The decision

What this pack runs.

Ask how a price rise was arrived at and the answer is a margin target, an inflation figure or a competitor's list price. Ask what the last rise cost in volume and the room goes quiet — and that number is in the company's own history, an afternoon away. This pack produces both halves of the decision: the share of volume the rise can afford to lose, which is arithmetic on the rise and the contribution margin, and the share your own last rise says it will lose, which is one real rise measured against the trend that preceded it. It returns the gap between them in points of volume, the highest rise your evidence supports, and the first year against the steady state where volume is contracted — because contracts do not prevent the walk, they choose the year it lands in. It stops on two conditions: no past rise has been measured against volume, and no contribution margin exists for the line the rise applies to.

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.
