6.9Hands-On Exercise

1. Audit your current QA knowledge base. Create an inventory of what exists, what is outdated, and what is missing.
2. Write one runbook for a QA task that currently lives only in someone's head (environment setup, test data refresh, or deployment verification).
3. Create a troubleshooting guide for the most common issue your QA team encounters.
4. Write a decision log for the most recent significant technical decision your team made.
5. Implement a quarterly documentation review process: assign owners, set review dates, and create a tracking mechanism.

Interview Talking Point: "I treat documentation as a first-class engineering deliverable, not an afterthought. On my teams, I have established docs-as-code practices where test documentation lives in the repository alongside the tests, goes through PR review, and is validated by CI -- including link checking and format linting. I build QA knowledge bases structured around tasks rather than document types, with runbooks for common procedures, troubleshooting guides for known issues, and decision logs that capture why we made certain testing choices. I assign ownership to every document and run quarterly freshness reviews, because outdated documentation is worse than no documentation. When team members leave, I conduct structured knowledge extraction sessions to capture domain knowledge before it walks out the door. The result is a team that onboards new engineers in days instead of weeks, avoids repeating past mistakes, and maintains institutional knowledge regardless of personnel changes."
