PMP Practice: Update Documentation for Changes

Ziggy Okonkwo-Petersen is managing a warehouse automation project for Barakah Biotech using a predictive approach. During execution, the operations director submits an urgent request to add real-time temperature monitoring for pharmaceutical storage—a capability not in the original scope. The operations director insists this feature is critical for a new client contract worth $8M annually and claims the CEO verbally approved it last week. Ziggy checks the project charter and scope baseline, which do not include this functionality. The change would require an additional 6 weeks and $240K. The project is currently on schedule and within budget, but the team is fully allocated. What should Ziggy do FIRST?
