Domain coupling
The term for that kind of forced coupling is connascence. Two components are connascent when a change in one forces a change in the other. Connascence Degree is the count of unrelated modules that have to change together with the main one for a given change. A high Connascence Degree shows that a single change is forcing many others to move with it.
The report trains coupling from this company's finished changes. When there is nothing to train on, or that result is not positive, each extra part adds half of the change's own hours. The dollars are domain coupling: unrelated parts of the product forced to change together.
