Drop your mission and vision
Avoid the confusion between mission and vision. Here’s an example of two words that have been far too overused and mis-defined that they are almost not useful anymore. Instead, I go back to a model first introduced by Collins and Parras, 1996. Instead of vision and mission, try, yin and yang. Core values and core purpose represent the ideology [and the mission, if we must]. A big, hairy audacious goal (who came up with this term?) and a description of who you will be when you get there are the equivalent of your En[vision]ed future. A conversation about these components is a more neutral way to have a discussion about mission and vision.
