The authors have conducted a field study of large-system-development projects to gather empirical information about the communication and technical decision-making processes that underlie the design of such systems. The findings of this study are reviewed for their implications on modeling the process of designing large software systems. The thesis of the paper is that while there are many foci for process models, the most valuable are those which capture the processes that control the most variance in software productivity and quality.

The author describes the development of a prototype visual environment for developing, recording, and communicating computer system designs. He begins by defining the terms designer and design, and describes the set of activities which designers perform. He conjectures that a visual designer's environment could be designed to support these activities, providing significant leverage in productivity. He describes the process followed in designing and implementing VERDI, a visual design environment prototype that focuses on distributed system design. The author presents some of his conclusions and some further conjectures that his continuing research incorporates.

A description is given of PARIS, an implemented system that facilitates the reuse of partially interpreted schemas. A schema is a program and specification with abstract, or uninterpreted, entities. Different interpretations of those entities will produce different programs. The PARIS system maintains a library of such schemas and provides an interactive mechanism to turn a schema into a useful program by means of partially automated matching and verification procedures.

Most software process models are based on the management tracking and control of a project. The popular alternatives to these models such as rapid prototyping and program transformation are built around specific technologies, many of which are still in their adolescence. Neither of these approaches describe the actual processes that occur during the development of a software system. That is, these models focus on the series of artifacts that exist at the end of phases of the process, rather than on the actual processes that are conducted to create the artifacts. We conducted a field study of large system development projects to gather empirical information about the communication and technical decision-making processes that underlie the design of such systems. The findings of this study are reviewed for their implications on modeling the process of designing large software systems. The thesis of the paper is that while there are many foci for process models, the most valuable are those which capture the processes that control the most variance in software productivity and quality.

This paper introduces an application-specific hypertext system designed to facilitate the capture of early design deliberations, which implements a specific design method called Issue Based Information Systems (IBIS). The hypertext system described here, gIBIS(for graphical IBIS), makes use of color and a high speed relational database server to facilitate building and browsing typed IBIS networks. Further, gIBIS is designed to support the collaborative construction of these networks by any number of cooperating team members spread across a local area network. Early experiments suggest that the gIBIS tool, while still incomplete, forges a good match between graphical interface and design method even in this experimental version.

This is an overview of the combat system test and certification (CST&C) program as a subset of the total ship test program (TSTP) for active fleet surface ships. The paper will discuss how the T&C program measures not only the suitability of repairs and modifications done during a ship's combat system industrial availability in a public or private yard period, but also the impact that successful program conduct has on the materiel effectiveness throughout a ship's operational cycle. The CST&C management organization and responsibilities, including NAVSEA's master ordnance repair program as well as combat system code 190's relationship to the CST&C program and the impact of pre- and post-industrial testing requirements on the actual conduct of industrial testing will be addressed.

Today's design tools are geared toward the development and retention of design artifacts: documents that describe a design, or plan, that if implemented will provide the desired software system. The other product of the design process - the understanding, or problem formulation - is often lost. We present a model of design in which the development of understanding and the creation of artifacts are explicit components.
