...assumption...

Management therefore now has to start out with the assumption that there is no one technology that pertains to any industry and that, on the contrary, all technologies are capable- and indeed likely- to be of major importance to any industry and to have impact on any industry. Management similarly has to start with the assumption that there is no one given end use for any product or service and that, conversely, no end use is going to be linked to any one product or service.

Some implications of this are that increasingly the noncustomers of an enterprise -whether a business, a university, a church, a hospital- are as important as the customers, if not more important.
