Specifying Business Systems to CA Gen

Review the clustered Entity Type/Elementary Process Matrix. After you have addressed all anomalies and firmly defined all clusters, you can define the business systems in CA Gen.

Tasks for defining business systems in CA Gen include:

• Give each business system a name.
• If names have not yet been specified for the business systems discovered during cluster analysis, they must be invented now.
• There are no firm rules governing the formulation of business system names. Simply choose words that express the function of the system.
• Select the elementary processes that each named business system will implement.
• Use the clustered matrix to identify the elementary processes belonging to each business system, bypassing any that were not selected for implementation.

Developers specifying business systems to be implemented in a client/server environment may find that:

• Processes that are closely clustered by their creation and maintenance of data that is widely used by many other processes are candidates for support by business systems that include server procedures that can be used by many client procedures.
• Processes that need many entity types (possibly created by several different clusters) are candidates for support by business systems composed of client procedures that reuse data maintained by a combination of current systems and provided by common server procedures.
