Make sure all the work your people are doing is essential to the organization. Set high standards. People won't generally perform above your expectations, so it's important to expect a lot. Lay the concept out, but let your people execute it. Tell them in the clearest terms what you want done, but let them suggest the best way to do it.
People come to work to succeed.
So don't operate on the principle that if they aren't watched and supervised, they'll bungle up the job. When in charge, take command. Some leaders who feel they don't have adequate information put off deciding to do anything at all. The best policy is to decide, monitor the results, and change course if it's necessary. Do what's right.
