Level of abstraction describes the breadth and depth of the information being provided. Representations of information may range from highly conceptual or summarized to very detailed. In determining how much detail each stakeholder may require as the initiative evolves, consideration is given to the needs of the stakeholders, the complexity of what is being explained, and the importance of the change. Rather than present the same information to all stakeholders, business analysts should present information with appropriate breadth and level of detail based on each stakeholder's role. Business analysis information regarding a topic of significant importance or high level of risk is frequently represented in greater detail.

Explanation
The stakeholder management strategy is generally not included in the stakeholder registry because it may contain sensitive information that should not be shared with project team members or certain other individuals that could see the stakeholder register. The stakeholder register is a project management document that contains a list of the stakeholders associated with the project. It assesses how they are involved in the project and identifies what role they play in the organization. The information in this document can be very perceptive and is meant for limited exchange only. It also contains relevant information about the stakeholders, such as their requirements, expectations, and influence on the project.
Answer D is incorrect. Stakeholder identification should be included in the stakeholder register.
Answer A is incorrect. Assessment information should be included in the stakeholder register.
Answer C is incorrect. Stakeholder classification should be included in the stakeholder register.
