The Challenge

Rising costs and an inflexible banking platform.

A FTSE 100 retail bank faced rising costs of change and a lack of agility in servicing their 21st century customers. A complex programme was initiated to build a new, secure, and scalable banking platform capable of servicing the bank’s customers in a modern era, beginning with a migration of 250,000 customers. Transitioning from legacy ways of working and processes in a large organisation was set to be a big challenge and support was needed to establish greater confidence in delivery.

The Solution

Building a cloud-native banking platform on GCP.

We worked closely with Google and the bank to develop the business case and cloud consumption model.

We then defined the high-level solution architecture and drove initial programme planning and prioritisation. As a trusted, independent delivery partner, we filled key programme delivery roles leading diverse, multi-supplier teams. We also provided cloud architecture expertise to advise on strategic design decisions, drove architectural best practice, and led the Technology Office function across the programme.

Our Engineering function provided a quality assurance layer to drive continuous improvement and developer best practice, which would help to maximise the potential of the development teams.

The Results

Live MVP launched within nine months.

From programme mobilisation, it took just three months to launch a live beta Google Cloud Platform - a key early proof point providing the confidence to proceed to the next stage of funding.

To follow, we successfully navigated considerable challenges to launch a customer MVP within nine months.

We also transformed the organisation’s approach to software delivery, embedding continuous improvement processes and a mindset of embracing change - something that we have seen take root more widely across the organisation.
