The cost committed by the end of conceptual design is

  • A.Equal to the amount spent so far
  • B.Impossible to estimate
  • C.Most of the total, though little is spent
  • D.Negligible, since nothing has been built

Answer: C

Correct answer: Most of the total, though little is spent

By the end of conceptual design perhaps five per cent of the programme budget has been spent, but the configuration chosen - number of engines, layout, materials, technology level - determines something like two thirds of the lifetime cost of development, manufacture and support. Later phases refine within those choices rather than reopening them. This mismatch between spend and commitment is why so much analytical effort is justified so early, when changes are still nearly free.
