Abstract

DSTOP, the Design Support Tool for Operating Procedures, is a relatively simple software tool for support of designers of new interfaces and their procedures for use. DSTOP is based on two complementary models: the documentation coherence maxims and the situated-act model, which distinguishes domain actions from interface actions. Use of the tool involves the writing of operating procedures using a kind of grid, where the operating procedure runs from top to bottom and is divided horizontally into why, what and how elements. The why element represents the operating procedure's goal; the what represents the operating procedure's situated act; and the how represents the interface action(s) required to effectuate the act. The tool has been used to develop prototype operating procedures for computer-based aircraft cockpit interfaces. DSTOP adds new functionality associated with the coherence maxims, including explicit representation of variants of terms, and explicit tracking and display of procedures (and their why-what-how components) in which any of the variants is used.
