What is a knowledge base and how should it be used?

• A. A centralized, approved repository of information used to answer inquiries; cite sources and keep it updated.
• B. A casual collection of informal notes.
• C. An external vendor's public encyclopedia.
• D. A monthly newsletter.

Answer: (A)

A knowledge base is a centralized, approved repository of information used to answer inquiries. It serves as the single source of truth where verified articles, how-to guides, and policies live, with citations and content kept up to date. Using it means you can quickly find accurate, consistent answers, enabling self-service for customers and faster, more reliable responses from staff. Articles are typically organized by topic and include tags and version history so you can trust you’re providing current guidance. The other options miss this combination of governance and permanence: informal notes aren’t controlled or updated; an external vendor’s public encyclopedia isn’t owned or maintained by your organization; a monthly newsletter isn’t designed to be a searchable, issue-focused resource.
