Core Banking Modernisation for a Major Australian Bank

A major Australian bank was operating a long-serving core banking platform across many business units. Overnight batch processing constrained the settlement window, and the accumulated complexity of the existing estate had made earlier modernisation efforts difficult to land. The board wanted a renewal that would modernise the platform while protecting continuity of service and regulatory standing throughout.

Precision provided executive programme leadership, taking accountability for the modernisation from planning through to cutover. The first weeks established a clear view of the technical estate, the regulatory obligations, and the dependencies that had made prior efforts hard to complete. Delivery was restructured into staged tranches with tested fallback positions at every critical milestone, so that no step carried an all-or-nothing risk. The vendor relationship was placed on an outcome-based footing, and a parallel-run testing approach gave the board evidence of readiness before each go-live decision.
