Challenge

Our client is one of the largest financial institutions in Australia. The bank employs more than 30,000 people, serving 9 million customers, at over 900 locations. In 2020 the client launched an ambitious cloud migration program in partnership with Microsoft that involved the migration of hundreds of legacy applications to public cloud. The program set out to accelerate the bank's adoption of cloud services to deliver increased resilience and reliability, reduced risk & cost, and drive business advantage. It was to pave the way for future innovation by focusing on the user experience and become a beacon to attract the best cloud skills that could deliver new ways of working for the bank.

The challenge for DigiRen

To accelerate the bank's adoption of cloud services by providing executive delivery leadership throughout the migration program.
