Real Time Systems/Software Methodologies for Large Aerospace Systems

Abstract

This paper presents an overview of the real time system/software methodology approach being deployed within Hughes Aircraft Company. The Hatley‐Pirbhai Process for System Development (PSD) was chosen as the training standard for all systems and software engineers in a common engineering method to increase productivity, quality of design, and communications between various engineering disciplines. The approach that Hughes has taken is to adopt a well defined and proven methodology available from industry and to customize it to include specific extensions applicable to the types of systems developed by Hughes Aircraft product organizations. Two such extensions, information modeling and requirements traceability tooling, are discussed in this paper. In conclusion, the paper will discuss the lessons learned for using the integrated system development methodology and follow‐on activities that are being worked on today.
