METHODOLOGY NAVIGATION

A Phase 7 may be performed only after Phase 4-I and Phase 6 have been completed. There is a one-to-one relationship between Phase 7 and a sub-system. As such, the Project Manager may bind the procedure number to the project/phase key. For example:

Phase 7 will then proceed to Phase 8 where it will rejoin other sub-systems and put into production.  

GENERAL DISCUSSION

Testing in Phase 7 is performed in a similar manner as in Phase 6, except at a higher level. Whereas Phase 6 "Software Testing," is performed by Software Engineering for all of the programs within the computer procedure, Phase 7 is performed by Systems Engineering for all of the procedures in the sub-system, both administrative and computer.

During Computer Procedure Design, Software Engineering prepared the computer procedure that will be used by DP Operations. In order to test this procedure, it is recommended that DP Operations actually perform the tests under Software Engineering's direction. In this way, the operating procedures are tested along with the programs used to implement the procedure. Often the operating people will point out areas for procedure improvement.

During Phase 3, Systems Engineering specified a testing criteria for the overall sub-system. This included the validation of input/output processing, along with anticipated transaction volume for the sub-system. Phase 7, therefore, is used to verify the test criteria and benchmarks.

Following Phase 7, the sub-system is essentially ready for operation. However, considerable care should be exercised to avoid a premature installation of the sub-system for day-to-day operation. This situation could cause panic conditions if other parts of the system are not ready. This is why Phase 8 is used to release sub-systems.  

DESCRIPTION OF PHASE ACTIVITIES

Activity A - Prepare Test Data

Systems Engineering prepares a Detail estimate and schedule for the activities of Phase 7 (A through C) which is reviewed with Project Management for approval.

Systems Engineering (the Sub-System Designer) assembles the test data from the previous phases and in accordance with the Test Criteria defined in the Sub-System Design Manual.

Activity B - Test/Debug Sub-System

Systems Engineering tests and debugs the sub-system in its entirety, including all procedures. Software Engineering provides assistance as required.

Activity C - Phase 7 Review

Systems Engineering reviews the test results with the system designer and Quality Assurance for compliance with installation standards, and to assure that the system design requirements are satisfied.
