Product documentation strategy and maintenance

Create and maintain comprehensive product documentation ecosystem. Documentation types: 1. User guides: step-by-step instructions for end users. 2. API documentation: endpoints, parameters, examples. 3. Admin documentation: configuration, troubleshooting. 4. Developer docs: SDKs, integration guides. 5. Release notes: feature updates, bug fixes. Content strategy: 1. Audience-based: different docs for different user types. 2. Progressive disclosure: basic → advanced information. 3. Multimedia: screenshots, videos, interactive tutorials. 4. Search optimization: logical structure, good navigation. Maintenance workflow: 1. Documentation requirements in user stories. 2. Review process: technical accuracy, clarity. 3. Version control: docs synchronized with product releases. 4. Analytics: track usage, identify gaps. 5. User feedback: ratings, comments, improvement suggestions. Tools: GitBook, Notion, Confluence for authoring, Algolia for search. Success metrics: documentation usage, support ticket reduction, user satisfaction scores. Keep docs current: assign ownership, regular audits, automated link checking.
