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 will enable Defence to better adapt and evolve to meet strategic challenges, and Defence Industry play a key role in ensuring the transition to ERP is successful. The following video demonstrates the commitment from Defence senior leaders in delivering ERP in Defence.


ERP is introducing the latest SAP solution (SAP S/4HANA) which will 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 an integrated force structure view with measurable inputs to capability.

Change affects

Business operation changes will have varying affects on Defence personnel and Defence Industry.

Defence is committed to ensuring industry is informed and involved in the transformation in order to enhance enterprise capability.

The key changes for Defence Industry will take place in 2024 as part of Tranche 1B Main and Tranche 2 Case Management, including:

  • delivery of an integrated supply chain capability
  • new enterprise asset management framework for Defence materiel
  • new master data standards and governance
  • new case management system
  • new system and ways of working
  • introduction of the SAP Business Network for Procurement
  • alignment of contracts and key performance indicators with ERP data
  • participation in ERP training.



Training will be provided to Defence contractors with minimum baseline clearance and Defence login credentials, guided by any contractual obligations. This will help prepare industry partners for the new ERP solution and ways of working.

Training programs for Tranche 2 Case Management will commence March 2024 and Tranche 1B Main will commence June 2024.


Each tranche includes a design, realisation, deployment and go-live phase and are scheduled to go-live in a staggered approach.
