Map relationships between elements
Mapping is the activity of identifying the relationships between elements either within a layer of an enterprise architecture or across layers of an enterprise architecture. Mapping helps practitioners understand the relationships between the organisation’s services and processes and the information, applications and technologies that support those services.
Mapping also helps identify any gaps and ensures the scope of information collected for the planning process is consistent. Where gaps occur, it may be necessary to adjust the information collected in line with scope of the planning engagement. This will provide greater focus on only those elements that are relevant to the planning engagement and will highlight any true gaps which may represent an opportunity to introduce new capability.
Mapping across layers is generally conducted from one layer to the layer above in an enterprise architecture. The extent to which mapping is conducted depends on the scope of the planning engagement and the information available. For planning purposes, it is recommended applications are mapped to the information they support. Underpinning technology assets and services should also be mapped to applications.
Refer to the Enterprise architecture mapping guideline for more information and resources.
Additional mapping such as information and applications to services or business objectives, can also be helpful to understand the importance of information and applications to support the business of the agency and its strategic intent.
