Feature blueprint
Let a signed-in user save useful items for later.
A user adds or removes an item from a personal saved list without changing the item itself.
Why this matters: Let a signed-in user save useful items for later.
In this lab, you’ll see how the smallest useful version connects the user action, app checks and saved outcome before the feature grows into a fuller product.
- 1User actionThe user begins the feature by giving the app useful input.
- 2App checksThe app validates the request before work continues.
- 3System processThe feature applies the core rule or workflow.
- 4Saved resultThe useful outcome is stored or made available.
- 5User outcomeThe user sees a clear result and can continue.
Context

Beginner build vs real product version
Beginner build
Toggle one account-to-item bookmark.
Real product version
Adds folders, notes, privacy, notifications, and cross-device synchronisation.
How it can grow
Once the beginner version works, the upgrade path is about making the workflow more resilient, reviewable and useful in a real team.
- Add stronger validation, permissions, monitoring, and operational review.
Watch out for
- Building every edge case before the smallest useful workflow works.
