AS IEC 61160 pdf download – Design review
The objectives of a design review include:
assessing whether the proposed solution meets the design input requirements thatinclude, but are not limited to: specified general performance requirements,dependability,lifecycle costs,safety,endurance,environment,electromagnetic compatibility,humanfactors;
assessing whether the proposed solution is the most robust,efficient and effectivesolution 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 andspecifications;
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 towardsappropriate action. It accelerates maturing of the product by reducing the time needed tostabilize design details,and allows product realization to proceed without frequentinterruptions.Design review can also stimulate early product improvement.
The stage or stages at which a design review is to be performed should be determined in thedesign and development planning stage of a project or a design task. Influencing factorsshould include customer requirements,regulatory requirements, the size and complexity ofthe 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 thedesign nears completion.Also, as the design progresses towards completion, so the flexibilityto implement a change to correct a deficiency or to optimize the design decreases.
Each organization undertaking design and development should adopt either a comprehensivedesign review programme as presented in this standard, or tailor a more limited one to meetspecific product andior process needs.
The design review should be incorporated into the organization’s overall management systemand, as applicable, each project’s schedule.
Limitations of size and resources of the organization,project value,product benefits,risksand complexity,all influence the size and frequency of design reviews. In smallerorganizations, it could be necessary to supplement staff with personnel from suppliers,consultants and other outside advisors.
1.3Types 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 amisunderstanding is much greater. Any misunderstanding could become a contractual issueand design review meetings with the client will be of primary importance to ensure that theemerging design meets the clients requirements.
A design review should be held:
prior to order acceptance to ensure that the scope of work is established together with allthe 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-handknowledge of all detail requirements. Interface provisions should be established and a listof defining documentation scheduled for submission and approval between the parties;at suitable points during detail design to review all interface provisions and agree on thetest procedures for verifying that the design meets contract requirements.

3Terms and definitions
For the purposes of this document the terms and definitions of IEC 60050(191) apply,together with the following additional definitions.
action item
question to be resolved by the design manager or nominated person3.2
activity undertaken to determine the suitability, adequacy and effectiveness of the subjectmatter to achieve established objectives

NOTE 1 The terms “design”and “development”are sometimes used synonymously and sometimes used to definedifferent stages of the overall design and development process.
NOTE 2 A qualifier can be applied to indicate the nature of what is being designed and developed (e.g.productdesign and development or process design and development).
