Many Processes to One Procedure

This relationship is used when several elementary processes have similar information views and are required by a common set of users.

An example of this case is shown in the following illustration.

In this example, three separate elementary processes are implemented by the same procedure. This is possible if the following two conditions are met:

The information required by the elementary processes is very similar. In the illustration, all three elementary processes probably require Customer Details.
The same set of users performs all the elementary processes under consideration. In other words, if one person is responsible for all aspects of Customer Maintenance, the arrangement depicted in the illustration is acceptable. However, if different people are responsible for adding, changing, and deleting customers, you should implement the three processes separately.
