There is a gap in most Vision work.
Most companies start with what they want to become. That is incomplete. Vision starts with the spark of a big idea, but it only becomes powerful when others can feel the problem and believe in the possibility.
A weak Vision sounds inspirational but travels nowhere. People may call it interesting, but they do not retell it, fund it, buy into it, or organize around it.
The Vision Gap appears when the company has ambition but not an emotionally clear future. The team may know what the company does, but not what world the company is trying to make possible.
