## FAQ

### When should I use Milestone?

Use it when the team needs to decide scope, priority, owner, or trade-off, not when it only needs a short definition.

### What makes Milestone useful in practice?

It becomes useful when it is tied to evidence, a decision owner, and a concrete next operating choice.

### What should I avoid?

Avoid using the term as a label without clarifying assumptions, boundaries, and how success will be judged.
