The term "poor performance" refers to a lackluster or subpar showing in an activity, task, or role. It can indicate that someone is not meeting expectations, whether it be due to a lack of effort, skill, knowledge, or resources. Poor performance may result from various factors such as stress, fatigue, lack of motivation, or insufficient training. In general, poor performance suggests that there is room for improvement and can lead to consequences such as negative feedback, loss of opportunities, or disciplinary action.
