This presentation describes the Human Readiness Level (HRL) scale and its application in the systems engineering process. The HRL scale is a simple nine-level scale designed to complement and supplement the Technology Readiness Level (TRL) scale in order to evaluate, track, and communicate the readiness of a system for safe and effective human use. Application of the HRL scale ensures proper attention to human systems design throughout design and development to minimize or prevent human error. The HRL scale was codified into a formal technical standard and approved by the American National Standards Institute (ANSI) and the Human Factors and Ergonomics Society (HFES) in September 2021. The Joint Human Systems Integration (HSI) Steering Committee under the Office of the Under Secretary of Defense (OUSD) is currently working on a proposed path forward for Department of Defense (DOD) adoption of the standard. The standard is also being applied to ongoing Army and Federal Aviation Administration (FAA) work. A complimentary copy of the HFES 400-2021 standard can be downloaded at
