Leaders have a clear vision, they communicate that vision and inspire others to go with them. Implementing new technology oftens fails because people are not committed and opt out of the change the moment anything diffficult comes up. The post from Seth Godin below refers to this problem.
…people are quick to opt out of the we part. “What do you mean, we?” they ask. Its so easy to not be part of we, so easy to make it someone elses problem,…Successful people rarely confuse a can-do attitude with a smart plan. But they realize that one without the other is unlikely to get you very far.
