A practical cut of Retail: Architecture Playbook for engineering and product leads — decisions first, framework essays last.
Who this is for
Ship a thin vertical slice, measure, then widen. Big-bang rewrites rarely survive the first month of real traffic.
Decisions that still look smart in 18 months
Teams that write trade-offs down before coding burn fewer sprints when a stakeholder changes their mind mid-build. We keep ADRs short on purpose.
Build checklist we actually use
Instrument the happy path and the ugly path. Silent failures are what turn a launch into a weekend incident.
Failure modes we keep seeing
Use boring technology where the risk is operational. Save novelty for the one wedge that makes the product worth buying.
How we measure rollout

We update this when delivery patterns change on live client work.
