Productive Maintenance
The traditional management concept considers equipment
maintenance unavoidable. This system is characterized by
run-to-failure breakdowns and is called corrective or
18
reactive maintenance. It strives to reduce the severity of
equipment failures once they occur. This tactic attempts
to restore equipment productivity in the least possible
time. These companies tend to retain standby machines,
large spare parts inventories, and use worker reassignments during breakdowns (Sheu, 1994).
Progressive companies, on the other hand, have come to
embrace preventative maintenance or PM systems, which
strive to reduce the frequency of failures once they occur.
They seek to build a system that finds potential failures
and seeks remediation to prevent these failures. This
technique uses a structured, procedural approach and sets
up formal guidelines and time schedules for maintenance
tasks (Sheu, 1994).
Increasingly, in the past decade, world-class
organizations have come to realize maintenance is not an
independent corporate entity that makes repairs as needed.
They have come to consider maintenance as a strategic
partner in striving to achieve a company’s corporate goals
(Fredendall, 1997). These companies consider proactive
maintenance techniques a tool to gain competitive
advantage. One particularly effective proactive
maintenance technique, called Total Productive Maintenance
or TPM, and was developed in Japan about 30 years ago.

Components of Productive Maintenance
TPM or Productive Maintenance requires corporate
management and employee involvement in a unified effort to
recognize equipment deficiencies. It substantiates that
successful industrial maintenance programs rely heavily on
root cause analysis and measurement of results (Hartmann,
1992). Beyond the need for management’s, acknowledgement
and commitment, successful productive maintenance programs
contain several other components closely resembling the key
elements of Risk Control as follows:
1. Develop the data needed to make decisions and set
priorities, set operating expectancies.
2. Analyze the equipment losses.
3. Develop (and rank) improvement needs and
