The purpose of this activity is to test the sub-system for procedural conformity and to assure the correct processing of data.  

OVERVIEW

This activity tries to simulate live conditions. In addition to verifying the processing of data, Systems Engineering assures that there is a smooth flow of work between people and equipment. Procedural "bottle-necks" are identified and expedited.

Using the data prepared in Activity A, Systems Engineering tests the sub-system for normal operation. All program errors found are corrected by Software Engineering. Test data used in Phases 5 and 6 should be revised to detect these errors.

Sub-system testing is considered complete when it can handle all test data correctly and meets environmental operating specifications.

In addition to Systems Engineering and Software Engineering, Data Base Administration and DP Operations may participate in the test.  

STEPS IN EXECUTION

1. Systems Engineering tests the sub-system until all logic errors have been eliminated.

2. Systems Engineering retains the test data and test results for review in the next activity. If necessary, Software Engineering updates the Phase 5 and 6 test data.
