IATF 16949 Section 8.5.1.5 (Total Productive Maintenance)

Section 8.5.1.5, Total Productive Maintenance, of the IATF 16949 standard has a requirement that states that the total productive maintenance system shall include f) documented maintenance objectives, for example: OEE, MTBF, MTTR, and Preventive Maintenance compliance metrics.

Since the requirement states "for example" for the maintenance objectives, does this mean that these are suggested metrics but not required metrics?

You are right, but if they were worth to mention there, so we should treat them as "state of art" metrics. Probably our own metrics (if other than these one) may not be "better", so we should consider switching to these mentioned by IATF 16949.

IATF is giving some expected metrics - Note: "... system shall include ...". In short, those and other metrics each company must determine is applicable to their equipment. It would be good for an IATF 16949 player to say, but I *assume* OEE, MTBF, MTTR, and Preventive Maintenance compliance metrics are minimum mandatories.

My introduction to automotive was the late 1980's. Over the years so much as changed, so much has been learned, and so much is available to companies (such as good software) that, for example, OEE, MTBF, and MTTR are better understood and easier for companies of all sizes to compute and track.

I pretty much agree with Sebastian - Companies should treat them as "state of art" metrics. That's not to say in some cases various metrics are not of significance - That is something each company has to decide.

It is not a must because these are just examples. You can set you own objectives based on your own needs. We have OEE, maintenance cost as our key objectives.

IATF 16949 Interpretation - 8.5.1.5 "Total Productive Maintenance"

I am confused. IATF 8.5.1.5 "Total Productive Maintenance"

"At a minimum, the system shall include the following...f) documented maintenance objectives, for example: OEE, MTBF and MTTR and preventive maintenance compliance metrics." Can I infer that if we are already tracking objectives such as unplanned downtime, PM completions to schedule, plant improvements, etc., that we are not required to do OEE, MTBF and MTTR?

Also, item j) refers to "periodic overhaul". What is this refering to?

Just an FYI. According to a webinar I attended this clause has raised the most nonconformances in the audits already completed.

That is correct! Maintenance, the red-haired stepchild in many organizations.
Predictive and Preventive maintenance, still NOT effective.

Well in my dealings with auditors, both good and bad, they don't know the first thing about actual maintenance. They have read it in a book or learned it a seminar, but have no practical experience. I had one try to tell me that monitoring our bearing clearances and parallelism on a punch press was not getting it done, when that is the most important thing you can do on that equipment.

My company had a non conformity at this item.
The auditor saw all documents that evidence compliance to 8.5.1.5, but reported that we had no evidence of a documented process.
In other words ...he wants to see a procedure or, as a minimum, a flowchart for this section!
Can anybody help me with this, have you an exemple of a procedure or a flowchart that can be shared?
