High-volume migration validation tool
The problem
An organisation needed a reliable way to compare outputs during a major system change, with teams reviewing a large volume of differences under time pressure.
What we built
A browser-based validation workflow for comparing structured exports, surfacing exceptions, filtering by issue type and helping reviewers work through discrepancies consistently.
What changed
- Differences made visible and reviewable
- Reviewers had a shared view of exceptions
- Manual checking replaced with a repeatable process
