IATF 16949: 2016

This international automotive standard incorporates an emphasis on Total Productive Maintenance (TPM), its metrics, and overall proactive management of equipment and supporting processes. 

This is one of the most widely applied international quality management standards and is probably the most widely used. It helps to standardize the complex supply chain that stretch across international borders to hold all suppliers to a level playing field.

This website covers the section related to continuous improvement:


Within TPM there are three primary metrics that could be applied, but more could be used.

  1. OEE (Overall Equipment Effectiveness)
  2. MTTR (Mean Time to Repair)
  3. MTBF (Mean Time Between Failure)

Click on each to learn more and work through example calculations. OEE and MTTR are more reactive metrics, while MTBF is used to predict the next failure and apply preventive actions before that next failure, a proactive metric.

It's one thing to know when a failure will occur, then maintenance can be planned and take place just prior to the failure. But its also important to extend the MTBF as long as possible.

Predictive maintenance tools, such as oil analysis and thermal imaging, can be performed regularly to avoid unnecessary maintenance and monitor how changes in maintenance are affecting the equipment. 

The metrics are used as inputs into the Management Review, Section 9.3
