Approaches are provided in this recommended practice for theapplication of task analysis during the conceptual design,preliminary design, and detailed design phases, as well as the testand evaluation of new control rooms/systems and control roomupgrade/development programs. Although the relationship betweentask analysis and other system development techniques is brieflyconsidered, the emphasis is clearly on the methods and benefits tobe derived from a detailed analysis of operator functions andactivities in the control room.
Methods used to support the task analysis are also presented.These include the use of surveys and questionnaires, tabletopanalysis approaches, and the use of mockups and walkthroughs.
Applications of the data are considered for addressing a numberof design-related issues. The discussion in this section will focuson the analysis of operator tasks, but could be extended to includemaintainer tasks.
Purpose
The purpose of this document is to provide guidance and suggestan approach for conducting a task analysis as part of the designand development of new control rooms/systems for power plants andfor supporting major control room upgrade programs. The basicpremise is that task analysis data, when collected early, isbeneficial throughout the design process and serves to identifyinstrumentation needs, assist in evaluating design options, and invalidating completed designs for human-machine interfaceconcerns.
This particular document is one of three parts. The reader isencouraged to consult the remaining two documents for additionalinformation in performing integrated control room design. Thesedocuments are:
ISA-RP77.60.02-2000, Fossil Fuel Power Plant Human-MachineInterface – Alarms
ISA-TR77.60.04-1996 (R2004), Fossil Fuel Power PlantHuman-Machine Interface – Electronic Screen Displays
