Flash back five years, when fees stood at $2.2 billion (remember, they are now at $3.5 billion). Since then, business on a pure dollar basis has expanded 59 percent—a heck of a run in any industry. Another interesting stat: Firms are getting more out of their designers than ever before, as fees per employee topped $300,000 for the first time, up 15 percent. (Staffers report that 80 percent of their time was billed to clients.) Sweet numbers, indeed.
