Which statement does NOT measure a project's success?

Reducing high-probability risks is an important aspect of project management and contributes to the overall health of a project, but it does not directly measure the success of the project itself. Project success is typically evaluated based on outcomes such as stakeholder satisfaction, achievement of project objectives, and efficient resource utilization.

High satisfaction scores from stakeholders indicate that the project has met or exceeded their expectations, which is a clear measure of success. Increased community impacts reflect positive outcomes resulting from the project, showcasing its effects beyond just the immediate goals. Effective use of time and resources ensures that the project is delivered within its parameters, which is another vital measure of success.

While managing risks is crucial to avoiding problems during the project lifecycle, simply reducing risks does not quantify whether the project has achieved its goals or delivered value, which are the primary determinants of project success. Thus, this choice is distinct from the others, as it focuses on a process associated with project management rather than on outcomes that define success.
