A multimillion-dollar project in execution received notice of regulatory requirement changes that must be implemented in six months, before project completion. What should the project manager do next?

The project manager's first step should be to review the new requirements with the compliance department. This collaborative approach ensures a thorough understanding of the regulatory changes, their impact, and whether they necessitate a formal change request. It allows for proper assessment before committing to any action. Proceeding with original requirements is incorrect because regulatory changes are mandatory and cannot be ignored or delayed without significant risk. Adding the requirements immediately is premature; a proper impact analysis and change control process are required for such a significant change. Ignoring the requirements is unacceptable and would lead to non-compliance and potential legal or financial penalties for the organization.
