Explanation
According to the PMBOK Guide, the project manager should monitor and control the project work, including identifying and responding to risks, issues, and changes that may affect the project objectives. The project manager should also communicate relevant information to the project stakeholders in a timely and appropriate manner. In this scenario, the project manager faces a resource risk that may impact the project deliverable and schedule. The best course of action is to perform an impact analysis to assess the severity and probability of the risk, and then readjust the schedule as needed to accommodate the resource gap. The project manager should also communicate the changes to the customer and other stakeholders, and seek their feedback and approval. This option demonstrates proactive and transparent project management, and aligns with the agile values of customer collaboration and responding to change. Asking the product owner to stretch the delivery team further to complete the final product in the original timeline (option B) may not be feasible or desirable, as it may compromise the quality and scope of the product, and increase the stress and workload of the team.
Requesting additional funding from the sponsor to obtain a new resource to fill in the gap (option C) may also be unrealistic or unnecessary, as it may incur additional costs and time to onboard and train the new resource, and may disrupt the existing team dynamics and performance. Informing the customer of the impact immediately and preparing for escalation (option D) may also be premature and counterproductive, as it may create unnecessary panic and conflict, and may undermine the trust and confidence of the customer and other stakeholders. The project manager should first analyze the impact and propose a solution before informing the customer and escalating the issue. References: : Project Management Institute. (2017).
