Abstract
The DOD embedded computer resources (ECR) environment today reflects a history of problems the military departments have encountered in their expanding use of computers in systems that must survive and interoperate in wartime environments. There has been uncontrolled proliferation of hardware and software, low interoperability and interchangeability, and maintenance and logistics difficulties. The result is uncomfortably high life-cycle costs and a lack of satisfaction with the final product. Estimates by independent sources indicate that DOD's investment in embedded computer hardware and software will increase from approximately $4.1 billion in 1980 to more than $30 billion in 1990. The nature and source of the high cost have also been changing. Technological advances in the computer field have, for example, shifted the systems life-cycle cost from hardware to software. Hardware life-cycle cost now represents only a small percentage of the total system cost. In the case of software, operational life-cycle cost exceeds by far development cost. It is estimated that software maintenance cost is approximately 70 percent of the life-cycle cost for most weapon systems.
