IEC 61160-2005 pdf – Revue de conception Design review.
The objectives of a design review include: • assessing whether the proposed solution meets the design input requirements that include, but are not limited to: specified general performance requirements, dependability, lifecycle costs, safety, endurance, environment, electromagnetic compatibility, human factors; • assessing whether the proposed solution is the most robust, efficient and effective solution to achieve the product requirements; • providing recommendations as required for achieving the design input requirements; • assessing the status of the design in terms of the completeness of the drawings and specifications; • assessing the evidence to support the verification of the design performance; • proposing improvements. Design review facilitates assessment of the status of the design against the input require- ments, identification of opportunities for improvement and guides the design manager towards appropriate action. It accelerates maturing of the product by reducing the time needed to stabilize design details, and allows product realization to proceed without frequent interruptions. Design review can also stimulate early product improvement. 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.
The design review should be incorporated into the organization’s overall management system and, as applicable, each project’s schedule. Limitations of size and resources of the organization, project value, product benefits, risks and complexity, all influence the size and frequency of design reviews. In smaller organizations, it could be necessary to supplement staff with personnel from suppliers, consultants and other outside advisors. 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.
A design review should be held: • prior to order acceptance to ensure that the scope of work is established together with all the parameters that need to be met for an acceptable design; • prior to detail design to ensure that the members of the design team have first-hand knowledge of all detail requirements. Interface provisions should be established and a list of defining documentation scheduled for submission and approval between the parties; • at suitable points during detail design to review all interface provisions and agree on the test procedures for verifying that the design meets contract requirements. 2 Normative references The following referenced documents are indispensable for the application of this document.

NOTE 2 A qualifier can be applied to indicate the nature of what is being designed and developed (e.g. product design and development or process design and development).
