Brief once, refer back forever
Write the brief inside the campaign. Creators read the same brief you wrote. No more "which version of the doc are we on?"
Direction tied to the frame
Tell a creator what to change at the exact second you mean. Strategists stop translating timecodes into prose and creators stop guessing what you meant.
A revision history you can learn from
Look back at how a deliverable evolved across versions. Patterns become visible and your next brief gets sharper.
