What term is used to describe individuals or groups affected by a change and have the ability to influence that change?

The correct term that describes individuals or groups affected by a change and who have the ability to influence that change is "stakeholders." Stakeholders encompass a wide range of entities, including employees, customers, suppliers, investors, and community members who have a vested interest in the outcome of a project or initiative. Their influence and interest can significantly impact the success of a change, as they may provide valuable insights, support, or resistance based on how the change affects them.

Understanding stakeholders is critical in business analysis because their needs and concerns must be identified and addressed to facilitate successful change management. This engagement can lead to better decision-making, enhanced collaboration, and ultimately, a more effective implementation of strategies to achieve the desired outcomes.

In comparison, the other terms provided may refer to specific groups or perspectives within the broader stakeholder community, but they do not fully encompass the wide-ranging influence and effect of all stakeholders involved in a change initiative. For instance, a partner or investor may play important roles, but a stakeholder perspective is much broader, including anyone who might be impacted by or who could impact the change process. Thus, "stakeholders" is the most comprehensive and correct choice in this context.
