Assessing mental and operational workload to ensure staff in safety-critical environments can perform their tasks safely, effectively, and sustainably.
Organisations operating safety-critical systems rely on personnel who must maintain high levels of attention and performance over extended periods. When workload becomes too high—or unevenly distributed—it can increase the risk of errors, reduce resilience, and negatively affect staff wellbeing. Many organisations therefore need better insight into how workload develops during real operations and how staffing, procedures, and technology influence it.

Our analyses provide organisations with concrete insights into how operational workload develops in practice. The results support decisions on staffing levels, task allocation, system design, and operational procedures. By aligning workload with human capabilities, organisations can improve safety, operational performance, and long-term workforce sustainability.
