One of the prerequisites for setting up a webscorecard is that the business has a clear understanding of its strategy. A strategy can be defined without a mission, but it helps to set the direction by defining a mission.
The mission tells everybody what you are trying to do. It’s something that is true today and may be true for ever (or not).
The position in society is not always the motive for creating the business. Businesses may be started because the entrepreneur wanted to make money or because he likes to run the kind of business he is going to create.
But inconsient or not, a business must have a market to serve, in order to survive. They must offer some kind of benefit to that market. Therefore, I think that any organization tries to fullfill some need a person, group or the whole society may have.
The mission statement shows the purpose of the organization. You could say the mission statement is the description of how the organization will fullfill a need in society.
If business would be a battlefield, the mission would be the ideology for which you fight, the ultimate goal. It’s the outline for all the activities of the “army”
On my website www.webscorecard.nl I show how to write a missionstatement.
