Raytheon successfully completed a test readiness review (TRR) of the DDG-1000 Zumwalt total-ship computing environment software, release seven, which involved 550,000 lines of code.

A Test Readiness Review (TRR) is conducted to determine if the system under review is ready to proceed into formal testing by deciding whether the test procedures are complete and verify their compliance with test plans and descriptions. A TRR is normally conducted before each major test configuration item including hardware and software and provides management with the assurance that a system has undergone a thorough test process and is ready for turnover to the next test phase.
