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.
On 12 May 2025, Defence delivered its fifth and largest ERP Capability release to date, the Tranche 1B Main (T1B Main) release, which brought finance, procurement, supply chain management, transport management, land maintenance and engineering within ERP. This release significantly expanded the number of users accessing ERP in the course of their day-to-day activities within Defence.
Defence will continue to advance capability through Tranche 3 (T3), focussed on strengthening, simplifying and modernising ERP capability across the enterprise to better support Defence’s current and future needs.
Benefits
ERP has introduced the latest SAP solution (SAP S/4HANA), and new and enhanced capability will continue to be delivered over a number of years, in a series of phases called 'tranches'.
The Defence ERP solution seeks to:
- drive alignment and standardisation
- implement fit for purpose IT systems
- encourage better ways of working
- develop and integrated force structure view with measurable inputs to capability.
Change effects
Defence values the ongoing partnership with industry and is committed to ensuring industry is informed, engaged and supported throughout this transformation as Defence continues to expand ERP capability.
Tranche 3 releases will have varying impacts on Defence personnel and Defence industry.
When changes affecting Defence industry are identified, Defence will work collaboratively with industry partners and suppliers to communicate the updates through their designated Defence Key Contact or Contract Manager.
For industry partners in ERP facing roles, training will be provided to those with minimum baseline clearance and Defence login credentials. Note that Defence does not intend to provide ERP training to industry partners who are not directly engaged in ERP facing roles within Defence. For prospective suppliers, pre-SAP training is not a pre-requisite or discriminator for future engagements with Defence.
Features
Timeline
Each tranche includes a discover, prepare, explore, realise, deploy and run phase, and are scheduled to deploy in a staggered approach.
Defence will continue to release ERP capability in staggered releases until 2030.
