GSE Field Service Reserve at 92% covered field service event share: a worked example

Push covered field service event share up to 92% and the picture changes. This example computes every intermediate figure at that operating point. a fleet maintenance or service manager needs to budget field service support for deployed GSE units

The inputs for this scenario

  • Expected GSE field service events: 85 events (unchanged)
  • Cost per field service event: 740 $ / event (unchanged)
  • Covered field service event share: 92 % (raised for this scenario; the documented default is 80)
  • Fixed travel and support reserve: 18,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Covered field service event cost = expected field service events × cost per event × covered event share) to the inputs above produces each figure below.
  • At this operating point the engine returns 75,868 $ service reserve for total field service reserve, the number this scenario is built around.
  • At this operating point the engine returns 893 $ / piece for cost per field service event.
  • At this operating point the engine returns 57,868 $ for covered field service event cost.
  • At this operating point the engine returns 18,000 $ for fixed travel and support reserve.

How this compares with the baseline

  • Against the tool's baseline example, where covered field service event share sits at 80% and the headline result is 68,320 $ service reserve, this scenario comes in 11.05% above the baseline at 75,868 $ service reserve.
  • It computes the total dollars to reserve for GSE field service by combining covered event costs with a fixed travel and support base. 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 field service reserve: 75,868 $ service reserve (headline result)
