COMPUTERIZED MAINTENANCE
MANAGEMENT SYSTEM(CMMS)
 A CMMS software package maintains
a computer database of information
about an organization’s maintenance
operations.
 This information is intended to help
maintenance workers do their jobs
more effective.

Benefits
 Achieving high efficiency.
 Minimizing usage of parts and labor.
 Maximizing usage of equipments and
minimizing downtime.
 Maximizing equipments lifetime and
replacement period.
 Minimizing maintenance and operation
costs.
 Maximizing profits.
 Raising performance levels.
 Allows the safe and efficient functioning.

The CMMS enables management to:
 Schedule preventive and predictive
maintenance procedures, and parts and
labor utilization for maintenance tasks.
 Project and monitor downtime and causes.
 Project and monitor costs, repairs, and
usage of spare parts and labor.
 Analyze failures, costs, maintenance
procedures, and resource usage.

CMMS- Computerized Maintenance Management System
ERP –Enterprise Resource Planning
EAM -Enterprise Asset Management

ERP or CMMS –
fundamental differences
 ERP
 ERP systems are built
around accounting.
 ERP systems often
takes fixed asset
module in accounting
as starting point.
 Covering basic
maintenance
functionality.
 CMMS
 CMMS systems are
developed with the
maintenance processes
in focus.
 Deeper functionality
for maintenance
specific tasks.
