Step-by-Step Workflow

Specific, executable steps you can start today.

1

Audit knowledge that lives in people's heads

Interview 5–10 employees: "What do you wish you had documentation for when you started?" and "What questions do you get asked most often?" This becomes your KB backlog.

2

Set up your Notion structure

Create top-level sections: Company Handbook, Engineering, Sales, Marketing, Operations, Product. Under each: Getting Started, Processes, Tools & Access, FAQs. Keep it shallow — max 3 levels deep.

3

Draft docs using ChatGPT from interviews

Record 30-minute "knowledge extraction" calls with subject matter experts. Transcribe with Otter.ai. Paste transcripts into ChatGPT: "Turn this conversation into a clear, structured how-to document with: overview, steps, examples, and gotchas."

4

Use Notion AI for maintenance

Turn on Notion AI for all editors. When a process changes, employees update the relevant page. Use Notion AI to rewrite unclear sections, translate to other languages, or generate a summary at the top.

5

Connect to Slack with Notion + Slack integration

Enable the Notion-Slack integration. Employees can type /notion search [query] directly in Slack and get relevant KB page links. Reduces the "where is this documented?" interruption cycle.

6

Build a maintenance ritual

Add "Is this still accurate?" to every document as a monthly calendar reminder. Assign each section to a "documentation owner." Outdated docs are worse than no docs — enforce a quarterly review cycle.

Expected Outcome

60% fewer repetitive Slack questions, 40% faster new hire onboarding

What Can Go Wrong

Common failure points teams hit when implementing this workflow.

Documentation that no one uses. The #1 reason: hard to find and no one knows it exists. Announce every new document in the relevant Slack channel when published.

Stale documentation is dangerous — it creates confident wrong answers. Set expiry dates on every process doc and remove pages that are more than 1 year old without review.

Too much structure too early. Starting with a perfectly organized hierarchy before content exists means no one fills it in. Start messy, organize after you have 50+ documents.
