The Nick Summer Experiment was an empirical study undertaken to explore and increase the understanding of the use of prototype meeting support technology by software design teams working on high-level design problems. Three teams of seven designers each were observed and videotaped while participating in 27 1-h, face-to-face design meetings in both the electronic meeting room and in a conventional meeting room. The Nick support technologies explicitly aided the affective social meeting structures as well as the rational task-oriented processes. The analysis of the experimental data revealed some gains in meeting effectiveness and quality from use of the Nick meeting support technologies. The subchannel (messaging facility on the electronic workstations) emerged as a potentially effective way for participants to attain more equality and to influence the direction of the meetings. The electronic blackboard helped to increase group focus and attention on completing the task.< >

Reinterprets data from an empirical study conducted in 1987 –the Nick Experiment – concerned with the interaction betweentechnology, team and task. Combines data with anecdotal *** gains in meetings quality and effectiveness. Comments on thepotential effectiveness of the messaging facility on the electronicworkstations and the electronic blackboard. Comments strongly on thevalue of field experiments and case studies – as opposed tocontrolled experiments – to obtain realistic data.

The authors outline a generic model for representing design deliberation and the relation between deliberation and the generation of method-specific artifacts. A design history is regarded as a network consisting of artifacts and deliberation nodes. Artifacts represent specifications or design documents. Deliberation nodes represent issues, alternatives or justifications. Existing artifacts give rise to issues about the evolving design, an alternative is one of several positions that respond to the issue (perhaps calling for the creation or modification of an artifact), and a justification is a statement giving the reasons for and against the related alternative. The model is applied to the development of a text formatter. The example development is represented in hypertext and as a Prolog database, the two representations being shown to complement each other. The authors conclude with a discussion of the relation between this model and other work and of the implications for tool support and methods.

We outline a generic model for representing design deliberation and the relation between deliberation and the generation of method-specific artifacts. A design history is regarded as a network consisting of artifacts and deliberation nodes. Artifacts represent specifications or design documents. Deliberation nodes represent issues, alternatives or justifications. Existing artifacts give rise to issues about the evolving design, an alternative is one of several positions that respond to the issue (perhaps calling for the creation or modification of an artifact), and a justification is a statement giving the reasons for and against the related alternative. The model is applied to the development of a text formatter. The example necessitates some tailoring of the generic model to the method adopted in the development, Liskov and Guttag's design method. We discuss the experiment and the method-specific extensions. The example development has been represented in hypertext and as a Prolog database, the two representations being shown to complement each other. We conclude with a discussion of the relation between this model and other work, and the implications for tool support and methods.

A description is given of a suite of tools to support analysis of properties of sequences associated with a specification, with input or output to a program, or with simple behavioral models of a system under design. The toolset's capabilities include: generating sequences to satisfy combinations of conditions, organizing these condition combinations as tables of cases to serve as test data and visualizing the effects of executing a chosen sequence. The technology base is Prolog extended with a powerful window package.< >

A large part of the value of the US Space Station will reside in the information exchanged between it and the related ground facilities. To insure that this exchange is effective, the Space Station Information Systems (SSIS) has been identified as an explicit element of the program and a management structure has been put in place to oversee the development of the end-to-end system, including those elements not provided by NASA. The SSIS is an extensive collection of hardware (computers, networks, facilities) and software, whose primary purpose is to carry data between a space-based source and a ground-based user.< >

The authors examine one particular aspect of the group process of software design, namely the interpersonal conflict that occurs within a software design team. Structured observations of the conflict that occurred within a set of team meetings that took place during the requirements-definition phase of an actual software development project form the basis for the analysis. It is shown that conflict is a consistent but fairly small percentage of the group interactions. Issues are not resolved in a top-down manner, and general issues such as project goals and overall design approach tend to resurface at later meetings. The implication of these findings for the design of computer-supported cooperative work environments for software design teams is explored.< >
