A major challenge facing maintenance people nowadays is not only to learn what these techniques are, but to decide which are worthwhile and which are not for a particular asset. If we make the right choices, it is possible to improve asset performance and at the same time, even reduce the cost of maintenance. If we make the wrong choices, new problems are created while existing problems only get worse. The control of production processes is the subject of several disciplines. Although these disciplines are traditionally separated (both in science and in business practice), their goals have a great deal of overlap. Their common goal is to achieve optimal product quality, little downtime, and cost reduction, by controlling variations in the process. However, single or separated parallel applications may be not fully effective. So it is necessary to have integrated approach of TPM.
