Which term reflects the ability to be counted on to follow through on commitments?

Reliability is the term that best captures the ability to be counted on to follow through on commitments. When someone is reliable, it means they consistently meet their obligations and deliver on promises, which fosters trust and dependability in both personal and professional relationships. This characteristic is essential in various contexts, such as teamwork, project management, and customer service, where individuals or teams need to perform consistently to achieve their goals.

In contrast, ambition refers to a strong desire to achieve success, which does not necessarily imply follow-through on commitments. Enthusiasm reflects a passionate and positive attitude towards tasks or activities but lacks the connotation of dependability. Creativity involves the ability to think outside the box and generate innovative ideas, which, while valuable, does not address the concept of consistency in fulfilling responsibilities. Thus, reliability stands out as the most fitting term associated with the ability to keep commitments.
