This document provides the specification of the Process Interchange Format (PIF) version 1.2. The goal of this work is to develop an interchange format to help automatically exchange process descriptions among a wide variety of business process modelling and support systems such as workflow software, flow charting tools, planners, process simulation systems and process repositories. Instead of having to write ad hoc translators for each pair of such systems each system will only need to have a single translator for converting process descriptions in that system into and out of the common PIF format. Then any system will be able to automatically exchange basic process descriptions with any other system. This document describes the PIF-CORE 1.2, i.e. the core set of object types (such as activities, agents and prerequisite relations) that can be used to describe the basic elements of any process. The document also describes a framework for extending the core set of object types to include additional information needed in specific applications. These extended descriptions are exchanged in such a way that the common elements are interpretable by any PIF translator, and the additional elements are interpretable by any translator that knows about the extensions. The PIF format was developed by a working group including representatives from several universities and companies, and has been used for experimental automatic translations among systems developed independently at three of these sites. This document is being distributed in the hopes that other groups will comment upon the interchange format proposed here, and that this format (or future versions of it) may be useful to other groups as well. The PIF Document 1.0 was released in December 1994, and the current document reports the revised PIF that incorporate the feedback received since then.

Design Rationale Management Research

  • Jintae Lee

Many benefits potentially stem from a structured representation and use of “design rationales”, i.e. the deliberations underlying a software design process. Explicitly-represented rationales help us understand the design better so that we can produce a better design, maintain the resulting artifact better, and exploit the cumulated knowledge when we need to redesign it. Explicit representation of the rationales also provide a basis for reviewing or justifying the decisions that have been made, for communicating with other members of the design team more easily, and for defining computer services that support various design activities, such as keeping track of dependencies or managing multiple viewpoints. Technologies, that have recently become available, such as multi-media and distributed databases, provide the necessary ingredients for pursuing these potential benefits seriously. As a result, in the past few year we have seen growing interest in design rationale management.
