Discussion: Best practices for managing a knowledge base?

As our company grows, our knowledge base is becoming increasingly difficult to manage. We have a lot of outdated articles, and it's becoming a challenge to ensure that our customers and agents are finding the most accurate and up-to-date information. I'm curious to hear how other companies are tackling this challenge. What are your best practices for knowledge base management? How do you decide when to update or retire an article? What tools or processes do you use to keep your content fresh and relevant? I'm open to any and all suggestions, as we are looking to completely overhaul our knowledge base strategy in the coming months.
