes to wiring, vend mechanisms, or panel fit.

The inputs for this scenario

  • Kiosks built in the period: 400 machines (unchanged)
  • Rework labor plus parts per reworked kiosk: 145 $/machine (unchanged)
  • Share of kiosks sent to rework: 9.2 % (raised for this scenario; the documented default is 8)
  • Fixed rework bay setup cost: 5,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Rework Cost = Machines Built x Rework Labor+Parts x Rework Incidence% + Rework Bay Setup) to the inputs above produces each figure below.
  • At this operating point the engine returns 10,336 $ for total rework cost, the number this scenario is built around.
  • At this operating point the engine returns 25.84 $ / piece for rework cost per unit.
  • At this operating point the engine returns 5,336 $ for variable rework cost.
  • At this operating point the engine returns 5,000 $ for fixed rework cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where share of kiosks sent to rework sits at 8% and the headline result is 9,640 $, this scenario comes in 7.22% above the baseline at 10,336 $.
  • It computes total rework cost as reworked-kiosk volume times per-machine rework cost plus a fixed bay setup, and divides by machines built for a per-unit figure. 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

  • Total rework cost: 10,336 $ (headline result)
  • Rework cost per unit: 25.84 $ / piece
  • Variable rework cost: 5,336 $
  • Fixed rework cost adder: 5,000 $
