When faced with dissatisfaction from a stakeholder, it is important for the project manager to listen actively and demonstrate empathy. This approach aligns with the PMBOKGuide's emphasis on effective communication and stakeholder engagement as key aspects of project management. By listening carefully, the project manager can understand the concerns and needs of the functional manager, which is crucial for maintaining a positive relationship and ensuring project success. Additionally, this strategy is supported by conflict resolution techniques that prioritize collaboration and problem-solving, as outlined in PMI's resources on managing project conflicts12.
