When developing ecological displays for a large project, having consistent techniques for analysis and design are very important. This paper reports on six techniques that were used on a project for Syncrude Canada. The project used work domain analysis to develop ecological display concepts. At various points in the project, a total of eight analyst designers were involved. The six techniques reported here were used to maintain consistent results across the design team and to provide a systematic approach to move from a work domain analysis to a design on a large safety-critical project.
