I read this post and found it fascinating. While an internal memo from a mobile phone company might not sound too relevant, the message is one of change management. It very clearly illustrates a wonderful formula for change taught by one of our faculty members -- Horst Abraham of the Ross School of Business at the University of Michigan. Discomfort x Vision x First step = Change. It doesn't always require such a dire situation, but it's an important reminder that change always requires some pain.
