## User Scenarios & Testing *(mandatory)*
|
||||
## Purpose
|
||||
|
||||
<!--
|
||||
IMPORTANT: User stories should be PRIORITIZED as user journeys ordered by importance.
|
||||
Each user story/journey must be INDEPENDENTLY TESTABLE - meaning if you implement just ONE of them,
|
||||
you should still have a viable MVP (Minimum Viable Product) that delivers value.
|
||||
|
||||
Assign priorities (P1, P2, P3, etc.) to each story, where P1 is the most critical.
|
||||
Think of each story as a standalone slice of functionality that can be:
|
||||
- Developed independently
|
||||
- Tested independently
|
||||
- Deployed independently
|
||||
- Demonstrated to users independently
|
||||
-->
|
||||

|
||||
|
||||
