Build a growth model
The metric tree under your funnel, with the constraint identified.
Fill it in
Traffic, signups, activation, retention.
So a change anywhere shows its effect on the top.
The one stage that limits everything else.
Your prompt
Build the growth model. Draw the metric tree: the top number decomposed into the things that multiply to produce it, all the way down to something a team can act on. "Increase revenue" is not actionable; the leaf is. Use rates, not counts, at every node. Counts move with traffic and hide whether anything improved. Name the CONSTRAINT: the one stage where an improvement flows all the way to the top, and where everything else is currently wasted. Most growth work fails by improving a stage that is not the constraint, which changes the local number and nothing else. Model what a realistic improvement at each node is worth, so effort can be aimed.
Use Build a growth modelOpens with everything above already filled in.
Why this works
Most growth work improves a stage that is not the constraint, which changes the local number and nothing else. This draws the tree and names the stage that limits everything.
