Sustainment-dominated products particularly suffer the consequences of electronic part obsolescence because they have no control over their part supply chain due to their relatively low production volumes. DMSMS-type obsolescence occurs when long field life systems must depend on a supply chain that is organized to support high-volume products. Obsolescence becomes a problem when it is forced upon an organization; in response, that organization may have to involuntarily make a change to the product that it manufactures, supports or uses.6

The long-term management of DMSMS in systems requires addressing the problem on three different management levels: reactive, pro-active and strategic.
