What are good ChatGPT use cases that you successfully used to educate your department heads?

I'm looking for smaller examples that I could use to show the department heads and group leaders that would save them time if they tried them themselves next week. In my case the audience is non-technical but scientifically trained.

Have you had any use cases that were popular or could drive home the point how transformational the use of LLMs within a department could be?

Thanks in advance!
