Lessons learned from mass migrations

What FPT Software's programmes learned the hard way, and what NGT now does from day one.

What went wrong What NGT does now
Application ownersOnly IT involved; gaps found at user acceptanceOwners review results from the first wave
The assessmentA one-off report that goes staleA living document, checked every wave by the review board
Business knowledgeLost when screens and processes changeKnowledge transfer planned as real work
OwnershipNobody clearly owns an applicationThree owners: business process, application, operations
CountriesSilos repeat the same work in each countryDedicated squads and a shared knowledge network
ToolsA tool chosen before the patternsShared services, hub-and-spoke and patterns first
