Which document outlines the roles and concerns of stakeholders in an architecture engagement?

The Stakeholder Register is a critical document in an architecture engagement as it serves to identify and outline the roles, concerns, interests, and impact of various stakeholders on the architectural project. It captures detailed information about each stakeholder's influence and their potential contribution to the architecture process, enabling better engagement and management throughout the project lifecycle.

By having a structured approach to documenting stakeholders, the Stakeholder Register facilitates effective communication and helps to ensure that their needs and concerns are adequately addressed. This is essential for achieving stakeholder buy-in and for the overall success of the architecture initiative.

While other options may involve aspects related to stakeholders, they do not provide the same level of comprehensive detail about roles and concerns. For instance, a Stakeholder Map visualizes the relationships and influence of stakeholders but does not capture detailed roles. A Business Scenario outlines specific business needs and context but does not specifically detail stakeholder concerns. The Risk Management Plan focuses on identifying and mitigating risks within the project but does not concentrate specifically on stakeholder roles and concerns.
