Here's a good definition of the difference between a mission and a vision by leadership book authors George Bradt, Jayme A. Check and Jorge Pedraza:
- Mission - A mission guides what people do every day. It informs what roles need to exist in the organization.
- Vision - A vision is the picture of future success. It helps define areas where the organization needs to be best in class and helps keep everyone aware of the essence of the company.
