What we check early on Ecommerce: Data Model Guide, what usually goes wrong in production, and how teams avoid a rewrite six months later.
Who this is for
Instrument the happy path and the ugly path. Silent failures are what turn a launch into a weekend incident.
Decisions that still look smart in 18 months
Ship a thin vertical slice, measure, then widen. Big-bang rewrites rarely survive the first month of real traffic.
Build checklist we actually use
Use boring technology where the risk is operational. Save novelty for the one wedge that makes the product worth buying.
Failure modes we keep seeing
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.
How we measure rollout
Ignore the buzzwords. For Ecommerce: Data Model Guide, the hard constraint is usually data ownership or ops capacity — not how many features fit on a roadmap slide.
We update this when delivery patterns change on live client work.
