7.2. Business vision view
A business vision view is a model of the business in terms of general
vision, the business language and the business motivation
Vision statement
A vision statement is a textual document expressing the main idea of the
business (at the current time and in the future)
An example
“We should be the leading supplier of office equipment and supplies.
We should offer customers attractive solutions and good value for their
money. By not going through a retailer, we cut the sales expenses.
Integrating our sales processes with our customers’ purchase
processes results in highly efficient communication and delivery. To be
able to integrate these processes, we must provide several interfaces,
such as Internet, e-mail, FTP, telephone, and fax. We can integrate
further by offering additional services such as inventory tracking and
automatic purchasing.”
