High-powered teams function like the high-powered creative groups that produce Hollywood movies, says leadership guru Warren Bennis. Here’s how to build a Hollywood-style team of your own:Stress that people are coming together for a finite amount of time to work on a specific project. That builds a strong group identity.Promote the belief that the group functions without a hierarchical structure.Create a hothouse environment by stressing that the group’s goal is to produce something really exceptional. Talk in visionary terms about the goal so members develop a certain childlike innocence and optimism that what they’re doing is about to change the world. — Adapted from “Today’s Leadership: Focus on Great Groups,” Financial Executive.
