Why is it a mistake?

Recommendation for the vision. The first recommendation of a strategic plan is the vision, which looks externally and explains-without mentioning the organization or its offerings-how the organization will make the world a better place. An example is, "We see the world free of infectious disease." The vision ought to motivate and guide the employees, as is true of the example above. An overly broad vision provides no guidance; an example is, "We see a world in which all needs are satisfied." Other common mistakes with the vision are: - it is not a description of a better world - it includes the organization's industry, offerings or actions. Justification of the vision. None is required, but if you think the reader might not understand, you ought to explain why it looks externally and how the organization will make the world a better place
