The term product includes capital equipment; infrastructure; consumer durables; consumables; s
25、oftware products. Obsolescence is inevitable and it cannot be avoided, but forethought and careful planning can minimize its impact and its potential high costs. The objective of obsolescence management is to ensure that obsolescence is managed as an integral part of design, development, production
26、and in-service support in order to minimize cost and detrimental impact throughout the product life cycle. Obsolescence presents itself in two ways: the item is no longer suitable for current demands, or the item is no longer available from the original manufacturer, e.g. due to economic constraints
27、. From the users point of view, obsolescence then manifests itself as difficulty in obtaining supplies. If the end-user is the general public, it will be in the interest of the supplier to protect his brand image by having a defined obsolescence policy. Commercial-off-the-shelf (COTS) products and c
28、ustom designed items, e.g. new design tools and new production processes, tend to have a much shorter life in terms of availability and supportability than in the past. With the increased use of commercial items in complex products expecting to have a long life cycle, it has become essential to incl
29、ude obsolescence management within programme plans from the earliest stages. Furthermore environmental considerations have the potential to affect the use of some materials during the life of the product and should be considered from the outset. Obsolescence management is essential to achieve optimu
30、m cost-effectiveness throughout the life cycle of a product. The purpose of this standard is to provide guidance on planning a cost effective obsolescence management process that takes into account essential factors to ensure product life cycle costs are considered and applied. Obsolescence manageme
31、nt should also include the maintenance of the relevant knowledge and skill base sets. Clause 4 provides overview of the process and its relation to others. Clauses 5, 6 and 8 give guidance on management responsibility, resources, measurement and improvement with regard to obsolescence management. Cl
32、ause 7 gives guidance on planning, strategies and options described for hardware (including integral software). Clause 9 gives guidance on planning, strategies and options for software that is separable from its hardware. 5 EN 62402:2007OBSOLESCENCE MANAGEMENT APPLICATION GUIDE 1 Scope This Internat
33、ional Standard gives guidance for establishing a framework for obsolescence management and for planning a cost-effective obsolescence management process that is applicable through all phases of the product life cycle, the term product includes: capital equipment; infrastructure; consumer durables; c
34、onsumables; software products. Obsolescence management covers the following areas: a) design of new products; b) new technology insertion into existing products; c) support and maintenance of legacy products. 2 Normative references The following referenced documents are indispensable for the applica
