The project manager must take immediate action to address both behavioral and performance issues.
Providing direct, constructive feedback to the underperforming senior technical member will help address their critical behavior and performance lapses. According to the PMBOK Guide - Seventh Edition, project managers are responsible for managing interpersonal conflicts and promoting team collaboration.
By addressing the disruptive behavior and lack of task performance, the project manager fosters a psychologically safe environment and restores team dynamics.
Option A avoids the issue and reduces collaboration.
Option B escalates prematurely and may cause greater disruption.

The best course of action when receiving a request for a more detailed project status is to engage in a dialogue with the senior manager to understand their specific needs. This approach aligns with the PMBOK Guide's emphasis on effective communication and stakeholder engagement as key aspects of project management. By discussing the requirements directly, the project manager can tailor the communication to provide relevant and precise information that satisfies the senior manager's request without overwhelming them with unnecessary details. This method ensures that the project manager is responsive to stakeholder needs and maintains clear and open lines of communication.
: The answer is supported by the principles outlined in the PMBOK Guide, which advocate for proactive stakeholder engagement and effective communication strategies1. Additionally, the PMI's standards on project communication emphasize the importance of understanding and addressing stakeholder information needs23.

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.
