Inside the Build
XAF for enterprise speed
DevExpress XAF accelerated LOB delivery while maintaining enterprise patterns—security, auditing, and reporting out of the box.
Validation as UX
Inline validation reduced support tickets by catching errors at the point of entry rather than during downstream processing.
Operator-first design
Features were prioritized by daily usage frequency—high-traffic forms received the most UX refinement.
Lessons Learned
Parallel running with legacy processes built operator confidence. Incremental module rollout reduced change-management risk.
