A paradigm for representing process information is described. It consists of a simple generic model and a specialization mechanism for customizing the model for any design method. The generic model supports the representation of design arti- facts, steps and heuristics. A specialization of the generic model for JSD is illustrated in detail. The JSD model is then applied to model episodes from a pedagogical design process: the design of a lift system controller.

Design decisions and assumptions that occur within and during the process of system design are not generally documented. The deliberation and much of the domain learning that went into resolving key design issues is thus wasted, increasing overall system costs. This cost is most apparent during maintenance, when a significant portion of engineer's time is spent trying to recover the lost rationale of the system structure. An approach is proposed for capturing this process-oriented material during development, indexed so that it provides this critical information to maintainers.< >

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 designers (seven mcc researchers per team) were observed and videotaped while participating in 27 one-hour, 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. 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. [ABSTRACT FROM AUTHOR]

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.
This paper describes an application specific hypertext system designed to facilitate the capture of early design deliberations. It implements a specific method, called Issue Based Information Systems (IBIS), which has...
