Next, remember that your job has changed in some big ways. As his manager, you may now have the ability to override his decisions, but use this power very cautiously. Using your managerial power to override technical decisions is usually a bad idea. Resist the temptation to micromanage people — especially those who used to be your peers. They’re going to be sensitive to the feeling that you’ve been “rewarded,” even if they didn’t want to become managers themselves. If you question their every move and try to make every single decision yourself, you’ll make this sensitivity much worse.
