Alaa,

Your CMMS should have a KPI to show rework as the technician defines it, but another way to look at this issue is to look at equipment with highest failures as a KPI, and then look at the detail of the who what when and why. Depending on a technician to mark an work order as rework can lead to missed information.

Dear Ala,

In my view, the rework KPI should be evaluated within a time window that truly reflects the quality of the maintenance process. Based on SMRP best practices and what we typically observe in mature organizations, a window between 30 and 60 days is the most representative for capturing failures related to assembly, inspection, or the overall quality of the work performed. Shorter windows help identify immediate errors, while slightly longer ranges allow detection of issues that develop progressively. The most important point is to maintain a consistent, documented criterion aligned with the criticality of the equipment.

Alaa,

My understanding of your question is that you are asking if there is a defined time window, following maintenance work being completed, that defines equipment failure as Rework.  In my experience the answer is no.  If the equipment fails, after maintenance, in a time significantly less than the expected time it should operate with our failing, it may be a Rework case.  The cause of the failure is important.  If the equipment fails because of an operator error or some external cause (e.g. lightening strike) then it is not Rework.  If the equipment that was worked on fails due to not being reassembled properly, use of the wrong replacement part or due to internal contamination those would be Rework.  The Root cause might be a lack of documented spare parts, poor documentation in the maintenance procedure (if there is one) or lack of sufficient training for the personnel.

In the end, the Cause of the failure is what the people responsible for Reliability can address, whether it is Rework or not.  The Rework metric should draw managements attention to the Cause so that mitigating actions can be taken.
