Sales metrics and rhythm

This is how we know whether selling works: what we count, what goes on the weekly dashboard, and which meetings read it. Stages and "qualified" are defined in the sales method chapter. Every target is a planning hypothesis until our own data replaces it. A metric whose data source does not exist yet is marked "measure when available", with the source it needs. While a number rests on fewer than 20 cases, show the count ("3 of 7"), never a percentage.
