human-reliability is the concept of quantifying the likelihood that a human operator will execute a required task correctly under specified conditions and within a defined time window. It parameterizes human performance as a probabilistic variable subject to degradation under stress, fatigue, ambiguity, or time pressure, and persists through human error databases, reliability prediction methods, and training protocols that model and improve operator performance.

Definition
Why it is in scope
A human-made concept in safety engineering and organizational psychology representing the probability that a human operator will perform a required task correctly under specified conditions within a given time. Built to persist through quantitative models, training protocols, and reliability databases that predict and improve human performance under stress.

for-whose-sake: human-reliability quantifies how likely operators are to perform correctly, and this quantification is maintained specifically to serve the human-factors discipline, which uses such data to design systems around human capabilities and limitations. The purpose is by design — safety engineers quantify reliability to inform human-factors optimization.

Human-reliability is maintained for the sake of safety-management: it measures and models human error rates to inform safety decisions, training, and system design. The servant (reliability metric) points at the master (management).
