4.3Documentation Strategies

Written Documentation

Format	Best For	Strengths	Weaknesses
Wiki pages (Confluence, Notion)	Process docs, how-tos, reference material	Searchable, easy to update, collaborative	Can become outdated without maintenance
Runbooks	Step-by-step procedures for specific tasks	Precise, actionable, reduces errors	Brittle if systems change frequently
Architecture decision records (ADRs)	Documenting why decisions were made	Preserves context and rationale	Requires discipline to write at decision time
README files in repos	Setup instructions, test running guides	Co-located with code, version controlled	Limited to developer audience
Annotated test suites	Test intent, domain rules, edge case rationale	Lives with the tests, always current	Only accessible to people who read test code

Video Walkthroughs

Video is underused in QA teams but is one of the most effective knowledge transfer tools.

When to use video:

• Explaining complex test scenarios that are hard to describe in text
• Demonstrating debugging techniques or tool usage
• Walking through the product's user flows and common issues
• Recording "a day in the life" of testing a specific feature

How to make effective videos:

• Keep them under 15 minutes (5-10 is ideal)
• Narrate your thought process, not just your actions
• Use screen recording with your face visible (builds connection)
• Store them in a shared, searchable location with timestamps and titles
• Accept imperfection -- a quick, rough video recorded today is infinitely more valuable than a polished video never recorded

Tools: Loom, OBS Studio (free), QuickTime (macOS), built-in screen recording on most operating systems.
