Which of the following is a key benefit of using a stakeholder matrix?

A stakeholder matrix is a valuable tool that assists in the analysis and management of stakeholders' influence and interest in a project. By categorizing stakeholders based on their level of influence and interest, it allows project managers and business analysts to identify which stakeholders to engage with most actively. This prioritization is crucial because it ensures that the voices of the most influential stakeholders are heard and considered, which is essential for project success.

By focusing on the key stakeholders who have the most significant impact or interest, a stakeholder matrix helps in formulating strategies for engagement that resonate with their needs and expectations. This facilitates a more effective management of relationships, fosters collaboration, and ultimately leads to better project outcomes.

While the other options touch on important aspects of project management, they do not capture the primary role of a stakeholder matrix as effectively as prioritizing stakeholder engagement does. For instance, streamlining communication, managing risks, and facilitating requirement gathering are outcomes that may be influenced by strong stakeholder engagement but are not the primary focus of the stakeholder matrix itself.
