Who can be defined as an individual or group that has an interest in the outcome of a project?

The correct choice is that a stakeholder is defined as an individual or group that has an interest in the outcome of a project. Stakeholders can include anyone who is affected by or has an influence on the project, ranging from team members and clients to sponsors and even the community. Their interests can vary, including financial, emotional, or strategic aspects related to the project.

Understanding the role of stakeholders is crucial in project management as they can significantly impact the direction and success of a project. Engaging stakeholders early and often throughout the project lifecycle can lead to more favorable outcomes and improved satisfaction with the results, as their needs and concerns are taken into account.

The other roles mentioned, such as the project manager and executive sponsor, are specific positions with distinct responsibilities. While they certainly have a vested interest in the project's success, the term "stakeholder" encompasses a broader range of people and groups with potential interest in or influence over the project. Team members also have a stake, but they are just one type of stakeholder among many others.
