When faced with a potential delay due to a vendor’s resource shortage, the project manager should engage the project team to explore alternative options to adhere to the schedule. This aligns with the principles of project management, which emphasize proactive problem-solving and collaboration to maintain project momentum. The PMBOK® Guide highlights the importance of communication and stakeholder engagement in managing project risks, including those associated with vendor deliverables. By discussing alternative options, the project manager can facilitate a solution-oriented approach that may involve re-allocating resources, adjusting work priorities, or finding other ways to mitigate the delay without compromising the project’s objectives or quality standards.
