For decades, service line growth was a reliable path to greater volume, revenue, and market relevance. That assumption is no longer universally true. Today, growth can expand the top line while eroding margin, straining capacity, and overextending the organization in markets where demand may not be obtainable or profitable.

This report outlines how leaders can avoid the volume trap and pursue service line growth that is financially durable, operationally feasible, and competitively grounded.
