Transforming legacy software
summary
Legacy code causes cognitive overload and builds up emotional debt that blocks change, so a dedicated multi‑disciplinary team forms, applies stricter WIP limits, deliberate slack, a single front door, office hours and a Technical Design Authority, breaks work into thin vertical slices with the elephant kacho model, and reduces context poisoning. Proof of concept ships in 3 days, first milestone in 4 weeks, and an end‑to‑end rebuild delivers in 6 months. Biases targeted: anchoring, law of the instrument, optimism and sunk‑cost.
