Fundamental design consideration for a net new CMDB
A Configuration Management Database (CMDB) is a powerful tool that helps organizations manage IT services and digital assets. However, many businesses have struggled with inaccurate or complex CMDB implementations, which can lead to costly outages and other issues. To avoid these problems, there are several fundamental design considerations to keep in mind when implementing a new CMDB.

First, it's important to carefully consider the scope of the CMDB. This includes deciding which types of configuration items (CIs) will be included and how much detail will be tracked for each CI. It's important to strike a balance between including enough information to be useful without overwhelming the system with unnecessary data.

The data model is also a key consideration. This refers to the way data is structured and related to each other within the CMDB. The data model should be designed to support the organization's business needs while also allowing for flexibility as the organization evolves. This can be accomplished through conceptual, logical, and physical data models.

CI class ownership is another important consideration. CI classes are groups of CI types that share the same attributes, and they should be carefully selected based on the needs of the organization. Only the necessary CI classes should be turned on in the production CMDB to avoid unnecessary complexity and maintainability issues.

Data quality is also crucial for a successful CMDB implementation. Organizations should establish clear data governance policies and procedures to ensure that data is accurate, complete, and up to date. This includes defining roles and responsibilities for data management and establishing clear processes for data validation and updates.

Finally, it's important to establish clear processes and procedures for CMDB maintenance and management. This includes defining roles and responsibilities, establishing clear change management processes, and regularly reviewing and updating the CMDB to ensure it remains accurate and useful.
