What is a good practice when someone asks you a question you cannot answer?

When faced with a question that you cannot answer, directing the individual to your boss is a good practice because it demonstrates professionalism and accountability. This approach allows you to remain transparent about your limitations while ensuring that the person’s inquiry is addressed by someone who may have the necessary information or expertise. This route not only maintains the credibility of your response but also shows respect for the person asking the question, as it indicates that their query is valued and should be answered properly.

In contrast, making something up can lead to misinformation and could harm both your own credibility and the organization’s reputation. Changing the subject can come across as dismissive and may frustrate the individual seeking an answer. Dismissing the inquiry outright fails to acknowledge the speaker's needs and can damage relationships, suggesting a lack of concern for their questions or concerns. Therefore, referring the question to a superior is the most constructive and responsible choice.
