HMI Usability and Performance
|Publication Date:||24 June 2019|
This ISA technical report (TR) addresses the specification, design, implementation details, and management (recommended practices) of an HMI (Human-Machine Interface) focused on usability and performance. It explains how the ANSI/ISA-101.01-2015
The ISA-101 standard covers the HMI lifecycle, including all general concepts until its decommissioning, applying a practical and management approach.
The purpose of having an automated process is to enhance process operations based on safety, performance, process improvements, availability, repeatability, and other relevant factors. HMIs are the main interface for users to interact with the process itself and they have the opportunity to facilitate operation or confuse users. This TR was written to provide guidance for the use of the ISA-101 standard as it applies to usability and performance, with due consideration to other guidance documents that have been developed throughout industry. Refer to clause 2 for references to these documents.
HMI enhancements for improved usability and performance are often associated with additional specifications, custom design, implementation, and management considerations, in addition to vendor-provided functionality and features. This technical report is intended to include examples of these considerations within the HMI lifecycle, including the continuous work processes of audit, validation, and management of change (MOC).
