The factory model behind mass migrations
FPT Software's factory: find the patterns, group the applications, run each group the same way. NGT sizes it per programme.

- 02Solution enablementAn architecture review board, solution design and a reference architecture per migration pattern.Architecture review boardReference architecturesKnowledge management

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 owners✕Only IT involved; gaps found at user acceptance✓Owners review results from the first wave
The assessment✕A one-off report that goes stale✓A living document, checked every wave by the review board
Business knowledge✕Lost when screens and processes change✓Knowledge transfer planned as real work
Ownership✕Nobody clearly owns an application✓Three owners: business process, application, operations
Countries✕Silos repeat the same work in each country✓Dedicated squads and a shared knowledge network
Tools✕A tool chosen before the patterns✓Shared services, hub-and-spoke and patterns first
