There are two basic ways to get people to do what you want: tell them and ask them. Actually, telling people is incredibly effective and works more often that you might expect. Tell is really the tool of the manager. I remember when I first became a manager (actually I received the badge of being a manager, it is not the same as doing management) the first question I had for my manager was: ‘how do I get people to do things?’ to which his simple answer was ‘just tell them’; it was my first lesson in effective communication! Unfortunately, a change manager is not a line manager so the tell option is not so effective and the ask option is much more likely to be used. How can a change manager ask people to change? The answer must be in the change manager’s ability to persuade people to change. Based on an article in the HBR by Robert Cialdini here are six Principles of Persuasion that can extend the persuasive powers of a change manager.
