4 Obsolescence management initial planning An increased incidence in obsolescence is likely to be a significant factor in cost, supportability and product life cycle. It is essential therefore that customers and suppliers are pro-active in managing obsolescence from the outset. For a new project the project manager should analyse the anticipated project implementation(s), technology(ies) and support strategy(ies) taking into account their potential obsolescence. Where a product or programme already exists the project manager should analyse the product and support arrangements that have already been decided upon. Based on this analysis the project manager should consider the following risks over the life of the product.
a) What would be the impact of product being unavailable due to lack of spares
b) What would be the impact of performance degradation due to substituted parts
c) What would be the likely cost of premature replacement
d) What would be the likely cost of other measures to circumvent obsolescence
e) What is the probability of obsolescence occurring due to advances in technology
f) What is the probability of obsolescence occurring due to the introduction of new legislation? Having carried out an analysis there are two options available. These are based on the perceived risk of impact, cost and probability. The two main strategy options that should be considered are:
a) Strategy 1 — Reactive (see clause 6): React to problems of obsolescence as and when they occur;
b) Strategy 2 — Proactive (see clause 7): Develop and implement an obsolescence management programme.
5 The obsolescence management plan
5.1 General The project manager should produce an outline obsolescence management plan at the earliest stages of a project. However, everyone involved in the project should recognize that the finally agreed strategy will be influenced by proposals offered by contractors during the bidding phase. A costed obsolescence management plan for a specified project life should be a feature of an invitation to tender (ITT). The plan should be subject to planned review and maintenance. NOTE Obsolescence management does not operate in a vacuum. It is best integrated with other existing management plans.
5.2 Obsolescence management plan objective The objective of the obsolescence management plan should be to describe strategies for identification and mitigation of the effects of obsolescence through all stages of the product life cycle. The aims of the plan should be to:
a) achieve the optimum compromise between whole-life costs for the system, equipment performance and equipment availability and maintainability;
b) include all materiel regardless of whether it has been developed specifically for a customer;
c) be compatible with the customer’s current support arrangements;
d) provide a clear basis upon which obsolescence management requirements can be negotiated with suppliers and partners in collaborative projects;
e) be robust within an environment of change;
f) show consideration of the need for component or equipment requalification following component or module substitution.
5.3 Obsolescence management plan contents Details of plans, decisions and analyses should be recorded for later reference. The obsolescence management plan should initially record the choice of strategy. The level of detail in the plan should increase as the project proceeds. Subsidiary documentation should contain a full record of the factors in the analysis and trade-off arguments. The process for recording decisions is shown in Figure 1. As well as the record of decisions the obsolescence management plan should also identify the following aspects:
a) the periodicity of review;
b) the obsolescence management roles and responsibilities of the customer and supplier;
c) the current authority responsible for review and maintenance of the plan and the milestones for future transfer of ownership of the plan if applicable. Guidance on the content of an obsolescence management plan for the management strategies described for hardware (including integral software) can be found in clause 6 for Strategy 1 and in clause 7 for Strategy 2. Guidance on the content of an obsolescence management plan for the management strategies described for software that is separable from its hardware can be found in clause 8. 5.4 Budgetary provision Budgetary provision should take account of all aspects of the chosen strategy and contain sufficient funding for its implementation.BS 07000-5 pdf download.
