This standard defines the nine levels of the Human Readiness Level (HRL) scale and provides guidance for their application in the context of systems engineering and human systems integration processes. In September 2021, the American National Standards Institute (ANSI) formally approved a newly developed standard: ANSI/HFES 400-2021, Human Readiness Level Scale in the System Development Process. Additionally, HFES standards are downloadable from ANSI.ġ08 pages, 38 figures, 5 tables, 8.5 x 11', PDF on CD-ROM & paperbackĪNSI/HFES 400-2021, Human Readiness Level Scale in the System Development Process Order a copy in print or PDF from Techstreet. It provides specific guidance for the design and installation of computer workstations, including displays, input devices, and furniture that will accommodate a wide variety of users. This document replaces BSR/HFES 100-2002 and ANSI/HFS 100-1988. In November 2007, the American National Standards Institute approved ANSI/HFES 100-2007, Human Factors Engineering of Computer Workstations as an American National Standard.

The updated (current) version was released in 2007, and work is well under way for a new update.

In the 1990s, the Society refined and consolidated its standards activities and embarked on a revision of ANSI/HFS 100-1988. This groundbreaking standard established voluntary specifications for the ergonomic design of computer workstations for the seated operator. In 1988, HFES published ANSI/HFS 100-1988, American National Standard for Human Factors Engineering of Visual Display Terminal Workstations. Since the early 1980s, HFES has participated in the development of American national standards and has worked to establish U.S.
