I know I got a little frustrated with the posts going on in the "Sometimes you just get frustrated" thread but I was doing some research for an STLE presention and thought I would validate my friends who I might have been too critical of.

We asked 100 maintenance professionals: What percent of the time, when maintenance work is identified using PdM Technologies, does a failure occur before the repair is made?

• 0% answered - 0% of the time
  
  
• 60% reported that it occured less than 10% of the time - 60%
  
  
• 40% reported more than 10% but less than 30% of the time
  
  
• 0% reported that it occured more than 30% of the time
  

It seems like no one is perfect (surprise) and some do pretty good but many face the same problems as started the orginal thread.

By any chance do you have the data broken down for in-house analysts versus consultants?

Robert

No the data did not include a difference between in house and out of house.

I would guess it was a mix.

I do think there is a significant in house program population in this study.

I would be interested in a breakdown of the reasons for the failure after a warning.

Was the poll that specific?

I would expect a majority were due to financial or manpower issues like production not allowing a shutdown, no money in the budget, no people to do the job.

BTW, I would have been in the less than 10% catagory

Interesting the way the survey was worded. Had you used the Pareto (80/20) principle to formulate your question, I predict that 80% would have responded "less than 20%" of the time ....

Also, 20% of the machines are responsible for 80% of the problems.

Of the problems, 80% are correctable before a failure or collateral damage occurs.

Of the 80% of the machines that account for only 20% of the problems, only 20% will ever experience a significant event, even if no PdM is performed on them. That is, 64% (80% x 80%) of machines will never experience a failure if only routine maintenance (grease, belts, adjustments) is performed.
