When a project experiences a delay, it's crucial to reassess the project plan and identify options to meet stakeholders' expectations. This involves revisiting the scope and quality of the project. The project manager should explore all possible options to deliver the project within the constraints. This could involve adjusting the project schedule, reallocating resources, or identifying efficiencies in the project processes. It's important to communicate these changes and their potential impact to all stakeholders. References: PMBOK Guide, 6th Edition, Section 6.7 Control Schedule
