CMDB: why IT data quality matters

An operational source of truth

A CMDB connects applications, servers, contracts, dependencies and responsibilities. It helps understand the impact of an incident or a change before acting.

Common mistakes

• Building a CMDB that is too ambitious from day one.
• Not assigning ownership for data quality.
• Forgetting update processes.
• Not connecting the CMDB to incidents, changes and critical assets.

The right approach

Start with critical services, keep only useful attributes, then gradually integrate processes. Quality matters more than volume.
