Abstract
D.Phil.
The thesis provides an overview on the problem of component obsolescence (electronic and other types of components) in the South African context. By assessing applicable literature as well as feedback and lessons learned from relevant projects, a model for the management of component obsolescence is proposed. The aim of the research is to provide a definition of component obsolescence drivers and to formulate a model for the management of component obsolescence. Guidelines on how these management activities can be optimised in the different life cycle phases of projects in order to reduce applicable obsolescence risks are provided. A costing model to calculate the applicable costs associated with component obsolescence in the South African context is also proposed. In order to implement successful obsolescence management, the following approach is proposed: Ensure that the drivers of component obsolescence supported by a costing model to calculate the applicable obsolescence costs, and the possible impact thereof, is made visible to applicable levels of management; Encourage projects to support a process that is directed at addressing obsolescence risks applicable to that project by introducing obsolescence management as an important part of the Through Life Support (TLS) planning of all long-term projects or complex equipment; Promote an environment where obsolescence management is an integral part of the system engineering process so as to optimise the rapid development processes (especially for electronic components) whilst also keeping support expenditure within acceptable limits; Adequate funding should be allocated to ensure that obsolescence risks and activities can be identified, addressed and monitored cost effectively over the complete life cycle of the product or system from initial design to end of support or phase-out of the system.
