Ben Casnocha has a long, excellent piece entitled 10,000 Hours with Reid Hoffman: What I Learned, in which he shares a bunch of lessons he learned from then LinkedIn founder:

A lot of strategists (and CEOs) think that their job is to conceive a strategy and then hand it off to the underlings to execute. They might concede that delegation matters, but usually as a matter of execution more than strategy.

Reid disagrees. He once told me, “Whoever is actually immersed in the actual execution of a strategy should always think of ways to tweak the strategy for the better.” It’s a litmus test for talent: How do you know if you have A-players on your project team? You know it if they don’t just accept the strategy you hand them. They should suggest modifications to the plan based on their closeness to the details. And as they execute, they should continue to tweak the strategy, and you (the owner) should not feel a need to micromanage or second guess—if you do, you’ve got the wrong person.

The whole piece is full of wonderful gems like that. Highly recommended read.
