If a change request is submitted that affects several other projects, who should approve it if it is deemed a positive addition?

The correct choice is that the organization's executive board should approve the change request when it affects several other projects and is deemed a positive addition. This scenario reflects the broader impact such a change might have, necessitating a higher level of authority for approval.

When a change has implications beyond a single project, it is essential to ensure that it aligns with the strategic objectives of the organization and does not adversely affect other initiatives. The executive board typically holds a comprehensive perspective on organizational priorities and resource allocation, making them well-suited to assess the overall implications of inter-project changes. They can evaluate not just the benefits and risks associated with the change but can also consider how it fits into the larger picture of the organization's goals and the potential impacts on all affected projects.

In contrast, project managers and core teams tend to focus on the execution and management of their specific projects. They may not have the authority or the full context to make decisions that affect multiple projects or the organization as a whole. Similarly, the project sponsor, while influential within a single project, may not be in a position to consider the overarching organizational effects of changes impacting several initiatives. Thus, the approval from the executive board ensures that there is a holistic approach to managing changes that cross project boundaries.
