# Meet the brain

A brain is a system built on your team's own method. It gathers the evidence, runs the models, compares the options and lays out the trade-offs.

Your people review and approve what happens next. You can adapt the method as your work changes.

**An example: the budget changes**

A client cuts the campaign budget. A brain built around your planning method could pull together the commitments, performance data and assumptions, then compare ways to spend what's left.

Your team reviews the options and their limits. Any action follows the permissions and approvals you've agreed. The decision and its outcome become part of the record you use to evaluate the method.

This is an illustrative use case, not a customer result. The first project tests whether the approach is useful in your work.
