The design review provides a forum in which questions can be answered, assumptions clarified and advice sought. They are a useful mechanism whereby the design of a product can be optimized through a systematic review of and feedback on design process outputs. Typically, a number of formal and informal reviews are conducted during the duration of a design project phase.
The objectives of a design review are to ensure that all contributory factors and reasonable design options have been considered, and that the design meets the requirements as outlined in the Product Development Specification. The design team are responsible for providing an accurate, concise overview of the design to-date and the facilitation of productive discussions. Reviewers are responsible for assessing the design to ensure that it can be produced, tested, installed, operated and maintained in a manner that is acceptable to the customer.
Design Review Types:
Often, different types of reviews are combined into a single review. The following provides a sample of the different design reviews that can be conducted:
• Requirements Review: is conducted to ensure that all of the appropriate requirements and constraints have been clearly and completely identified.
• System Design Review: In the case of large systems being developed, a system design review examines the allocation of requirements to individual configuration items.
• Preliminary Design Review: Design concepts are evaluated for feasibility, technical adequacy and general compliance with requirements, and the relative merits/weaknesses of different concepts are presented.
• Critical Design Review: is an intermediate design review that occurs after the detail design is complete and prior to the fabrication of prototypes or pre-production models.
• Test Readiness Review: that will be applied to prototypes or pre-production units to verify the design against the requirements. These plans are reviewed for reliability and completeness.
• Final Design Review: is conducted after prototypes or preproduction units have been through verification testing. Problems encountered during this testing and the respective solutions are examined.
• Production Readiness Review: A number of PRRs are held through the development of a product and are not usually tied to other design reviews.
• Ad Hoc Reviews: Problems may arise during the course of the project that may drastically change the direction of the design. In such situations, it may be appropriate to call a design review in order obtain multidisciplinary input before proceeding with critical decisions.
Design Review Team:
The key participants at a design review include the Chairperson, the design team, subject
matter experts and the customer.
Design Review Conducting:
For all of the reviewers you should confirm that will have a full understanding of all of the aspects of the design background or technology and be sure to take suggestions and comments seriously, as they may in fact help you in your development.to get the optimum results.
Design Review Report:
Due to all of items requiring follow-up should have an associated date for completion, the minutes should identify the participants of the meeting and the roles they played and registered to help during various meeting and report creation.
In addition to the meeting minutes, the report should contain the status of each issue or action item as well as the details on the resolution of these items. If further investigation, testing or other analyses have been completed, evidence of these should be furnished.
Benefits of Design Review:
To get optimum benefits from design review, it should schedule in project management plan; some of benefits are:
- Early detection for customer satisfaction.
- Incentives for investment control/reduction.
- Reduced Work during testing.
- Reduced errors in maintenance.
Finally, the earlier in the design process that errors are identified, the less costly they are to correct (Boehm 1985).
