Companies are increasingly looking at their operations to assess their resilience and identify their vulnerabilities. Rather than seeing SPADs in isolation, with unrelated causes, companies are looking across their incidents, network and people to understand the precursors to SPAD risk. This article provides some examples of work done, and guidance to help your work in this field.
Sometimes operational reviews are triggered by a peak in SPAD events. For example, Period 3 in the spring of 2018 saw a significant increase in the number of SPADs compared to previous years. A review of 35 of these SPAD investigations was carried out using the 10-incident factor framework. This identified that several changes across the industry coincided and contributed to this peak. These included: re-signalling schemes, issues with vegetation management and timetable changes.
