Response: In such a scenario, it's important to approach the situation with transparency and effective communication. First, I would assess the impact of the unforeseen issues on the project timeline, budget, and overall objectives. Then, I would convene a meeting with key stakeholders to discuss the necessary changes to the scope. 

During this meeting, I would present my findings and recommendations, ensuring that everyone understands the rationale behind the proposed changes. It's crucial to collaboratively decide on the best way forward, whether that involves adjusting timelines, reallocating resources, or redefining project goals. By maintaining open lines of communication and involving stakeholders in the decision-making process, we can navigate the changes effectively while minimizing disruption to the project.
