The Flywheel

What this pack runs.

A flywheel is a claim that each turn makes the next turn cheaper, and most flywheel diagrams are a value chain drawn in a circle: nobody can say which output of one turn becomes an input to the next. This pack supplies the sentence that settles it, the one number that follows, and the two consequences of that number — because a loop with a gain below one converges rather than compounds. Additions settle at what you buy divided by one minus the gain, cost per customer settles at what you pay multiplied by one minus the gain, and both arrive within three or four turns, which means a company two years into running a loop is usually finished with it. It stops on two conditions: nobody can name the step, and customers the loop produced have never been separated from customers you bought.

The casebooks these cases come from.

The pack reads nine sourced decisions through the framework. They are drawn from these casebooks, each one a set of verified records on a single decision type.

A verified record has passed a mechanical claim-versus-source check, a second model's read, and human approval. The count is what exists today, not a target.
