According to the PMBOK Guide, team-building activities are one of the tools and techniques for managing project teams. Team-building activities help enhance project performance by improving team morale, reducing conflicts, increasing trust, and fostering collaboration. Team-building activities can be formal or informal, and can be conducted throughout the project life cycle. Some examples of team-building activities are icebreakers, workshops, retreats, celebrations, and recognition programs. By planning to implement team- building strategies throughout the project, the project manager can avoid the challenges related to team motivation that were encountered in a similar, previous project.

The project manager should follow the project escalation policy and communications management plan to address the situation of reduced cost and shortened schedule due to changes in EEFs. EEFs are external factors that can influence the project performance and outcomes, such as market conditions, government regulations, organizational culture, etc. When EEFs change, the project manager should assess the impact of the change on the project objectives, scope, schedule, cost, quality, risk, and stakeholder expectations. The project manager should then communicate the change and its implications to the appropriate stakeholders, such as the sponsor, customer, senior management, team members, etc., following the project escalation policy and communications management plan. The project escalation policy defines the process and criteria for escalating issues and decisions to higher levels of authority within the organization. The communications management plan describes how, when, and by whom information will be distributed, received, and stored throughout the project. By following these plans, the project manager can ensure that the change is properly reported, documented, approved, and implemented, and that the project stakeholders are kept informed and engaged.

The Stakeholder Engagement Assessment Matrix is a tool used to identify the current and desired levels of stakeholder engagement throughout a project. It helps project managers to monitor and compare the expected engagement and involvement of stakeholders against actual engagement. If a major stakeholder is unaware of recent developments, it suggests there may be a gap in the desired and actual engagement levels, which this matrix is designed to track and highlight.
: = The information is aligned with the PMBOK Guide, which outlines the importance of stakeholder engagement and the use of the Stakeholder Engagement Assessment Matrix as a tool to manage and assess this engagement12. Additionally, the PMI's standards for project management emphasize the need for effective communication and engagement with stakeholders to ensure project success34.

Team velocity is a measure of a team's effective productivity and capacity in agile development. It indicates the amount of work a team can accomplish in a given sprint, usually expressed in story points1. Team velocity can vary from sprint to sprint due to various factors, such as team size, complexity, dependencies, quality, and external interruptions2. Therefore, it is important for the project manager to monitor and review the team velocity over the last several sprints and use the average or trend as a basis for planning and forecasting future sprints3. By adjusting the plan according to the team velocity, the project manager can help the team avoid overcommitting or underdelivering, and set realistic and achievable sprint goals4.
The other options are not the best choices for the project manager in this situation. Switching to a Kanban approach (option A) may not solve the problem of sprint failures, as Kanban is a different agile framework that does not use fixed-length iterations or predefined roles. Kanban focuses on visualizing the workflow, limiting the work in progress, and optimizing the flow of value5. While Kanban can help the team improve efficiency and flexibility, it may not be suitable for every project or organization, and it may require a significant change in the team's culture and processes. Asking the project sponsor to approve overtime (option C) may not be a sustainable or effective solution, as it may lead to burnout, lower quality, higher costs, and reduced motivation among the team members6. Replacing junior team members with more experienced ones (option D) may not be feasible or desirable, as it may disrupt the team's dynamics, trust, and collaboration. It may also create resentment, conflict, and turnover among the team members. Negotiating the project scope to compensate for the budget gap may not be aligned with the project's objectives, stakeholders' expectations, or agile principles7.

In an agile project, the sprint review is the appropriate meeting for stakeholders, including board members, to attend. It is a formal opportunity to inspect the increment of the project's deliverables and adapt the product backlog if needed. The sprint review is designed to gather actionable feedback and foster collaboration between the development team and stakeholders12.
: = Agile practices in project management encourage stakeholder involvement in product backlog and project progress1. The PMI also highlights the importance of stakeholder engagement in agile projects, suggesting their participation in planning and review sessions2. Additionally, the importance of board member attendance in meetings is emphasized as it is essential for legal transaction of business and effective board engagement3.
