Change wings on the fly
summary
Diggecard buys a UK gift-card business and must migrate 100+ customers in <1 year while guaranteeing zero downtime. The team builds a replacement incrementally: define end-to-end task flows (not UI clicks), create low-fidelity sketches, run cross-functional walkthroughs with product, tech and operations, then ship minimal end-to-end releases. Six legacy dispatch flows become merged into two task-level flows, the staged rollout meets the hard deadline and the replacement runs in production.
