EA Practitioners in the Enterprise Architect Role
In practice, the enterprise architect role can be but seldom is divided by the specialty areas into the sub-roles of governance architect role, organization architect role, integration architect role, compliance architect role, assurance architect role and enterprise management architect role.
When the enterprise architect role is divided into sub-roles, the enterprise architect role enables and assures these architect roles are integrated in their efforts so their architectures properly integrate and each also integrate with the other architectures within the enterprise.
It should be noted in practice, the enterprise architect role is often fully or partially combined with the business architect role or other architectural roles to provide an organizationally needed job (a “specialty”) to address special needs and other organizational needs and limitations of the organization.
