What is a stakeholder register and what does it contain?

A stakeholder register is a project document that identifies all individuals, groups, and organizations that may affect or be affected by the project. For each stakeholder, it records their name, role, contact information, requirements, expectations, potential influence on the project, classification such as internal or external, and current engagement level. The register is developed during the Identify Stakeholders process and updated throughout the project as new stakeholders emerge or existing ones change roles.
