Discussion

A candidate part meets every criterion but its compiler is available only under an annual licence costing more than the first year's production. The correct response is

  • A.to reject the part immediately on principle
  • B.to use an unlicensed compiler for production builds
  • C.to weigh that licence in the total cost of the selection
  • D.to disregard it, tool costs falling outside the product cost

Answer: C

Correct answer: to weigh that licence in the total cost of the selection

A tool licence is a real and recurring cost of using the part, so it belongs in the comparison alongside the unit price, the development effort and the risk. Sometimes it is worth paying and sometimes another part with a free toolchain wins on the total; that is a calculation rather than a matter of principle. Using an unlicensed compiler for production is not an option.
