Guys, there is some confusion in our plant regarding when to generate a breakdown work order and when to generate a corrective repair work order.
My understanding (and please correct me if I'm wrong)is the corrective repair is generated when a potential breakdown is discovered through PM / Pdm, and fixed before functional failure.
A breakdown work order of course is only generated after a functional failure.

I'm my plant we dont have a different maintenance order code, or type, for breakdown vs corrective; both are called corrective.

However, I agree with you. If I would separate these orders, the breakdown orders would be for those events that the equipment can not be left in operational until the repair is completed.

Mike66,

Maintenance work can be done
1. Before failure has been initiated, in anticipation of it: this is Preventive
2. After failure has been initiated, and the degradation has commenced, but has not progressed so far that the item does not meet specified output. In this case, condition monitoring or predictive maintenance(PdM) is the best option. If the PdM readings suggest repair action, such Work Orders are Corrective.
3. To detect a hidden failure; if item is found to be in a failed state, the replacement action is Corrective.
4. After the item fails to do its job (functionally failed)i.e., the item has broken down. In some organizations, the term Breakdown Maintenance is used, others call it Corrective Maintenance. Choose whatever suits you, as long as everybody in your organization understands what you mean. My preference would be to call it Breakdown.

I did not mentioned, when the equipment breaks down we ask the user to document at the Maintenance Notification or Request the start date/time of the breakdown, however the order is still classified as Corrective Maintenance.

Thanks Vee and Eugene for your views.
I agree with your interpretations of PM work orders - we use these just for doing the inspections. Once a fault is found we then generate the corrective repair work order.
The reason for this is it allows us to map the effectiveness of our programme eg CR workorders vs BR workorders. However if we do not have these defined properly then how can we measure?

I also like your comment Eugene on Breakdown reports - I think this is what you mean - and we are looking to get this happening as part of our procedure.
When we have a breakdown the fitter(mill wright) or electrical has a simple breakdown form to record the following:

Date and time of breakdown.
What it was or location
Time to fix (for MTTR)
Description of problem
Countermeasure.

I think it is good as you say to not only record this for breakdowns but also corrective.

Thankyou for your feedbacks.

Mike.

In our CMMS the start of breakdown reported by the requester at the maintenance notification gets tied with the date at time of the corrective order to calculate the time to fix. With the equipment number at the notification the what it was and the location is known; the notification also provides the description of the problem which is later confirmed or corrected by the comments of the Maintenance Technician at the order. The countermeasure (at least from Maintenance is tasks at the corrective order).
