The next person needs to know which files to use, what still needs doing and who to ask. Give them enough context to get started.
You can hand over every file and still leave the next person wondering where to start. Explain what’s happening, who’s responsible and which questions you haven’t answered yet.
Separate current work from old examples. Point out the latest version of each important document and explain what it’s for. Label anything that’s out of date so the next person doesn’t have to work it out.
List unfinished tasks, who’s responsible and the deadlines or check-ins that matter. Say what needs to happen next. Label ideas that haven’t been agreed on so they don’t get mistaken for promises.
List the systems and accounts the role needs, then follow your organization’s process for transferring access. Don’t put passwords or private information in a general handover document.
Share one or two things that worked, a problem to watch for and a question worth asking. Stick to what you observed, and label any assumptions about people.
Ask the next person what they’d do first. Their questions can show you what’s missing while you’re still there to explain it. They should leave knowing how to get started.
