The management of obsolescence problems is often referred to as “diminishing manufacturing sources and material shortages” (DMSMS) (Saunders, 2006). As addressed in this book, DMSMS specifically refers to the loss of the ability to procure required materials, parts, or technology.

The process for managing obsolescence is illustrated in Figure 1-3 to mitigate or avoid the impact of supply shortfalls for all types of materials, parts, devices, software, services, and processes during the intended life of a product.
