Maintenance has a far greater impact on corporate profitability than most managers are willing to consider, much less admit .And, as the competitive environment in the world continues to increase the pace, companies are looking for new strategies to save on costs, develop employees to face future challenges and bring about a new culture at work place. This has become imperative to stay in business and have an edge over the competition. In this situation, a number of strategies like Total Quality Management, Kaizen, quality circles, ISO certification, six sigma and Total productive Maintenance are available and it is the management choice to selectively implement these in their workplace.
What is TPM ?
Seiichi Nakajima (1988) has defined TPM as an innovative approach to maintenance that optimizes equipment effectiveness, eliminates breakdowns, and promotes autonomous maintenance by operators through day-to-day activities involving the total work force. Thus, TPM is not a specific maintenance policy, it is a culture, a philosophy and a new attitude towards maintenance. The salient features of TPM is the involvement of operators in carrying out autonomous maintenance by participating in cleaning, lubrication, minor repair, adjustments etc. The benefits of TPM can be very tangible. There are organizations, which through implementation of TPM have been able to increase the production volume by 50%. Reduce down time by 27% and rate of defective products by 80%. In addition to tangible benefits, TPM also various intangible benefits such as fostering of teamwork, increase morale, safety and nurturing the work force increased intellectual capabilities having the potential of meeting today's level of competition and challenges.
Evolution Of TPM
TPM descends from Japan and came into existence in the seventies. After Dr W Edward Deming made an impact in Japan through his teaching of quality, Japanese organization felt a need for autonomous maintenance and small group activities to support the quality movement. Today thousands of organizations all over the world are implementing TPM and about 100organisations are now doing it in India.
Total productive maintenance (TPM) is a proven strategy for medium to large industries to get superior business results and develop people skills to take on future business Challenges. Unlike ISO certification process, in TPM, focus is on maintaining the equipment and process in perfect condition- to get best quality products and involve all employees in Collectively carrying out loss elimination, using analytical problem solving tools. The fundamental belief is that if the equipment is maintained well and setting is done by a conscious, skilled operator, once can get the best quality product. The whole concept of TPM is built around this belief and hence the name total productive maintenance. However, this concept can be applied to places other than plant and equipment and instead we could name Total productive Management rather than just maintenance.

TPM definition (1)
A company-wide team-based effort to build quality into equipment and to improve overall equipment effectiveness
all employees are involved
it aims to eliminate all accidents, defects and breakdowns
actions are performed while production goes on
troubles for production are minimized
keep in good condition
repair, clean, lubricate
TPM combines the traditionally American practice of preventive maintenance with Total Quality Control and Total Employee Involvement, to create a culture where operators develop ownership of their equipment, and become full partners with Maintenance, Engineering and Management to assure equipment operates properly everyday.
Origins of TPM
Dr. Deming introduced statistical analysis and used the resulting data to control quality during manufacturing (TQM)
Some general concepts of TQM did not work well in the maintenance environment
The need to go further than preventive maintenance was quickly recognized by those companies who were committed to TQM
Maintenance became an integral part of TQM in the early 90’s
Increase Overall Equipment Effectiveness (OEE)
Improve existing planned maintenance systems
The operator is the best condition monitor
Provide training to upgrade operations and maintenance skills
Involve everyone and utilize cross-functional teamwork
Increased equipment productivity
Reduced equipment downtime
Increased plant capacity
Lower maintenance and production costs
Approaching zero equipment-caused defects
Enhanced job satisfaction
Increased Return On Investment
