There's some dope advice at the end: "I recommend you use predictions to become reliable. Whenever you make commitments, ask yourself am I at least 80% confident I'll follow through here? When I'm not, I renegotiate immediately: Actually I expect I can have that for you in 3 weeks, 1 was optimistic. Actually I can't commit to do that at all because I'm super focused on x and y right now. The earlier you reset expectations the better. It's pretty easy to get other people to clarify their commitments in the same way." Overall solid.

I definitely recommend the HBR article as well.
