The project manager's role includes managing day-to-day operations and ensuring the project is completed on time, on budget, and achieves its objectives1. When unexpected changes occur, such as the need for team members to work remotely and incur operational expenditures, it's important to follow the Perform Integrated Change Control process. This process involves reviewing all requested changes, approving changes, and managing changes to deliverables, organizational process assets, project documents, and the project management plan2. In this case, the project manager should submit a change request to address the additional costs incurred by the team members. This ensures that the project's budget and schedule are updated accordingly and that the project continues to align with its objectives.
