Rosa Say, at Talking Story, discusses "What’s the Difference Between Mission and Vision?"
She comments: "At times I run across companies which don’t bother to distinguish them at all: They have a separate Values Statement (thank goodness), but if you ask them to tell you of their Vision, and then of their Mission, they’ll give you the same answer for both questions. So what is the difference?
Does it matter?"
BOTTOMLINE: The short answer is that it only matters if you use them. Make them both available and accessible to everyone in the organization - every day.
