Let's say you are managing a project for designing and building a 10,000 square foot medical building. After performing all appropriate activities, the scope is agreed to and documented. The building will hold three specialty clinics (Allergy Clinic, Dermatology Clinic, and Pulmonary Clinic), each having one waiting room, one doctor's office, and four exam rooms. Afterthe project reaches 50%, the customer now wants to add a fourth clinic (Eye Clinic). Would this incorporation suffice since the project is 50% complete or would additional planning processes be needed? Explain using a research article.
