A high-visibility project with medium complexity requires careful time management to ensure that the project is delivered on schedule. The project manager should focus on planning, setting deadlines, and monitoring project progress1. Stakeholder engagement is also crucial in this scenario. The project manager needs to communicate effectively with all stakeholders to understand their expectations and keep them informed about the project's progress23. This includes initiating regular status meetings and developing a clear communication protocol4. References: Coursera, The Digital Project Manager, Adobe, Project Central, Microsoft

Defining a minimum viable product (MVP) is a core concept in delivering value early and continuously, which aligns with the agile principles of project management. An MVP allows the project manager and stakeholders to understand the product's vision more clearly by focusing on the core functionalities that will meet the customer's needs and provide immediate value. This approach also facilitates early feedback, which is crucial for iterative development and continuous improvement.
The answer is verified using the PMP Examination Content Outline, which emphasizes the importance of delivering value and involving stakeholders1. Additionally, the PMBOK Guide standards highlight the need for project managers to engage stakeholders and meet project objectives2. The Professional in Business Analysis Reference Materials also support the use of an MVP as part of the business analysis process to maximize value delivery and stakeholder engagement3.

The stakeholder register is a project document that identifies and classifies the project stakeholders, their roles, interests, expectations, and influence levels. It is an output of the Identify Stakeholders process, which is the first process in the Project Stakeholder Management knowledge area. The stakeholder register should be updated whenever there are changes in the project environment or stakeholder information, such as a promotion, a change of role, or a change of contact details. Updating the stakeholder register will help the project manager and the project team to communicate effectively and appropriately with the stakeholders, and to manage their expectations and engagement levels throughout the project life cycle.
The project management plan is a comprehensive document that describes how the project will be executed, monitored, and controlled. It integrates and consolidates the subsidiary plans and baselines from the different knowledge areas, such as scope, schedule, cost, quality, resources, communications, risk, procurement, and stakeholder management. The project management plan is an output of the Develop Project Management Plan process, which is the second process in the Project Integration Management knowledge area. The project management plan should be updated only when there are changes in the project scope, objectives, deliverables, or approach, and when these changes are approved through the Perform Integrated Change Control process. Updating the project management plan for a stakeholder promotion is not necessary, unless it affects the project scope or other aspects of the project.
The stakeholder engagement plan is a subsidiary plan of the project management plan that describes the strategies and actions to increase the support and minimize the resistance of the stakeholders throughout the project. It is an output of the Plan Stakeholder Engagement process, which is the second process in the Project Stakeholder Management knowledge area. The stakeholder engagement plan should be updated when there are changes in the stakeholder engagement levels, needs, or expectations, and when these changes are approved through the Perform Integrated Change Control process. Updating the stakeholder engagement plan for a stakeholder promotion may be required, depending on how it affects the stakeholder's interest, influence, or power over the project.
The communications management plan is a subsidiary plan of the project management plan that describes the communication methods, formats, frequency, and responsibilities for the project. It is an output of the Plan Communications Management process, which is the first process in the Project Communications Management knowledge area. The communications management plan should be updated when there are changes in the communication requirements, preferences, or channels of the project stakeholders, and when these changes are approved through the Perform Integrated Change Control process. Updating the communications management plan for a stakeholder promotion may be necessary, depending on how it affects the stakeholder' s communication needs or preferences.
Therefore, the correct answer is C. Stakeholder register, as it is the most relevant and appropriate document to update for a stakeholder promotion.

For a project manager overseeing a customer experience project where customer satisfaction is a significant issue, it is crucial to first confirm the existence of the issues reported by customers. Conducting a survey and other analyses helps in understanding the root cause of the customer queries and ensures that the solutions provided are targeted and effective. This approach is supported by the PMBOKGuide, which emphasizes the importance of accurate data collection and analysis for project decision-making1.
Once the issues are confirmed, deploying solutions that can track, prioritize, and resolve queries promptly is essential. This aligns with the principles of effective project management and business analysis, which advocate for the use of tools and techniques to manage and address stakeholder concerns efficiently23. By implementing such solutions, the project manager can ensure that the customer service team is not overwhelmed and that customer satisfaction is improved.

The project manager should evaluate the consequences and meet with the client to explain the possible scenarios. This is because the project manager needs to balance the competing demands of scope, time, cost, quality, and stakeholder satisfaction. The project manager should not hire the resource without the client's approval, as this would violate the terms of the contract and the trust relationship. The project manager should not ask the client for a meeting and explain that the task will not be performed, as this would compromise the project objectives and quality standards. The project manager should not try to accomplish the task internally by leveling resources from other projects, as this would create risks and dependencies for both projects and potentially affect their performance. The project manager should evaluate the consequences of not hiring the external resource, such as the impact on the project schedule, quality, scope, and risks. The project manager should also identify alternative solutions, such as negotiating with the client, finding another resource, or modifying the project plan. The project manager should then meet with the client and explain the possible scenarios, highlighting the benefits and drawbacks of each option. The project manager should seek the client' s input and feedback and try to reach a mutually agreeable solution that satisfies the project requirements and the client's expectations.
