BUSINESS PURPOSE

The purpose of this activity is to review the results of Phase 2 with Data Resource Management, Systems Resource Management, Project Management, and Data Engineering. The review is used to determine whether the project should continued as proposed, revised or discontinued.

OVERVIEW

This is mainly a technical review in which Systems Engineering presents the ALDBM design. The following points should be stressed in this meeting:

The creation of new Objects is justified by explaining why they are needed to satisfy the Information Requirements and why other existing Objects cannot be used. The rationale behind using existing Objects is also explained.

The creation of new data elements is justified along with the reasons for re-using or not re-using existing data elements.

The ALDBM satisfies the DBEM rules as described in the Phase 2 Narrative.

Systems Engineering should be extremely well prepared. Visual aids should be used to explain and clarify findings.

Copies of the Phase 2 "ALDBM Design Manual" should be distributed to pertinent managers well in advance of the review meeting. This allows the manager ample time to study the report and prepare for the meeting.

The intent of the review meeting is not necessarily to explain each section of the report, but to answer questions and summarize the conclusions. The report, thereby, is the focal point of the meeting.

There are three possible outcomes from the review meeting:

Project approved to proceed as proposed.
Project disapproved.
Revise project based on discussion in meeting.

PROJECT APPROVED

Project Management advises all meeting attendees of the results of the meeting by memo or letter. The project continues according to plan.

PROJECT DISAPPROVED

Project Management discontinues all activity on the project and prepares an audit report as indicated in Phase 6. This will document the disposition of the project. All study material is filed in a project file in the Technical Library for future reference.

REVISE PROJECT

During the review meeting, decisions or discussions may have indicated a project change or revision. Systems Engineering modifies the report as required and establishes another review meeting (if necessary) to consider the revised report.

A final and approved copy of the Phase 2 "ALDBM Design Manual," with the initials or signatures of management, is sent to the Technical Library for filing in the project file.

STEPS IN EXECUTION

Systems Engineering defines the relationships between objects via "Relationship Views." These relationships are depicted using ALDBM Matrices and the ALDBM Diagram.

Data Engineering is consulted as required to resolve problems and relationship conflicts.

Systems Engineering and Project Management review the Project Plan and Project Estimate/Schedule Recap. If necessary, both are updated at this time.

Systems Engineering and Project Management prepares a formal Phase 2 manual, "ALDBM Design Manual."

Quality Assurance reviews the "ALDBM Design Manual" for consistency. Systems Engineering and Project Management implement changes accordingly.

Systems Engineering schedules a Phase 2 review meeting with Data Resource Management and Systems Resource Management. Copies of the "ALDBM Design Manual" are distributed to management prior to the review meeting.
