The purpose of the System/Function matrix is to depict the relationship between systems (i.e., application components) and business functions within the enterprise.

Business functions are performed by organizational units. Some of the business functions and services will be supported by IT systems. The mapping of the Application Component-Function relationship is an important step as it enables the following to take place:

• Assign usage of applications to the business functions that are supported by them
• Understand the application support requirements of the business services and processes carried out
• Support the gap analysis and determine whether any of the applications are missing and as a result need to be created
• Define the application set used by a particular business function

The System/Organization matrix is a two-dimensional table with Logical Application Component on one axis and Function on the other axis.

The relationship between these two entities is a composite of a number of metamodel relationships that need validating:

• Function is bounded by Service
• Services are realized by Logical/Physical Application Components
