ISA–RP77.60.05–2001 (R2012), Fossil Fuel Power Plant – Human-Machine Interface Task Analysis, offers a detailed approach to conducting task analysis specifically for designing and upgrading control rooms in fossil fuel power plants. This recommended practice emphasizes how early and thorough examination of operator tasks can influence the development of human-machine interfaces (HMI), helping to identify necessary information and controls, organize displays effectively and evaluate design options through mockups and walkthroughs. By highlighting key and common operator activities, this approach enhances decision-making throughout all phases of system design, from initial concepts to detailed development, including testing and validation.This recommended practice features a practical case study demonstrating how task analysis improved display requirements and console layouts during a two-unit plant upgrade. This illustrates its effectiveness in creating more functional and user-friendly control environments.
