The document describes a computerized maintenance management system (CMMS) and its functions. A CMMS maintains a database of information about an organization's maintenance operations to help workers perform their jobs more effectively. It enables management to schedule preventive maintenance, project costs and downtime, and analyze failures and resource usage. The CMMS has several key functional requirements including asset management, inventory management, work orders, job planning, resource planning, and reporting. It helps organizations achieve greater efficiency, minimize costs and downtime, and maximize asset usage.

2. 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.

3. 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.

4. 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.

7. 1. Asset Management & Asset
Register Function
 Location details of equipments and
it’s hierarchy.
 Building spare parts and sub-assembly
catalogues .
 Links to inventory management and
purchase functions.

8. 2. Inventory Management Function
 Tracking of stocked and non-stocked
items through multiple stores.
 Tracking of items, costs and balances
by bin, lot and storeroom.
 Stock replenishment when inventory
falls below minimum levels
 ABC and XYZ analysis .

9. 3. Work Order Function
 Viewing comprehensive and detailed planning
information such as
 • Work Plans
 • Target and scheduled date
 • Costs
 • Labour, materials, Skill set / crafts,
 • Failure analysis
 Predictive maintenance.
 Scheduling of work orders based on real time
criticality and logistics.

10. 4. Job Planning Function
 Tracking of costs by operation or job
plan.
 Linking job plans sequentially, each
with it’s own parts, labour and tool
estimates.

11. 5. Resource Planning Function
 Resource function shall allow to
maintain detailed resource
information to plan and analyze
maintenance work related to
company, service contract, tools etc.

12. 6. Schedule Planning Function
 Scheduling function shall enable to
forecast future preventive
maintenance dates for resource
planning.

13. 7. Maintenance Management
 Allows each asset / equipment to
have a defined maintenance profile
 Helps to schedule planned preventive
and predictive maintenance routines.
 Control maintenance procedures.

15. 8. Purchasing Function
 Creation of purchase requisitions or
purchase orders either from scratch or
from the inventory or work order
modules.
 Analyzing of vendor performance before
ordering of part.
 Auto re-orders generation for the
spares, when stock falls below re-order
level.

16. 9. Reporting Functions
 Standard Reports-Generation of
standard reports on work orders,
safety plans, inventory values and
other critical points about
maintenance operations.
 Report types- Capabilities shall
include columnar reports, forms, Bar
Charts, Pie Charts, Cross tabs etc.

EAM -Enterprise Asset Management

18. 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.
