# Set a performance budget

## When to use
Translate a slow experience into concrete budgets and a measurement plan.

## Workflow
1. Identify the user journey, target devices, network conditions, and current baseline.
2. Separate frontend loading, interaction latency, API time, and database work.
3. Choose measurable targets appropriate to the product.
4. Prioritize changes by observed impact and repeat the same measurement after changes.

## Boundaries
Use only tools and data authorized for the task. Ask for missing requirements when they affect the result. Report what you verified and what you could not verify.

## Try it
