ISA RP77.60.05 – Fossil Fuel Power Plant Human Machine Interface: Task Analysis

Approaches are provided in this recommended practice for the application of task analysis during theconceptual design, preliminary design, and detailed design phases, as well as the test and evaluation ofcontrol room upgrade/development programs. Although the relationship between task analysis and othersystem development techniques is briefly considered, the emphasis is clearly on the methods and benefitsto be derived from a detailed analysis of operator functions and activities in the control room.Methods used to support the task analysis are also presented. These include the use of surveys andquestionnaires, tabletop analysis approaches, and the use of mockups and walkthroughs.Applications of the data are considered for addressing a number of design-related issues. The discussionin this section will focus on the analysis of operator tasks, but could be extended to include maintainertasks.
