1.1 General
This International Standard makes recommendations for the implementation of design review
as a means of verifying that the design input requirements have been met and stimulating the
improvement of the product’s design. The intention is for it to be applied during the design
and development phase of a product’s life cycle.
It provides guidelines for planning and conducting a design review and specific details
concerning contributions by specialists in reliability, maintenance, maintenance support and availability.
1.2 Application
The stage or stages at which a design review is to be performed should be determined in the
design and development planning stage of a project or a design task. Influencing factors
should include customer requirements, regulatory requirements, the size and complexity of
the product, the use to which the product is to be put, and the consequences of failure.
The cost to correct deficiencies in a design and the potential consequences increase as the
design nears completion. Also, as the design progresses towards completion, so the flexibility
to implement a change to correct a deficiency or to optimize the design decreases.
1.3 Types of application
There are two types of application: either an in-house created requirement for a new design,
or a design requirement from an external source. In the case of the latter, the risk of a
misunderstanding is much greater. Any misunderstanding could become a contractual issue
and design review meetings with the client will be of primary importance to ensure that the
emerging design meets the client's requirements.
