“…Consider just the task of designing software -many tools (e.g., CASE tools) are available to aid in managing the myriad of details inherent in the realization of a design, but none explicitly support the conceptual aspects of this tasks. Recent research applying hypertext technology to the software process is promising, but these systems are experimental; they are also points within a very large design space [see, for example , Scacchi, 1988;Nagl, 1986;Delisle & Schwartz, 1986;Taylor, et. al, 1987;Bigelow & Riley, 1987;Biggerstaff, et.…”

This report describes a new project in computer-supported collaboration for scientific and engineering professionals, made possible by support from NSF, IBM, and ONR. For over twenty years the Department of Computer Science at the University of North Carolina-Chapel Hill has successfully conducted research on systems for intelligence amplification. Our longest continuing project of this kind has been the application of interactive computer graphics to assist a biochemist elucidating the structure of a complex protein molecule. A more recent project has developed a hypertext-based system designed to support authors of scientific, technical, and other expository documents.

“…The sequence of their invocation is mostly nondeterministic and nonprocedural, but easily tracked by individual software engineers for small programs. However, if the programs being developed are large, built by teams developing multiversion program components according to an elaborate life-cycle engineering methodology (Scacchi, 1988;Garg & Scacchi, 1989a), then the program writing task becomes complex and costly if not well-coordinated.…”

“…Next, I examine five application domains for hypertext environments in order to identify the supporting tools and document production/consumption techniques associated with the processing of information content within each domain. The focus then shifts to describe the structure of information to evolve within a DSHE in terms of product, task, and setting information for the domain of computer-aided software engineering (CASE) as used in the System Factory Project at USC [36]. Together, these sections then set the final stage for a discussion of the power of DSHE.…”

What Is the potential power of hypertext technology?This article examines this question and outlines the answer by focussing attention to a domain-specific view of hypertext environments. The author first defines what domain-specific hypertext environments (DSHE) represent. Next, the author examines DSHE for the domains of journal and book publishing, insurance policy management, and software engineering. Then the author describes in more detail the structure of informatlon to evolve within a DSHE for software engineering in terms of document products, processing tasks and mechanisms, and workplace attributes. In turn, this examination provides the basls for identifying seven dimensions along which the power of DSHE can be defined, experienced, and accumulated. The author also addresses the organizational costs that may be borne to realize thls power. The author concludes with observations as to the source of DSHE power as well as identifying topics for futher investigation. IntroductionWhat is the power of hypertext?* Power in other contexts usually refers to the ability of some entity or agent to affect the behavior of another, or to achieve advantage over another in ways that the other cannot avoid. Following this, it might be expected that as a technology, hypertext systems offer relative advantage over alternatives to automated text/document information systems including conventional word processing systems, file systems, and data base management systems. In this way, hypertext systems offer a degree of information processing power that enables new kinds of applications, much like the advent of so-called expert system shells+ enabled the creation of expert applications for domains such as computer configuration and pathological diagnosis. Similarly, as a medium for *The term "hypertext" is used to be synonymous with "hypermedia" and other similar terms that denote the nonlinear representation of interrelated textual, graphic, filmic, or auditory information.'In other places, such shells are considered "domain-independent", but when instantiated with rules about patterns among application domain data, the expert system application is considered "domain-specific." 01989 by John Wiley & Sons, Inc.writing and reading electronic documents hypertext systems allow the redefinition of the structure and content of documents which alter the constraints and opportunities for conveying information in contrast to the linear print medium. Thus, the power of hypertext in whatever form it exists is subtle and incremental: it is potential rather than kinetic. However, such power can accumulate in different application domains in the long run if effectively mobilized and integrated with domain-specific tasks, processing mechanisms, and workflow.The power of hypertext technology in different application domains can be realized in a number of ways. In particular, technology that supports a unified view of the hypertext documents, production processes, processing mechanisms, and settings of use appears to offer the greatest powe...

Metaparadigm: A soft systemic MIS design approach

The aim of this paper is to introduce the soft systemic approach to medical information system design, called metaparadigm. The metaparadigm is a metadesign paradigm. Using it we first design an IS design paradigm and it is our deep belief that metaparadigms employment can enhance many conventional IS design weaknesses and result in successful information system design and use. In the paper we show the applicability of the metaparadigm in MIS design and introduce a new personal MIS design paradigm.
