derived requirement

Abbreviation(s) and Synonym(s):

None

Definition(s):

  A requirement that is implied or transformed from a higher-level requirement. Note 1: Implied requirements cannot be assessed since they are not contained in any requirements baseline. The decomposition of requirements throughout the engineering process makes implicit requirements explicit, allowing them to be stated and captured in appropriate baselines and allowing associated assessment criteria to be stated. Note 2: A derived requirement must trace back to at least one higher-level requirement.
