Course Overview
This course reviews DMSMS management best practices, the various mitigation approaches, and available methods of forecasting the obsolescence of parts. In addition, pro-active methods for managing obsolescence are discussed, including design refresh planning and the use of ASICs. The course is divided into 6 sections that cover:
- Introduction to Electronic Part Obsolescence
- Electronic Part Obsolescence Forecasting
- Electronic Part Obsolescence Mitigation
- Obsolescence Management Plan and Case Resolution
- Strategic Obsolescence Management
- Electronic Part Total Ownership Cost Modeling
- Software Obsolescence
The course includes a review of commercial databases and associated decision support tool offerings.
