The Challenge 

A transportation management system migration is never just a software swap. It touches every team that books a shipment, bills a customer, or answers a support call, and it does not forgive shortcuts. 

This client was moving off a decades-old legacy platform onto a modern cloud-based TMS, and the migration did not stop at the core system. Seven+ integration domains had to move in lockstep: the new TMS core, legacy TMS, a customer-facing portal, a partner and carrier portal, electronic data interchange order flows, a trucking dispatch system, a warehouse management platform, notifications management system and an accounts-payable and invoicing system. Each one had its own vendor, its own release cadence, and its own definition of done. 

Multiple delivery teams were building against this landscape at once, including an external systems integrator handling core development. Nobody owned testing across the seams. By the time formal System Integration Testing began, the picture of what was ready for go-live was fragmented across teams with no shared taxonomy for severity, no single defect intake process, and no consistent read on pace against the exit date. 

What the client needed was not another team writing test cases in isolation. It needed one team with the standing to see across every integration point, drive triage discipline into a defect backlog nobody had unified and tell leadership the truth about whether go-live was safe.

The stakes were high and specific: 

• A fragmented view of the whole. No single person or team understood the full end-to-end workflow, or how every event should behave as it moved from one system to the next.
• Real operational and customer risk. Every shipment depends on these systems working as one. Gaps could surface as delayed shipments, missed or duplicated customer notifications, billing and invoicing errors, or data that did not match between systems. 

The Solution 

UTurn embedded its Software Quality Engineering practice directly into the program's System Integration Testing effort. The mandate covered all seven plus integration domains: provide testing leadership across every vendor and delivery team touching the migration, coordinate execution sequencing against a fixed exit date, and own defect triage from intake through resolution. 

Test Governance and Program Infrastructure
UTurn built the governance layer the program was missing. Every defect surfaced during SIT was tagged, prioritized against a shared Blocker/High/Medium/Low taxonomy, and routed through a single intake process, regardless of which vendor or team owned the fix. A daily health digest tracked pass rate, execution pace, and days remaining against the committed exit target, giving program leadership a consistent, current read on risk instead of seven disconnected status reports.  

Coordinating Execution Across a Fragmented Integration Landscape
UTurn served as testing and review lead across all seven plus domains, which meant seeing patterns no single team could see on its own. A cluster of failures in the notification chain, for example, spanned four separate defects across three different systems: events not triggering outbound files, files sending but notifications never arriving, and status updates firing duplicate or incorrect events downstream. Traced individually, each looked like an isolated bug. Traced by one team watching the whole system, they pointed to a single integration gap in how status events propagated from the TMS core outward. UTurn's cross-domain visibility is what made that pattern visible, and what got it fixed once instead of four times. 

Automated Regression Coverage
Environment stability was never a-given. Every time the test environment changed, whether from a new deployment, a configuration fix, or a downstream vendor update, UTurn ran the full automated regression suite against it before SIT execution resumed. That discipline caught environment-introduced defects before they could be mistaken for new functional bugs. It also meant testers spent their time on genuinely new scenarios instead of re-validating work that had already passed.

Why UTurn 

Large TMS migrations rarely fail because nobody tested. They failed because everybody tested something different, with no one accountable for the whole picture. This program had an internal team, an external systems integrator, and a handful of third-party platform vendors all shipping into the same integration surface. What it did not have was a team with the authority to say what was actually ready. 

UTurn filled that gap. Not by writing more test cases than anyone else, but by taking ownership of the coordination layer: one defect taxonomy, one health signal, one team with visibility across every domain instead of seven teams each seeing their own slice. That crossdomain view is what turned isolated symptoms into diagnosable patterns, and what let the program commit to a go-live date with an honest answer behind it. 

What the client has now is not just a complete migration. It is a program delivered on schedule, with the confidence that comes from knowing every Blocker-severity defect was caught, triaged, and resolved before it could reach production.
