Case Study: Strengthening a Critical Data Platform
The Context
DAL operates a complex data platform that supports essential internal services across the organisation. Working in a regulated environment, the priority was not replacement, but making the existing platform stronger, safer, and easier to maintain while live services continued uninterrupted.
The Challenge
As the platform evolved, several pressures became clear:
Key internal components, including a custom caching capability, were still at prototype stage
A large shared codebase had become difficult to navigate and onboard into
Documentation existed, but it was fragmented and inconsistent
Responsibility for critical systems sat with too few individuals
At the same time, DAL needed to protect service continuity and reduce delivery risk.
Our Approach
We embedded Turntabl engineers directly into DAL’s delivery teams, working day to day within existing processes and governance. Initial efforts focused on moving a prototype internal capability closer to production readiness, before priorities shifted toward the areas most critical to platform stability.
A major focus was DAL’s notification systems, which support day-to-day operational workflows. We improved reliability, resolved long-standing issues, introduced enhancements for new use cases, and strengthened monitoring and observability so issues could be identified earlier. In parallel, we supported infrastructure and cloud upgrades, delivering changes carefully and testing thoroughly to avoid disruption.
The Results
A production-ready notification service now used daily across the organisation
Improved reliability and operational visibility across core systems
Successful delivery of high-risk infrastructure upgrades with minimal impact
Greater resilience through improved documentation and shared understanding
The Impact
Rather than pursuing a disruptive transformation, DAL strengthened what it already had. The platform is now more reliable, easier to operate, and safer to change. Internal teams have better visibility into system behaviour, and knowledge is shared more widely across the organisation.
By embedding as long-term partners and focusing on practical, incremental improvements, Turntabl helped DAL improve the resilience of a critical platform while maintaining dependable services in a regulated environment.
