A knowledge base is a centralized documentation repository that includes frequently asked questions, how-to guides, and troubleshooting instructions. Its goal is to make it simple for people to solve difficulties without asking for assistance. Knowledge bases result from a process known as "knowledge management" that collects and organizes all of that data in a meaningful manner. External or internal audiences can both benefit from knowledge bases. An appliance manufacturer, for example, might keep maintenance instructions in a customer-facing knowledge base and an internal knowledge base where personnel can learn about company policies.
