Software development standards demand requirements
traceability without being explicit about the appropriate
level of quality of trace links. Unfortunately,
long-term trace utilizations are typically unknown at
the time of trace acquisition which represents a dilemma
for many companies. This paper suggests ways
to balance the cost and benefits of requirements traceability.
We present data from 3 case studies. Lessons
learned suggest a traceability strategy that (1) provides
trace links more quickly, (2) refines trace links
according to user-definable value considerations, and
(3) supports the later refinement of trace links in case
the initial value considerations change.
