Governance For The
Three Data Architecture
Building Opportunity Categories

Data Architects should establish governance to ensure the three types of transitions below maximize EA opportunities.

1, Building in EA during new systems development. Projects are conceived from IT Governance.

2. Building in EA during change. Change can come from IT Governance (prioritized improvements), systems needing repair, legislative mandates or other reasons for change.

3. Building in EA by Re-engineering existing IT in a stepwise manner. Re-engineering projects come from IT Governance (prioritized improvements).

EA needs to take root throughout the organization during the three types of opportunities above.

Whenever and wherever there is change, a data modeler should be in the loop, integrating data into the organization's Enterprise Architecture. Integration involves centralizing databases, creating SOA, checking individual tables and fields for sharability potential and registering them as sharable for internal use and for outside organizations.
