Manufacturers of many heavy-duty, engineered industrial products—such as gas turbines, electric drives, wind turbines and heavy trucks—derive most of their top-line revenues from their factory production, while the sweetest part of their bottom-line profits comes from aftermarket services. They have one company, and two different kinds of businesses.

In electrical contracting, a similar principle applies. New construction and service activities are not different magnitudes of electrical work; they are different kinds of business.
