Engineering Quote Burden at 65% engineering availability for quoting: a worked example

This worked example runs the engineering quote burden numbers for a tougher week than the baseline: 65% engineering availability for quoting instead of the typical 90%. Estimate engineering hours consumed by technical quote reviews.

The inputs for this scenario

  • Engineering hours per technical RFQ: 2.8 hr / RFQ (held at the documented default)
  • Technical RFQs requiring engineering review: 22 RFQs (held at the documented default)
  • Engineering availability for quoting: 65 % (the input this scenario stresses; the baseline uses 90)
  • Quote reuse and confidence factor: 85 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: gross engineering quote hours requested = engineering hours per technical rfq × technical rfqs requiring engineering review.
  • usable engineering quote hours works out to 34.03 hr at these inputs, and this is the headline figure for the scenario.
  • gross engineering quote hours requested works out to 61.6 hr at these inputs.
  • engineering hours lost to limited availability works out to 21.56 hr at these inputs.
  • engineering hours at risk from uncertainty works out to 6.01 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where engineering availability for quoting sits at 90% and the headline result is 47.12 hr, this scenario comes in 27.78% below the baseline at 34.03 hr.
  • Use it during quoting-capacity planning, when a wave of technical RFQs lands and you need to know whether engineering can review them without delaying production work. 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

  • usable engineering quote hours: 34.03 hr (headline result)
