Computerized Maintenance Management System (CMMS) is also known as Computerized Maintenance Management Information System (CMMIS) is a software package that maintains a computer database of information about an organization's maintenance operations.

• This information is intended to help maintenance workers do their jobs more effectively. For example, determining which machines require maintenance and which storerooms contain the spare parts they need.
• CMMS data may also be used to verify regulatory compliance.
• CMMS packages may be used by any organization that must perform maintenance on equipment, assets and property.
