ISA-TR101.01:2022

HMI Philosophy, provides comprehensive guidance for developing and implementing a human machine interface (HMI) philosophy in process automation systems, supporting the ANSI/ISA-101.01-2015, Human Machine Interfaces for Process Automation Systems standard. It outlines HMI systems' purpose, scope and lifecycle, emphasizing the importance of aligning with human factors engineering (HFE) principles to enhance operator effectiveness, safety and efficiency.This technical report details key components, such as system standards (including the HMI philosophy, style guide and object toolkits), design principles, implementation practices, operation, maintenance, continuous improvement processes like management of change (MOC), audits, performance monitoring and validation. It also addresses roles and responsibilities, security considerations, control room design and training requirements.ISA-TR101-01 serves as a foundational reference to help organizations create consistent, user-centered HMIs that support safe and efficient process control while allowing adaptability across different platforms and technologies.
