The purpose of a Human Readiness Level (HRL) scale is to indicate a developing system’s readiness for use by humans, that is, the maturity of human engineering efforts. We explore the factors driving the development of the HRL scale, how the scale enhances systems engineering and program execution, and potential shortcomings. We focus on the American National Standards Institute and Human Factors and Ergonomics Society (ANSI/HFES) 400-2021 standard, which includes an HRL scale and implementation guidance. Utilizing HRLs improves the integration of human systems considerations in the engineering process and results in improved system performance and life cycle concept realization.

人类准备水平 (HRL) 量表的目的是表明开发系统是否准备好供人类使用，即人类工程工作的成熟度。我们探讨了推动 HRL 量表发展的因素，量表如何增强系统工程和程序执行，以及潜在的缺点。我们专注于美国国家标准协会和人为因素与人体工程学协会 (ANSI/HFES) 400-2021 标准，其中包括 HRL 量表和实施指南。利用 HRL 可以改进工程过程中人类系统考虑因素的集成，并导致系统性能和生命周期概念实现的改进。
