International Telemetering Conference Proceedings / October 17-20, 1988 / Riviera Hotel, Las Vegas, Nevada / Software development is becoming less an art form and more an engineering discipline. Methods of software development which leave as little as possible to chance are constantly being sought and documented. However, the gap between what is written and what is actually applied is usually quite wide. The only way this gap can be narrowed is through practical application of these very detailed and complex methods. Since it is unlikely that the complexity of these methods will be reduced, automation must be employed wherever possible in the software development process. This paper addresses the successful development of software for the Navy's Realtime Telemetry Processing System III (RTPS III) using practical application of existing methodology in conjunction with a Computer Aided Software Engineering (CASE) tool. Based on this experience, the conclusion presents implications affecting software development the 1990s.

The research reported in this thesis is an extension and application of the results first introduced by the Procedural Approach to the Evaluation of Software Development Methodologies. The evaluation procedure offers a unique perspective based on the philosophy that a software development methodology should espouse a set of objectives that are achieved by employing certain U principles throughout the software development process, such that the products generated possess certain attributes deemed desirable. Further, definite linkages exist between objectives and principles, and principles and attributes. The work described herein adopts the perspective offered by the evaluation procedure and applies a critical analysis to the process-product relationships in DoD-STD-2l67 and DoD-STD-2l68. In support of the analysis, Augmented Data Flow Diagrams are introduced as an effective tool for concisely capturing the information in both standards. The results of the analysis offer a deeper insight into the requirements for defense system software development, such that one is able to better understand the development process, and more intelligently assess the quality of the software and documentation produced. / Master of Science
