When a regulatory authority announces changes that affect a project, it is essential for the project manager to review these new requirements with the compliance department. This is to understand the implications of the changes and to determine if a change request is necessary. The project manager must ensure that the project remains compliant with all relevant regulations, and this often requires adapting the project scope and plan to accommodate new regulatory requirements. Ignoring such changes or delaying their implementation could result in non-compliance and potential legal and financial repercussions for the project.
