How often should knowledge articles be reviewed in KCS?

Knowledge articles in Knowledge-Centered Service (KCS) should be reviewed regularly, based on their usage and relevance. This practice helps ensure that the knowledge base remains accurate, up-to-date, and aligned with the current needs of users. Regular reviews allow teams to identify articles that may require updates due to changes in products, services, or processes, as well as articles that are no longer relevant.

By focusing on the actual usage of knowledge articles, this approach prioritizes the most frequently accessed content and ensures that valuable information is clearly communicated and maintained. In contrast, the other options suggest infrequent or situational reviews that could lead to outdated or irrelevant information being circulated, ultimately undermining the effectiveness of the knowledge management process.
