Traceability defined as the ability to trace dependent items within a
model and the ability to trace correspondent items in other models is
advocated as a desirable property of a software development process. P
otential benefits of good traceability are clearer documentation, more
focussed development, increased ease of system understanding, and mor
e precise impact analysis of proposed changes, An industry-scale proje
ct applying the analysis and design method Objectory has been examined
and documented with a number of traceability examples generated from
the perspective of a maintainer attempting to understand the system, F
our representative examples and a categorization of traceability are p
resented in this study in order to provide a concrete empirical basis
for the application of traceability to systems development.
