According to the PMBOK® Guide and the Standard for Project Management, the Stakeholder Management Plan (referred to in the most recent editions as the Stakeholder Engagement Plan) is the primary input to the Manage Stakeholder Engagement process that provides the strategy for involving stakeholders.
As per PMI standards, the Stakeholder Management Plan is a formal document that identifies the management strategies required to effectively engage stakeholders. It provides specific guidance on:
Desired and current engagement levels: Identifying where stakeholders are (e.g., Unaware, Resistant, Neutral, Supportive, or Leading) and where the project needs them to be.
Scope and impact of stakeholder change: How the project affects stakeholders and vice versa.
Engagement strategies: Specific activities and approaches for involving stakeholders based on their power, interest, and influence.
The other options are incorrect based on their specific roles within the PMI framework:
Feedback analysis: This is a Tool and Technique (Data Analysis) used in the Monitor Stakeholder Engagement process to evaluate information received from stakeholders, rather than an input providing guidance for engagement.
Stakeholder analysis: This is a Tool and Technique used during the Identify Stakeholders and Plan Stakeholder Engagement processes to create the plan; it is not the plan itself.
Communication management plan: While this plan describes how information will be distributed (the " what, when, and how " ), the Stakeholder Management Plan focuses on the why and the behavioral strategies to ensure stakeholders are appropriately involved and supportive.
As per the PMI Lexicon of Project Management Terms, the Stakeholder Management Plan ensures that stakeholders are involved at the right time and in the right way to foster support and minimize resistance.
