1 Failures simply won’t go away by fixing them all the time. We can only eliminate failures if we try to analyze them through Root Cause Failure Analysis. Then, only maintenance department can focus more on improving their asset performance.

2 To arrive at the correct solution to our equipment problemsRCFA is not about addressing all the probable causes but rather failures being looked back in reverse to determine what really cause the problem. In performing RCFA, each hypothesis is verified until we have gathered enough evidence that these are the actual facts that lead to the failure itself. In completely eliminating the problem, it is important to address not only the physical cause but both the human and the latent cause.

3 Equipment failures might induce the possibility of secondary damage. Parts that are in the process of failing such as bearings will increase the vibration of equipment, this increase in vibration would be harmful to other parts that are directly coupled to the part that induce the vibration. Oftentimes secondary damage will be more costly than the parts that initially failed

4 Being proactive will give me a sense of security. Many maintenance personnel believes that a good backlog of maintenance work will ensure them of their job security. This is not the right mindset. Traditional maintenance people is confined to repairs and fixing failures but the scope of our job is beyond boundaries, our real job is to improve our equipment reliability and the scope of maintenance is beyond boundaries CBM, Oil Analysis, Lubrication, Tribology, Coaching their Operators on Basic Equipment Condition, Oil Contamination Control, Spare Parts Management, Maintenance Cost Reduction Team, just to name a few.

5 We all learn from the failure itself.

For every failure that occurred and that had been thoroughly analyzed through RCFA, there is a learning that we can all can gained from these experience in order to prevent the recurrence of the failure itself. Sometimes failures speak to us in a different language.
