When you’re leading a Professional Services firm, pay attention to the mix of revenues from the mix of your services:
Pass Through Services vs Direct Services vs Productized services (IP).
The margins are increasingly attractive as you move across from pass through to IP. The relationships may arguably be strongest when you’re delivering your direct services reliably over a period of time.
What the ideal mix is for your firm depends on your strategy and the unique demands of the clients you serve. Decide on it, dashboard it and manage to it.
