1.System Requirements Review
This review is an examination of the initial progress during the problem definition stage and of the convergence on a complete system configuration. Test planning and test documentation are begun at this review.
2 • System Design Review
This review occurs when the system definition has reached a point where major system modules can be identified and completely specified along with the corresponding test requirements. The requirements for each major subsystem are examined along with the preliminary test plans. Tools required for verification support are identified at this stage.
3• Preliminary Design Review
This review is a formal technical review of the basic design approach for each major subsystem or module. The revised requirements and preliminary design specifications for each major subsystem and all test plans, procedures and documentation are reviewed at this stage. Development and verification tools are further identified at this stage. Changes in requirements will lead to an examination of the test requirements to maintain consistency.
4• Final Design Review
This review occurs just prior to the beginning of the construction stage. The complete and detailed design specifications for each module and all draft test plans and documentation are examined. Again, consistency with previous stages is reviewed, with particular attention given to determining if test plans and documentation reflect changes in the design specifications at all levels.
5• Final Review
This review determines through testing that the final coded subsystem conforms to the final system specifications and requirements. It is essentially the subsystem acceptance test.
Rules should be followed for all reviews:
1. The product is reviewed, not the producer.
2. Defects and issues are identified, not corrected.
3. All members of the reviewing team are responsible for the results of the review.
Reviews are conducted to utilize the variety of perspectives and talents brought together in a team. The main goal is to identify defects within the stage or phase of the project where they originate, rather than in later test stages; this is referred to as “stage containment.”
As reviews are generally greater than 65 percent efficient in finding defects, and testing is often less than 30 percent efficient, the advantage is obvious. In addition, since defects identified in the
review process are found earlier in the life cycle, they are less expensive to correct.
Another advantage of holding reviews is not readily measurable. That is, reviews are an efficient method of educating a large number of people on a specific product/project in a relatively short period of time. Semiformal reviews are especially good for this, and indeed, are often held for just that purpose.
In addition to learning about a specific product/project, team members are exposed to a variety of approaches to technical issues, a cross-pollination effect. Finally, reviews provide training in and enforce the use of standards, as non conformance to standards is considered a defect and reported as such.
