- Any proposed feature must solve a core problem (see terminology).
- A core problem must be proven legitimate via user testing.
- A milestone complete when it's milestone tests are passed via user testing.
- Milestone tests must be defined before any development or design occurs.
Milestones
-
A milestone solves some set of core problems.
-
A milestone test is a set of tests that must pass for a release to be considered reached. These usually involve user testing.
-
Milestone planning is the act of (1) choosing a set of proven problems to solve for, and (2) defining tests to measure if they have been solved.
Core Problems
-
The Core problems are an ordered list of problems we're attempting to solve. Every problem must have convincing evidence of its suggested severity and urgency. Likewise, user tests must be shown for a release to be considered ready.
-
The Core Problem Dashboard is an explicit list of the problems we're trying to solve, what order we plan to solve them in. Absorb this, question this, know it. This is our map for navigating features and priorities.
