Start with the tasks you perform each week. Identify which are repetitive and easy to check, and which need confidential data, professional judgment or approval.
Pick one small task to test
Try generating a meeting agenda from a fictional brief. Compare the result to your usual process for accuracy, omissions and editing time. Check every claim before reusing it.
Build a habit of verification
Use approved tools, protect sensitive data and document the steps that consistently save time. Keep developing domain knowledge so you can catch a plausible but incorrect output.
