The challenge
The client's EDI ran on an end-of-life translator. Maps were undocumented, partner onboarding took weeks, and failures surfaced only when a customer called.
What we did
- Inventoried every trading partner, message type and map, and ranked them by volume and risk
- Rebuilt maps on the new platform with regression tests against a year of production traffic
- Cut partners over in waves, with parallel runs and a rollback plan for each wave
- Added alerting and a partner dashboard so failures are fixed before they become calls
The outcome
Partner onboarding dropped from weeks to days, and the support team now sees failed messages within minutes instead of hours.
