Score every idea the same way
- Expected effect: how big a change the idea could make on the number that matters, from 1 (small) to 3 (large).
- Cost to run: the budget, production time and approvals, from 1 (cheap) to 3 (expensive).
- Evidence: 1 if the idea is a guess, 2 if a related test or a store signal supports it, 3 if the team has measured it before.
Rank and pick
- Multiply effect by evidence, then divide by cost. Sort the list by that number. Simple arithmetic is enough.
- Take the top idea and check that it can finish inside the test window with the budget you have.
- Put the rest on the backlog with a date to look at them again.
What to leave out
- Ideas with no clear measure. If nobody can say which number should move, the test cannot end.
- Ideas that repeat a test that already ended, unless the first one was too small to read and the note says so.
- Ideas that need a change the client has not approved. Those wait for approval, they do not jump the queue.
Made-up scenario: a made-up skincare team scores two ideas. Idea A, a new opening line for the top video, has effect 3, evidence 2 and cost 1, so it scores 6 and goes first. Idea B, a new product shoot, has effect 3, evidence 1 and cost 3, so it scores 1 and waits for next month.
