Final answer:
The description that best represents goal-setting theory is that managers can increase motivation and improve performance by setting specific, challenging goals and offering timely feedback.
Step-by-step explanation:
The correct answer to the question "Which of the following descriptions best indicates what goal-setting theory is about?" is managers increase motivation and enhance performance by setting specific, challenging targets and providing timely feedback.
Goal-setting theory, as put forward by Edwin A. Locke in the late 1960s, suggests that clear and challenging goals can improve employee performance. This is because specific and difficult goals give employees a clear idea of what is expected and push them to achieve at a higher level than they might with easy or ambiguous goals. Moreover, goal-setting is usually more effective when there is timely feedback, allowing individuals to track their progress, adjust their strategies, and stay motivated. This theory is supported by a wealth of psychological research, which shows that precise goals that push individuals just beyond their comfort zones are most likely to lead to higher levels of performance.
