Phase one of the TPM process is to benchmark the current preventative maintenance program. The next step is to create and inventory list of the equipment used. The equipment list shall include the critical path equipment where there is no back up equipment, the support equipment, and the building utilities equipment. An ongoing audit process could be used to monitor the effectiveness of the equipment. The current maintenance program should be evaluated. The maintenance records can be examined to determine if changes are needed. Predictive maintenance measures physical parameters against expected standards to detect, analyze, and correct equipment problems before production loses occur. Diagnostic tools such as vibration monitoring and lubricate sampling methods can be used to detect problems before there is a failure.
