Concepts of Total Productive Maintenance -Topic - 3 : Difference between TQM and TPM Concepts

Difference between TQM and TPM

Total Quality Management and Total Productive Maintenance are often used interchangeably. However, TQM and TPM share a lot of similarities, but are considered as two different approaches in the official literature.

Focus of Total Quality Management Concept

TQM attempts to increase the quality of goods, services and concomitant customer satisfaction by raising awareness of quality concerns across the organization.
TQM is based on some specific corner-stones:
Design excellence,
Product excellence,
Process excellence,
Marketing excellence,
Customer experience,
The organizational environment,
Leadership commitment that guides the organization, and
Commitment to excellence throughout the organization at all levels.

Focus of Total Productive Maintenance Concept : 

TPM focuses on operational excellence through achievement of 4 Zeroes such as
Zero Breakdowns
Zero Defects
Zero Accidents and
Zero Losses
TPM is aimed at the overall pursuit of production efficiency, improvement to its maximum extent. By preventing equipment break-down, improving the quality of the equipment and by standardizing the equipment (results in less variance, so better quality), the quality of the products increases.

The basic difference between these two programs can be sighted in a summarized tabulated form as  shown below : 
Table. 1.  Difference between the approaches - TQM   and TPM

Apart from differences TPM and TQM program also carries certain similarities between them : 

    • Both the management improvement programs uses tools like employee engagement and employee engagement, benchmarking, target setting, data capturing and trend reviewing, systematic management review mechanisms and fact/ data based decision making etc.
    • Both the programs demands highest degree of top management commitment for their success.
    • Training of employees and engaging them with small grouped activities related to continuous improvement. Both the programs adopts reward and recognition mechanism to ignite employee enthusiasm for participation in improvement initiatives.
    • Both the programs are long term vision oriented, takes quite a good time (approximately 3 to 5 years) for their implementation, call for a higher level of accountability and commitment from the regular employees, beyond their job responsibility. Once implemented bothe the programs are to be practiced for life time to  be able to receive continuous results.
TQM and TPM can both result in an increase of quality, performance, and productivity and customer orientation and both the concepts if deployed holistically in any organization, the organization receives immense amount of benefit out of it. However, the way of persuasion towards both concepts  are different different. But from experience I must say TPM can be seen as a way to help achieving the goals of TQM.

In my next blog I will talk about concepts of 12 step TPM Implementation Program ( Link:12 Steps of TPM Implementation Program) and  TPM pillars. ( Link : 8 Pillars of TPM)
