Comparison between TPM and TQM

Both TPM and TQC are aimed at corporate improvement. However there are slight differences.

1. The subject of management is quality in TQC and equipment in case of TPM.
3. TQC aims in management that implements systematisation and standardisation. TPM aims in realisation of proper form of equipment and work place.
4. TQC imparts personnel training in QC Techniques while TPM imparts training in maintenance engineering and maintenance skills.
5. TQC aims in voluntary QC aids but in TPM small group activities are integral part in how work place is organised.
6. The goal of TQC is quality while TPM aims in elimination of loss and waste.
7. TQC aims in process inspection and proof mechanisms TPM aims in condition based maintenance and preventive maintenance and maintenance prevention.
8. TQC makes use of statistical process control/control charts TPM makes use of machine failure records/MTBF.

It is observed that TPM makes use of some of techniques of JIT and TQC but relates them specifically to equipment management. For instance:

1. Life cycle planning used to predict the maintenance needs of equipment throughout its lifetime.
2. Design of virtually maintenance free equipment

Man-Quality-Machine (MQM) management which in order to ensure defect free products, analyses interface between maintenance, product quality, machine parts and links, specific maintenance procedures, machine actions.

As with JIT and TQC process, TPM process is driven by employee involvement at all company levels. TPM transfers primary responsibility for machine maintenance as close to action as possible to the machine operators. The goal of this responsibility transfer is to develop highly coordinated approach to productive maintenance, where everyone works together as a part of improvement process. Another key component of TPM is education and training. To fulfil their newer possibilities, operators are given in house instruction for correct operating practices and simple repairs.
