A Capacity Management Information System or CMIS is a collection of IT infrastructure usage, capacity and performance information that has been gathered in a consistent manner and stored in one or more databases. It is the single book of record for all usage, capacity, and performance data, complete with associated business, application and service statistics. Any IT staffer needing access to capacity management data can potentially use a CMIS.

IT service management processes frequently accessing CMIS data are:

• Capacity planning
• Performance management
• Service level management
• Help/Service desk
• Incident management

• Problem management

• Configuration management
