This case study focused on obsolescence management constraints that occur during development of sustainment-dominated systems. Obsolescence management constraints were explored in systems expected to last 20 years or more and that tend to use commercial off-the-shelf products. The field of obsolescence has received little study, but obsolescence has a large cost for military systems. Because developing complex systems takes an average of 3 to 8 years, and commercial off-the-shelf components are typically obsolete within 3 to 5 years, military systems are often deployed with obsolescence issues that are transferred to the sustainment community to determine solutions. The main problem addressed in the study was to identify the constraints that have caused 70% of military systems under development to be obsolete when they are delivered. The purpose of the study was to use a qualitative case study to identify constraints that interfered with obsolescence management occurring during the development stages of a program. The participants of this case study were managers, subordinates, and end-users who were logistics and obsolescence experts. Researchers largely agree that proactive obsolescence management is a lower cost solution for sustainment-dominated systems. Program managers must understand the constraints and understand the impact of not implementing proactive solutions early in the development program lifecycle. The conclusion of the study found several constraints that prevented the development program from early adoption of obsolescence management theories, specifically pro-active theories. There were three major themes identified: (a) management commitment, (b) lack of details in the statement of work, and (c) vendor management. Each major theme includes several subthemes. The recommendation is future researchers should explore two areas: (a) comparing the cost of managing obsolescence early in the development process versus the costs of managing later, (b) exploring the costs and value to start a centralized obsolescence group at each major defense contractor location.
