Our core banking modernization will place us well ahead of our competitors. The new architecture behind the SAP platform gives us the power to treat IT as a utility.

Deployment country


The Commonwealth Bank of Australia (CBA) is Australia’s largest financial institution, serving with a full-time staff equivalent of more than 37,000 approximately 7.7 million customers in 1,011 branches and operating 3,350 ATMs. The group has also businesses across New Zealand, Fiji, Asia, USA and the United Kingdom.

Business need
The Commonwealth Bank Group is undertaking a comprehensive program to modernize its existing banking systems building a customer centric platform that enhances the way the Group provides services to its customers and the way it does business. The goal is to make customer banking experience simpler and more efficient, underpinned by excellent end-to-end processing systems.

The Group has selected SAP for Banking solutions based on SAP NetWeaver®. The solution portfolio provides banking-specific (transactional banking, CRM, risk management) as well as banking-relevant (financial accounting, human resources management, procurement) services and solutions created on a single enterprise service-enabled business process platform.

The Commonwealth Bank of Australia decided to move their core banking operations to the SAP for Banking platform in order to offer excellent customer service. Their focus on IT included reorganization and efficiency efforts which generate high savings. Therefore the IBM System z architecture behind the SAP platform was chosen as reliable and secure technology that supports continuous availability of systems. Disaster Recovery (DR) is a critical component of IT and risk mitigation strategies, compounded in difficulty by ever growing data volumes, distributed computing and new technologies.
