Enterprise Resource Planning Program

The Defence Enterprise Resource Planning (ERP) Program is a Defence-wide priority and a key part of the Defence transformation agenda.

ERP is enabling Defence to better adapt and evolve to meet strategic challenges, and Defence Industry continue to play a key role in supporting the successful implementation of ERP capability.

The ERP Tranche 1B Main release on 12 May 2025 is Defence’s fifth and largest ERP capability release to date, bringing finance, procurement, supply chain management, transport management, land maintenance and engineering within ERP. This release significantly expands the number of users accessing ERP in the course of their day-to-day activities within Defence.

The following video demonstrates the commitment from Defence senior leaders in delivering ERP in Defence.
