In the context of remote work, especially when unforeseen risks require a shift to remote operations, it is crucial for project managers to adapt their communication and resource management strategies. This ensures that all team members, including outsourced vendors, are aligned and can deliver effectively. Developing a new strategy may involve leveraging technology for virtual meetings, establishing clear communication protocols, and ensuring that all team members have access to necessary resources and information to perform their tasks remotely1.

In a situation where a project manager is asked to provide cost estimates for a new decoration project within a short time frame, the best approach would be to contact a subject matter expert (SME) for advice and consultation12. This is because SMEs have the necessary expertise and experience to provide accurate and reliable cost estimates quickly12. They can provide insights into the costs of materials, labor, and other factors that are crucial for the project12. This approach ensures that the cost estimates are as accurate as possible, which is crucial for the success of the project12.

A project manager who is managing two integrated projects in a program should use effective communication and conflict management skills to resolve issues that arise from misalignment or integration points. The project manager should first meet with both integration leads to understand the root cause of the problem and facilitate a collaborative solution that satisfies both parties and aligns with the program objectives. Assigning the resolution of the issue to either one of the integration leads, or escalating the issue to the program architect, are not the best options as they may create more conflict or undermine the authority of the project manager.
