Design refreshes and various reactive mitigation solutions are used to manage technology obsolescence (DMSMS) in systems. Design refreshing solely to manage obsolescence is, however, not practical for many systems, and therefore, obsolescence management refresh activities need to be coordinated with technology insertion roadmaps. This report describes the development of an information model that details technology roadmapping information for use within obsolescence-driven design refresh planning, and also describes a business case analysis for ascertaining the value of the resulting refresh plans. A case study on the V-22 Advanced Mission Computer using the MOCA (Mitigation of Obsolescence Cost Analysis) refresh planning tool is described in which optimum refresh plans (coupled with bridge and lifetime buys) with and without the inclusion of technology roadmapping constraints are determined.
