The Challenge
Making DevOps real at enterprise scale
Despite recognising the need for DevOps, the organisation was struggling to make it stick. Many teams believed it wasn’t feasible in a highly regulated, complex environment and progress was being stifled by bureaucracy and fragmented operating models.
Key challenges included:
– Widespread scepticism about DevOps viability within a traditional enterprise
– 45,000 IT staff spread across global locations, with little shared alignment
– Siloed structures that limited collaboration and slowed delivery
– Bureaucratic processes blocking change and innovation
To succeed, the bank needed more than just tools. It needed a cultural and structural shift
The Solution
Empowering teams. Removing blockers. Scaling success
Catapult’s Transform team launched a targeted DevOps change programme to shift mindsets, re-structure delivery teams and accelerate the adoption of modern engineering practices.
Key solution components included:
– DevOps Bootcamp. Used to spark mindset change and build belief in new ways of working
– Team Restructure. Created 2,000+ cross-functional DevOps teams, each focused on a single customer journey
– Collaboration Platform. Built to help specialists across disciplines stay connected and share knowledge
– Bureaucracy Reduction. Identified and eliminated unnecessary governance layers slowing decision-making
– Tooling and Automation. Rolled out automated workflows and DevOps toolchains to support fast, secure delivery
The Results
A transformed delivery model with measurable business impact
Catapult helped turn DevOps from a buzzword into a sustainable, scalable delivery model. One that’s still delivering results.
The new operating model helped unify dev and ops, empowering teams to deliver faster, more reliably and with significantly less waste.
Key outcomes included:
– 2,000+ DevOps teams stood up across the organisation
– 10,000 users onboarded to DevOps tools in just 12 weeks
– Cycle time cut from 90 days to 15, accelerating delivery dramatically
– Change request touch time reduced from 40 hours to 15 minutes
– 4,500 hours saved per year in one business unit alone
– 23% reduction in rework on change requests through improved collaboration
