The system that doesn't exist yet - the one your spreadsheet grew into - designed, built, and handed over with docs, tests, and runbooks so it's an asset, not a dependency on us.
- Product discovery: the problem, the users, the smallest right system
- Architecture sized to the team that will own it
- Delivery in shippable increments with demo cadence
- Handover as a feature: docs, tests, training, support window
