Use of Structured Development Techniques to Specify the User-System Interface

Abstract

The Human Factors Engineering products from the systems requirements phase of system development were transformed into techniques consistent with structured software development techniques. These techniques supported definition of the mission functions with the context diagram, the task list was compatible with the event list, and high level functional flow diagrams are consistent with the structured data flow diagrams. In addition, the sequenced task analysis procedures used provided a structured diagraming methodology in state transition diagrams. This technique provided a method for defining MMI requirements in software engineering terminology.
