To program is to understand: The development of an information system is not just a matter of writing a program that does the job. It is of utmost importance that development of this program has revealed an in-depth understanding of the application domain; otherwise, the information system will probably not fit into the organization. During the development of such systems it is important that descriptions of the application domain are communicated between system specialists and the organization.
