Presentation at Hazards30 2020 on Human Factors Safety Critical Task Analysis.

Safety Critical Task Analysis (SCTA) vary in their quality of application and output. Smith and Koop (2011) list conditions that affect SCTA performance, but there has been relatively little other work to build on this. As a company we have been practising SCTA for over 30 years, evolving and improving our practices along the way. To identify some of the features of what makes a SCTA a success, and where it could be improved, we reflect on these experiences and report our analyses. To help shape our findings and communicate the results we use Team GB cycling team’s approach 'aggregation of marginal gains' as a lens to study SCTAs. Essentially, this focuses on how small improvements can lead to significant performance gains. We also highlight the issue of the Goldilocks problem, which seeks to balance gains in efficiency and thoroughness so SCTA is neither too fast and shallow nor too slow and effortful with a potentially redundant level of depth.
