The Money Machine

What this pack runs.

A money machine is not a product with a good margin. It is a cross-subsidy with a meter on it: something sold at or below cost to acquire the customer, something else that earns on that customer at a multiple, and a rate that decides what the earning is worth. Companies audit the first two and almost never ask who sets the third, which is where money machines die. This pack names the three parts, distinguishes the four kinds of meter by who moves the rate, and computes how far that rate can move before the machine stops — a distance a board can govern, in place of a dependency it cannot.

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.
