Partial test repetition based on traceability and analysis of technical
and business risks
Customer or user testing
Beta - early release to both potential and current customers
Pilot - deploy to a subset of users
Parallel - users use both old and new systems simultaneously
Use larger releases. Testing new functions often covers existing
functions. The more new features in a release, the more "accidental"
regression testing.
Emergency patches - these patches are released immediately, and will be
included in future maintenance releases.
