16 ■ Optimize Quality for Business Outcomes
User Acceptance Test
The User Acceptance Test (UAT) is done by users or their rep-
resentatives on a new or changed information system. If the
system behaves according to their expectations, the user accep-
tance testers approve deploying the system. Cosmetic and
other small changes may still be required as a result of the test,
but the system is considered stable and behaving according to
requirements.
Operational Readiness Test
The Operational Readiness Test is the final phase of testing per-
formed on the prospective production system. This test is
scheduled and conducted as a part of the production go-live
plan. It is to be executed after all other cutover activities are
complete, and prior to any go/no-go considerations. The Oper-
ational Readiness Test Summary Report is the final business
acceptance signoff.
Each test phase requires a particular completeness of the com-
ponents to be tested. These components have to be executed in
a certain sequence, which is synchronized with the progress of
the development team. The test phases are repeated for every
release of the software and they define the software test lifecy-
cle — a parallel process with the SDLC, but the two are also
integrated (Figure 5).
