As part of the effort to establish and understand who should be part of the review and decision making process of establishing and building an enterprise architecture, you can build a Stakeholder Relationship Map. In a Stakeholder Map, you list the parties in the organization who have interest in the EA, and their ability to effect the EA. This is information that you use as part of your EA planning; not necessarily information you need to publish to the entire organization.
System Architect provides matrices for mapping Stakeholders to the effect they can have on the EA, and to the parts of the EA they influence. Access control enables you to keep this information restricted to usage by the EA team and the management involved.
With TOGAF turned on as a Framework, two matrices become available and are accessible by selecting View > Matrix Browser – the Stakeholder Map Matrix, and the Stakeholder Position Matrix.
