Service Bureau Backlog at 65% backlog conversion probability: a worked example

This worked example runs the service bureau backlog numbers for a tougher week than the baseline: 65% backlog conversion probability instead of the typical 90%. Estimate dollar value tied up in quoted or booked AM backlog from backlog units, average value, probability capture, and fixed backlog burden.

The inputs for this scenario

  • Open backlog jobs or booked print hours: 34 jobs or hr (held at the documented default)
  • Average value per backlog job: 720 $ / job or $ / hr (held at the documented default)
  • Backlog conversion probability: 65 % (the input this scenario stresses; the baseline uses 90)
  • Backlog coordination and scheduling burden: 600 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Captured backlog value = backlog jobs or hours × average backlog value × probability/capture.
  • Service bureau backlog value works out to 16,512 $ at these inputs, and this is the headline figure for the scenario.
  • Average backlog value works out to 486 $ / job or $ / hr at these inputs.
  • Captured backlog value works out to 15,912 $ at these inputs.
  • Backlog coordination burden works out to 600 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where backlog conversion probability sits at 90% and the headline result is 22,632 $, this scenario comes in 27.04% below the baseline at 16,512 $.
  • Use it for monthly capacity planning, investment decisions, or whenever you need to report committed pipeline value to ownership or a lender. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Service bureau backlog value: 16,512 $ (headline result)
  • Average backlog value: 486 $ / job or $ / hr
  • Captured backlog value: 15,912 $
  • Backlog coordination burden: 600 $
