It’s pretty easy to identify the work that ought to be outsourced. But some work is different. Some work defines you. It’s the thing people talk about; it’s the the reason they come to you instead of your competitor. Sure, you can hand it off, but you run the risk of sub-optimal results. You run the risk of losing the thing that keeps people referring to you, coming back to you, or saying nice things about you: your secret sauce.
