The purpose of this activity is to install and test the system, either in its entirety or in groups of sub-systems. As such, this activity represents parallel testing within the system.  

OVERVIEW

The first important step in this process is the installation of the data base. If a totally new system, this may simply represent initialization of files. However, in most situations, this will include the execution of special data conversion sub-systems to migrate data from an old file format to a new format. This highlights an important point: As a general rule, file management sub-systems should be implemented before output reporting sub-systems. Specifically, sub-systems dealing with file initialization, repair, backup/recovery, data conversion, etc. should be implemented before others.

Test data is assembled to perform the system test. This includes test data derived from the various Phase 7, Sub-System Tests.

Phase 8 represents the last major test of the system prior to putting it into production. As such, testing at this level is performed according to the end-user documentation. This specifically includes the various Administrative Procedure Manuals and Computer Run Books. Because of this, end-users and DP Operations should be invited to participate in the system test. This can be combined and made a part of the user's education/training (Activity B).  

STEPS IN EXECUTION

1. Systems Engineering prepares a Detail estimate and schedule for the Activities of Phase 8 (A through C).

2. Systems Engineering instructs Data Base Administration to install the data base.

3. Systems Engineering retrieves copies of the Administrative Procedure Manuals and Computer Run Books.

4. Systems Engineering assembles the test data from the various Phase 7's.

5. Systems Engineering performs a parallel test of all of the sub-systems in the system. Software Engineering and Data Base Administration participate in the test accordingly. Corrections are implemented as required.
