Before communicating with the client about a potential delay, it is crucial for the project manager to work with the project team to evaluate the delay. This involves analyzing the situation, understanding the causes, and exploring possible solutions or adjustments to the project plan. The project manager should gather all necessary information to provide a clear and factual update to the client, including any changes to the project timeline, scope, or costs. This approach aligns with best practices in project management, which emphasize the importance of internal assessment and problem-solving before external communication.
