A Clearinghouse for Software Reuse: Lessons Learned from the RAPID/DSRS Initiatives by Gerard R. Harms Lieutenant Commander, United States Navy B.S., University of Villanova, 1978 and Tina H. Van Hook Lieutenant, United States Navy B.B.A., University of San Diego, 1985 Submitted in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN INFORMATION SYSTEMS from the NAVAL POSTGRADUATE SCHOOL September 1992 ABSTRACT Information systems executives withinDepartment ofDefense (DoD) activities are being challenged to develop innovative ways in which information technology can contribute to the streamlining of DoD organizations. Software reuse is a key strategy in DoD developing information systems that will meet the future needs of organizations. This thesis examines the concepts, and issues relating to the creation of a clearinghouse to facilitate and promote software reuse. Specifically it studies the Defense Software Repository System (DSRS), a DoD-wide version ofthe Army Reusable Ada Products for Information Systems Development (RAPID) effort. 111 2/1 t.i TABLE OF CONTENTS I.

This thesis is part of a larger study sponsored by the Director of Defense Information (DDI) in which a series of case studies are being conducted to focus on the sound practices ofMIS implementation in DoD. This particular case study examines the concept of software reuse and focuses on the DoD Defense Software Repository System (DSRS) initiative. DSRS is a DoD version of the Army's Reusable Ada Products for Information Systems Development, and their methodology for software reuse. It will also identify critical success factors in implementing a DoD-wide policy on code reuse. PURPOSE OF RESEARCH B. The DoD Corporate Information Management (CIM) initiative promotes the use of Information Technology to improve business processes and the management of information resources. Software reuse has been identified by the Office of Defense DoD Information as a key strategy intended to help respond to variable threats in a rapidly changing environment with less resources. The integration of software reuse practices into lifecycle development ofDoD systems will be a critical factor in achieving significant reduction in the amount of time required to develop complex systems. Equally important is the anticipated increase in system reliability and decrease in dollars spent for systems maintenance following implementation. The DSRS goal is to obtain general purpose, adaptable software components that have maximum potential for reuse. They have established procedures and guidelinesto certify reusable software components. RESEARCH METHODOLOGY C. This thesis is a case study that reviews recent literature on software reuse, conducts on site field interviews with CIM, RAPID, and DSRS personnel, and derives lessons learned from the RAPID/DSRS effort achieved to date. This study focuses on the RAPID/DSRS effort and the methodology for software reuse. RAPID/DSRS provides a comprehensive and structured framework for software reuse that could be of potential benefit to all users. Procedures to certify reusable software components proposed by RAPID will also be discussed. D. RESULTS OF RESEARCH The results of this research, and all references are contained in the Appendix.
