| # Business cases The business case approach provides clear insight into the interaction between business functions. A business case indicates how a request from the outside world is subsequently handled by the various business functions inside an organization to fulfill a request. Each business case is shown in a BCD on the main-function level. The route followed by the business case is visualized by means of sequence numbers that are related to the request triggers. The business case approach starts with an initial request and progresses through the main function or the function’ s variant that is required to fulfill the request. The major functions to which the main functions in the case belong are shown in the background of the BCD to have reference to the top level BCD. Functions that are not required by a particular business case are not included in the BCD. |
