Legacy processes in a regulated world
Lloyds Banking Group serves over 26 million customers across its consumer and commercial brands. At that scale, software delivery is not just an engineering concern - it is an operational risk that regulators watch closely.
When EAS engaged with the group, delivery teams were working with legacy processes that had accumulated over years of cautious, compliance-first change management. Release cycles stretched across quarters. Teams were siloed by function rather than aligned to outcomes. Developer onboarding took 77 days on average, a bottleneck that compounded with every new hire.
The challenge was not simply technical. It was cultural and regulatory. Any transformation had to move fast enough to deliver value, but carefully enough to satisfy the FCA, PRA, and internal risk functions at every step.
Core tensions
Speed vs. compliance
Moving faster without weakening the regulatory controls that protect 26 million customers.
Autonomy vs. governance
Empowering teams to own their delivery while maintaining central oversight and audit trails.
Innovation vs. stability
Adopting modern tooling and practices without destabilising systems that handle millions of transactions daily.
Culture vs. process
Shifting mindsets from gatekeeping and handoffs to ownership and continuous delivery.
Why banking DevOps is different
Financial services firms operate under a level of regulatory scrutiny that fundamentally shapes how software can be built, tested, and deployed. These are the constraints we designed around.
FCA and PRA Operational Resilience
UK banks must identify important business services, set impact tolerances, and demonstrate they can remain within those tolerances under severe but plausible scenarios. Every deployment pipeline we built was designed with this requirement in mind.
Third-Party and Cloud Governance
PRA rules require governance, risk management, audit rights, and exit planning for material outsourcings, including cloud infrastructure. Our Azure deployments included full compliance documentation and concentration risk assessments.
Change Management Controls
Regulated firms must maintain clear lines of responsibility and auditable change processes. Our CI/CD pipelines encoded approval gates, segregation of duties, and immutable deployment records directly into the toolchain.
Phased delivery, lasting change
We did not parachute in with a template. We embedded within engineering teams, learned the constraints, and built a transformation programme designed to outlast our engagement.
Assess and align
Weeks 1-6
- Mapped existing delivery workflows across business units
- Identified bottlenecks in release processes and change management
- Assessed regulatory constraints on deployment frequency and change control
- Defined target operating model for Agile delivery within FCA/PRA frameworks
Build the foundation
Weeks 6-16
- Designed and deployed CI/CD pipelines with automated quality gates
- Introduced containerisation for consistent environments across dev, staging, and production
- Implemented infrastructure-as-code for repeatable, auditable provisioning on Azure
- Established automated testing frameworks covering unit, integration, and regression
Scale and embed
Weeks 16-30+
- Rolled out Agile delivery practices across multiple engineering teams
- Coached squads on continuous improvement, sprint retrospectives, and DevOps ownership
- Scaled CI/CD patterns to additional business units and service lines
- Transitioned from consultant-led to team-owned, establishing lasting capability
What we delivered
CI/CD pipeline engineering
Jenkins-based pipelines with automated build, test, security scanning, and deployment stages. Every change tracked, every deployment auditable, every rollback instant.
Containerisation strategy
Migrating workloads to containers for environment parity across development, QA, and production. Eliminating the 'works on my machine' class of deployment failures.
Infrastructure as Code
Azure infrastructure defined declaratively and version-controlled. No manual provisioning, no configuration drift, no undocumented changes to production environments.
Agile delivery coaching
Embedded consultants working alongside engineering teams to introduce sprint planning, backlog refinement, and continuous delivery practices rooted in real delivery outcomes.
Automated testing
Comprehensive test suites running on every commit. Unit tests, integration tests, contract tests, and regression packs providing confidence that changes are safe to ship.
Change management and governance
Designing approval workflows and audit trails that satisfy FCA and PRA expectations without slowing delivery. Compliance built into the pipeline, not bolted on afterwards.
From quarterly releases to continuous delivery
Before
- Quarterly release cycles with manual deployment
- 77-day developer onboarding process
- Siloed teams with handoff-heavy workflows
- Manual provisioning and configuration drift
- Compliance as a separate, after-the-fact review
After
- Continuous delivery with automated quality gates
- Developer onboarding in under one hour
- Cross-functional squads aligned to business outcomes
- Infrastructure as Code with version-controlled provisioning
- Compliance encoded into CI/CD pipelines from day one
The transformation delivered measurably reduced delivery times and deployment risk. Agile ways of working were adopted across teams. The group shifted from quarterly releases to continuous delivery, all within FCA and PRA regulatory constraints. Most importantly, the changes stuck - teams owned the new practices long after the engagement ended.
“The goal was never to move fast and break things. It was to move fast and prove, at every step, that nothing was broken.”
