Figure 9-1 details the four main reasons for computerizing maintenance management.
GOALS FOR COMPUTERIZATION
Provide Vehicle for Enforcing Maintenance Disciplines
Provide Faster, More Accurate Record Keeping Capabilities
Provide "Snapshot" Analysis of Maintenance Information
Provide a Method of Integrating Maintenance with Other Information Systems

Every CMMS, whether purchased from a vendor or developed in house, has its own philosophy of how maintenance should operate. This philosophy governs how information is collected on a work order, stores and purchasing procedures, reports, and many other areas. The structure and philosophy of the CMMS will also determine how your company manages maintenance. Selecting the right CMMS, therefore, is very important.
