Dialogue modelling of graphical user interfaces with a production system

Abstract

Abstract In systems development it is essential for a piece of software to be able effectively to incorporate the requirements of the particular task domain that it is intended to address. This paper describes an approach that uses dialogue modelling to carry the requirements derived from task analysis through to the implementation phase of development. A notation based on production systems is used to develop an abstract specification of user and system behaviour which can subsequently be used as the basis for the implementation. The requirements for a computer-based tool are also discussed, with particular attention being given to ways in which the communication and reasoning about such a dialogue design can be supported.
