When accurate data on operational workloads is brought together with reliable workforce plans, future resource-related performance can be simulated and modelled. In times of major development and change, such as large scale recruitment drives or bringing new facilities on-stream, our models provide powerful flexibility to test and visualise different planning scenarios. Our data-driven models also provide early foresight of resilience risk or potential additional capacity. The results can also be used to evaluate past resilience issues and causes. In times of heightened scrutiny or operational crises, our models can also be used to stress test contingencies and re-formulate resource plans.
