Talk to individuals. Ask what kinds of problems they have with “teaming.” When an organization is having trouble with change, managers usually say they know what is wrong. But the truth is that often they don’t. They imagine that everyone sees things as they do, or they make assumptions about others that are untrue. You need to ask the right questions. If you ask, “Why aren’t you doing this?” you’ve set up an adversarial relation and will probably get a defensive answer. If, on the other hand, you ask, “What problems are you having with this?” you’re likelier to learn why it isn’t happening.
