Abstract
The world of today is characterized by very rapidly changing conditions that require rapid responses. This implies a need for software that can be easily adapted to changes in its domain of application, and this in turn implies that we must understand how to use effectively models of the application domain. Unfortunately there is considerable confusion regarding domain analysis, which seems to be due to the comlex stucture of realistic domain models. In an attempt to remove some of the confusion, we describe application domains in terms of patterns, suggest a structure for a pattern library, and introduce a format in which patterns are to be defined. In this we distinguish between patterns that define the normal mode of operation of a system, patterns that relate to exceptional conditions, and patterns that deal with cooperation within a system and between more or less independent systems. Our examples of entries in the pattern library consist of capsule summeries for a generic "rental" process, and definitions in full of several such patterns for a car-rental and a restaurant business. The expanded patterns have a natural language version and a version expressed in our formalspecification language SF. In student group projects, groups of six students have converted the capsule summaries for rentals into a reasonably well verified implementations of software support systems for a rental-car company in approx. 60 hours, i.e., in 360 person hours. We have also developed patterns for an unrelated area, the monitoring of a safety-critical system. We introduce a software development process that is to allow rapid configuration of new systems from existing patterns. As a suggestion for future work we look at the role of intelligent software agents in such a process.
