Manufacturing Project Portfolio & Capex worked example

Project Margin Impact with available project margin after the change of 310 value: a worked example

What does the result look like when available project margin after the change reaches 310 value? The full calculation is worked below with real intermediate numbers. Use it when project margin impact in manufacturing project portfolio and capex needs a clean margin number for a manufacturing project portfolio and capex go / no-go review.

The inputs for this scenario

  • Available project margin after the change: 310 value (raised for this scenario; the documented default is 125)
  • Required project margin to break even: 100 value (unchanged)
  • Reference baseline margin: 100 value (unchanged)

Working through the calculation

  • Applying the documented formula (Project margin impact amount gap = available project margin impact amount - required project margin impact amount) to the inputs above produces each figure below.
  • At this operating point the engine returns 210 % for project margin impact margin, the number this scenario is built around.
  • At this operating point the engine returns 210 value for project margin impact amount gap.
  • At this operating point the engine returns 310 value for available project margin impact amount.
  • At this operating point the engine returns 100 value for required project margin impact amount.

How this compares with the baseline

  • Against the tool's baseline example, where available project margin after the change sits at 125 value and the headline result is 25 %, this scenario comes in 740% above the baseline at 210 %.
  • A figure at this level is achievable when available project margin after the change is genuinely sustained, not just peaked for a shift. The result is only as meaningful as the reference amount you choose; a poorly chosen baseline can make a trivial change look large or hide a real one.

Results at a glance

  • Project margin impact margin: 210 % (headline result)
  • Project margin impact amount gap: 210 value
  • Available project margin impact amount: 310 value
