ISA RP77.60.05-2001 (R2007)

Approaches are provided in this recommended practice for the application of task analysis during the
conceptual design, preliminary design, and detailed design phases, as well as the test and evaluation of
control room upgrade/development programs. Although the relationship between task analysis and other
system development techniques is briefly considered, the emphasis is clearly on the methods and benefits
to 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 and
questionnaires, 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 discussion
in this section will focus on the analysis of operator tasks, but could be extended to include maintainer
tasks.
