Design briefs become lifeless when we treat them as fixed, and unchanging.
We bring life to them when we allow them to evolve.
The first stage is to make your design brief a live, editable document (with changes tracked if necessary).
The brief should prompt questions – write those down on the brief.
New requirements will be discovered – add those in so they don’t get lost.
New possibilities for what you want emerge – note these down too.
Gather the people who care about the brief to review these changes, challenge or approve them.
A living brief is one that is being worked on.
