In today's global and hybrid working environments, virtual meetings are a standard method for maintaining productivity when physical presence isn't possible. The PMBOK Guide - Seventh Edition emphasizes the use of collaborative tools and techniques, especially in distributed or constrained environments.
Option A reflects a pragmatic and proactive approach, ensuring continuity without delay. It also supports agile principles of adaptability and responsiveness to change.

The performance rating of project team members should primarily reference the agreed-upon key performance indicators (KPIs). KPIs are quantifiable measures that are established at the beginning of the project to evaluate the success of the project and the contribution of team members towards achieving project objectives. This approach ensures that the assessment is objective and based on predefined criteria, rather than subjective opinions or inputs.
: = The importance of using KPIs for performance assessments is supported by project management and business analysis standards, which advocate for measurable and objective criteria in evaluating team performance12.

Net Present Value (NPV) is the most appropriate financial metric for comparing long-term project investments such as build vs. buy options. It helps assess which option provides greater value over time after considering costs and future benefits discounted to present value.
PMI recommends NPV as a key tool in investment decision-making during project selection and early planning stages.
EMV is best used in risk-based decision-making.
EV measures performance during execution.
Impact value is not a recognized PMI metric.

The Project Management Professional (PMP) certification emphasizes the importance of human resource management and the development of the project team. According to the PMBOK Guide, project managers should develop the team through training, team-building activities, and creating an environment that promotes high performance. In the scenario provided, where the team lacks experience, the project manager should utilize coaching and mentoring to bridge the experience gap, enhance skills, and improve team performance. This aligns with the PMP's focus on leadership and the development of human resources within the project team.
The references for this answer are drawn from the PMBOK Guide and the PMP Examination Content Outline, which detail the project manager's role in team development and the competencies required for effective project management. Additionally, the Professional in Business Analysis (PMI-PBA) reference materials support the approach of enhancing competencies through coaching and mentoring to ensure project success.

In a situation where a developer is delaying a critical path activity due to a lack of understanding of customer requirements, the project manager should facilitate communication to ensure clarification of the requirements. This approach aligns with the best practices in project management and business analysis, which emphasize the importance of clear communication and understanding of stakeholder requirements for project success. By clarifying the requirements, the developer can gain a better understanding of what is expected and proceed with the coding activity, thus mitigating the delay on the critical path.

PMI's Guide to the Project Management Body of Knowledge (PMBOK Guide) emphasizes the importance of stakeholder engagement and effective communication to ensure that project requirements are understood and met1.
The PMI Professional in Business Analysis (PMI-PBA) highlights the role of communication in business analysis, including the need for clarity and the avoidance of misunderstandings23.
Discussions among PMP professionals also suggest that once a root cause analysis is performed and the issue is identified, the next step is to address the issue directly, which in this case involves clarifying the requirements1.
