Many systems face a similar obsolescence issue, which is that the desired system deployment life cycle is much longer than the life cycle of the constituent parts (hardware and software) that make up the physical architecture. Thus, the system baseline must evolve over its operational life cycle just to remain functionally viable. This problem is compounded as the size of the system grows toward network‐centric system‐of‐systems and as the use of commercial technologies and products increases. Thus, the challenge is to perform technology assessments that facilitate the forward planning of technology evolution on the system of interest. A corollary challenge is to perform this planning while simultaneously optimizing the life cycle affordability for the customer. This paper provides a methodology for taking current technology information and transforming it into a system evolution plan (the term system being used in the most general sense to encompass sub‐assemblies through system‐of‐systems) using affordability as the optimizing variable for technology change incorporation.
