Traceability (EBT) requirements are seen as publishers of change events
and dependent entities as subscribers. When a significant change
occurs in the requirements specification, all subscribers are notified
of the change. Using an event-notification architecture enables
the EBT traceability scheme to handle change robustly.
EBT offers these
management: EBT manages the requirements evolution process
by monitoring user's actions on the requirements specification and
identifying significant and managable change events.
Traceability - EBT supports "just-in-time" traceability
that enables links to be restored and entities updated to reflect
changes even if developer failes to update all of the traceability
links at the time of making the change.
