Which of the following is a key metric for evaluating project success?

Client satisfaction is a key metric for evaluating project success because it directly reflects the project's ability to meet the needs and expectations of the stakeholders involved, particularly the client. When clients are satisfied with the outcome, it indicates that the project objectives were achieved effectively, and resources were managed well to deliver value. This metric is often assessed through surveys, feedback sessions, and client testimonials, giving insight into areas of strength and opportunities for improvement.

In contrast, other options such as team size, office location, and the number of meetings held do not inherently reflect the project's success. Team size can impact efficiency and outcomes but does not directly measure the satisfaction level of clients. The office location may influence logistics and communication but is not a determinant of project success. Similarly, while the number of meetings can indicate communication frequency, it does not equate to successful project delivery or client satisfaction.
