The 7 Styles of Enterprise Architecture Governanceposted by Anna Mar, June 02, 2011
There are 7 common models of EA governance. The difference centers around one question: who has decision making authority?
1. ChiefdomThe chief architect has strong decision making authority — supported by a hierarchy of enterprise architects.
2. IT MonarchyA council of IT executives calls all the shots.
3. Business MonarchySenior business leaders (possibly Cx0 level) make the decisions.
4. DuopolyA mix of business and IT executives exercise authority.
5. DemocracyIT and business groups nominate representatives (often silo architects) to sit on a voting architecture council.
6. CommunismA team of administrators has decision making authority (usually limited to standards compliance).
7. AnarchyNo one has clear authority — they just fight it out.
What is the best approach?The best approach depends on the nature of the organization:
|•||a chiefdom works well when you have a brilliant chief architect who has the authority to drive change.|
|•||a democracy works well when you have feuding IT and business groups or lack strong executive leadership.|
|•||a Duopoly can help strengthen business-IT alignment.|
