How do I capture knowledge before an experienced coworker becomes unavailable?
Quick answer
Start with the work that would be hardest to pause or hand over, then ask your coworker if they are willing to explain how they do it. Capture the steps, decision points, exceptions, and where to find current information. Check your notes with them, mark anything uncertain, and agree who can maintain the guide. Keep the request focused and respectful; do not assume why or when they may become unavailable.
The question, the details, the next step.
A practical checklist
Choose one recurring or difficult-to-cover task and agree it is a useful priority.
Ask permission and explain the practical purpose without asking about personal circumstances.
Capture triggers, inputs, steps, decision points, exceptions, and completion checks.
Mark uncertain details as open questions rather than inventing instructions.
Review the draft with the coworker and agree who can update it.
A few more useful answers
Should I try to document every task the coworker handles?
Usually start with a small number of high-priority tasks rather than attempting an exhaustive record. Ask the coworker which work would be most useful to make easier to cover.
What if my coworker does not want to share or document their process?
Respect their choice and ask whether there is a smaller topic or different format they would be comfortable with. You can also ask an appropriate manager or process owner what existing guidance is available, without presenting unconfirmed details as fact.
How do I keep the notes from becoming outdated?
Name a role or person to review them, and make unresolved questions and the last review date visible. When the process changes, update the affected steps rather than assuming the old guide still applies.
