Driver tree

A maths version of an issue tree.

A driver tree breaks a number into the numbers that multiply or add up to it. Revenue = users × orders per user × order value.

It shows exactly which lever moves the result most.

How to break it down

Revenue

Users

× Orders per user

× Average order value

🧮 Example

Revenue fell 10%: users flat, orders per user −15%, order value +6% → the problem is frequency.
