About the project

Our solution

The Customer: Who they are

An omnichannel retail chain building a new internal platform to unify online and in-store commerce data for its operations teams.

The Challenge: Identifying the villain

A previous attempt at a similar platform, built by a different vendor, had shipped with minimal testing and generated a wave of production incidents that eroded trust in the whole initiative. “The business had already been burned once,” said the Head of PMO.

The Journey: The search for a solution

The retailer initially looked for a pure development shop to rebuild the platform quickly, but leadership was wary of repeating the same testing gap that caused the last failure.

The Discovery: Finding IDS

IDS was shortlisted specifically for its “Build / Validate / Manage” delivery model — testing embedded from day one rather than bolted on at the end.

The Solution: The hero arrives

IDS delivered full-stack development (Java backend, React front end) with a dedicated QA workstream running in parallel from the start — functional, regression, and performance testing built into every sprint — under a single programme manager accountable for scope, timeline, and quality together.

The Implementation: The battle

Delivery ran in two-week sprints with automated regression suites via Selenium expanding alongside new features, so quality didn’t degrade as functionality grew. The obstacle: integrating with a fragile legacy POS API; IDS built a resilient adapter layer with contract tests to catch upstream changes before they broke production.

The Results: The happy ending

  • Delivered on original timeline and budget 
  • Post-launch defect rate: significantly lower than the prior attempt 
  • Automated regression coverage: 80%+ of critical user flows 
  • Full knowledge transfer completed, internal team self-sufficient post-handover

“This is the first platform project that didn’t blow up in year one.” — Head of PMO
