In today's fast-paced technological landscape, efficient IT asset management is crucial for maintaining smooth business operations. The Configuration Management Database (CMDB) in ServiceNow serves as a foundational element for organizing and tracking IT assets, configurations, and relationships. However, to keep the CMDB accurate and effective, regular cleansing and maintenance are imperative. In this article, we'll explore actionable steps to cleanse and maintain your ServiceNow CMDB effectively.
The CMDB is the heart of IT service management, containing essential data about IT assets, configurations, and their interdependencies.
