HR knowledge management is the practice of centralizing all HR documents, policies, information, and knowledge and making that vital information easy for anyone in the company to access and update from anywhere.
The key to this central repository is that it allows employees—regardless of department, location, or tenure—to quickly access the HR information they need via a 24/7 self-service portal. This reduces frustration for employees, the chance of getting outdated or misinformation, and workload for HR staff (who no longer have to answer the same question over and over again).
