Engineering Data Latency Cost at 40% share of delayed changes that reach production: a worked example

This worked example runs the engineering data latency cost numbers for a tougher week than the baseline: 40% share of delayed changes that reach production instead of the typical 55%. Estimates the cost of stale or slow-propagating engineering data disrupting downstream production and procurement.

The inputs for this scenario

  • Engineering changes delayed by slow data per year: 320 changes (held at the documented default)
  • Cost per day a change sits delayed: 180 $/change (held at the documented default)
  • Share of delayed changes that reach production: 40 % (the input this scenario stresses; the baseline uses 55)
  • Fixed expedite and scrap baseline: 9,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Latency cost = delayed changes x cost per delay x production-impact share + expedite baseline.
  • Total engineering data latency cost works out to 32,040 $ at these inputs, and this is the headline figure for the scenario.
  • Engineering data latency cost per unit works out to 100 $ / piece at these inputs.
  • Variable engineering data latency cost works out to 23,040 $ at these inputs.
  • Fixed engineering data latency cost adder works out to 9,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of delayed changes that reach production sits at 55% and the headline result is 40,680 $, this scenario comes in 21.24% below the baseline at 32,040 $.
  • Use it when justifying PLM, digital-thread, or data-integration investment, or benchmarking latency cost before and after a process change. 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

  • Total engineering data latency cost: 32,040 $ (headline result)
  • Engineering data latency cost per unit: 100 $ / piece
  • Variable engineering data latency cost: 23,040 $
  • Fixed engineering data latency cost adder: 9,000 $
