An obsolescence management framework for a defense industry company

Saygın, Nilüfer
This thesis presents an analysis of the processes related to the obsolescence management of electronic components in a large scale defense industry company. These proceses are: Project Management, Research and Development, Manufacturing and Services, and Supply Chain Management. The current obsolescence problems, and the company’s reactive approach to resolving these are described. A new obsolescence management framework is proposed in order to mitigate and resolve obsolescence problems in electronic components. The framework targets the reduction of the negative impacts of obsolescence throughout the lifecycle of products, as well as the elimination of the communication and integration deficiencies in existing processes. It recommends the extension of the scope of Product Lifecycle Management in the company, the establishment of a companywide Preferred Parts List and standardization of existing electronic component libraries, the introduction of Complex Event Processing to manage obsolescence, and the incorporation of a new obsolescence management process within a “shell structure” that integrates all obsolescence related processes.
