When external business influences cause changes in business parameters, the project manager should request an update of the project requirements to reflect these changes. This ensures that the project remains aligned with current business objectives and can deliver value as intended. It is a proactive approach that allows for the project to adapt to changing circumstances, which is a key aspect of effective project management. The PMBOK Guide emphasizes the importance of continuously monitoring and controlling project work to ensure that project objectives are met and that project work aligns with the business needs2.

In project management, it's crucial to engage all stakeholders and ensure their feedback is considered. When a stakeholder is not providing feedback, it's important to understand the reason behind their reluctance.
Scheduling a one-on-one meeting can provide an opportunity for the project manager to address any concerns or issues the stakeholder may have, which might be preventing them from providing feedback. This approach is aligned with the PMBOKGuide's emphasis on stakeholder engagement and communication management.
