ROOT CAUSE ANALYSIS

HAVING THE SYSTEM QUERY THE ROOT CAUSE ANALYSIS:

• THE FOLLOWING PARAMETER IN THE COMPANY PARAMETERS MUST BE ACTIVE

WHY ANALYSIS CAN BE QUERIED IN THREE WAYS.

OPTION 1) LET A FAILURE RECUR IN EVERY ASSET WITH A MAXIMUM OF X LIMIT, REGARDLESS OF ANY ENTITY. IF I SAY WHY THE ANALYSIS SHOULD BE QUESTIONED WHEN IT EXCEEDS X, I SHOULD PROCEED WITH THIS OPTION. MAINTENANCE MANAGEMENT''>'''I ENTER INTO THE RELEVANT FAULT '>``````>' I DEFINE THE "110V DC SUPPLY" FAILURE 3 TIMES IN EACH ENTITY, AND WHEN IT IS 4, MAKE THE ROOT CAUSE ANALYSIS QUESTION.

IF THIS CAUSE OF FAILURE OCCURS FOR THE 3RD TIME IN EVERY ASSET REGARDLESS OF THE ASSET, IT DOES NOT ALLOW THE 4TH FAILURE IN THE SAME ASSET TO CLOSE, IT IGNORES THE FOLLOWING WARNING AND QUESTIONS THE ANALYSIS OF THE CAUSE.

OPTION 2) I DON'T WANT TO QUESTION THE ANALYSIS ON EVERY ASSET WHEN MY REASON FOR FAILURE EXCEEDS THE LIMIT OF 2 I JUST HAVE A SPECIAL ASSET I NEED TO PROCEED WITH THIS OPTION IF I WANT TO QUERY THE ANALYSIS WHEN IT EXCEEDS THE LIMIT I HAVE ENTERED. IF I SAY "WHY SHOULD I QUESTION THE ANALYSIS IF IT HAPPENS 3 TIMES, LET THIS FAILURE IN THIS ASSET HAPPEN A MAXIMUM OF 2 TIMES" WITHOUT GIVING A DATE CRITERION, I NEED TO PROCEED WITH THIS OPTION. IN THE "FAILURE CAUSE REPETITION LIMITS" TAB IN THE ASSET CARD, THE MAXIMUM FAILURE RELATED TO THE ASSET IS MATCHED.

IN THE EXAMPLE I GAVE ABOVE, THE CAUSE OF FAILURE IN THE PRESENCE OF COMPRESSOR WITH CODE "10" IS THE CAUSE OF "24V DC SUPPLY FAILURE" MAXIMUM 2 TIMES. WHEN IT HAPPENS FOR THE 3RD TIME, WHY SHOULD IT QUESTION THE ANALYSIS""

IF I SAY "WHY SHOULD I QUESTION THE ANALYSIS IF IT HAPPENS 3 TIMES, LET THIS FAILURE IN THIS ASSET HAPPEN A MAXIMUM OF 2 TIMES" WITHOUT GIVING A DATE CRITERION, I NEED TO PROCEED WITH THIS OPTION. I HAD A FAILURE OF MY COMPRESSOR CODE 10 3 TIMES WITH THE SAME FAILURE CAUSE (24V DC SUPPLY FAILURE). I DID NOT RECEIVE ANY WARNING WHEN I HAD THE MALFUNCTION 2 TIMES AND SHUT IT DOWN. WHEN I WENT THROUGH IT FOR THE 3RD TIME AND TRIED TO CLOSE THE FAULT, HE WARNED ME WHY I SHOULD QUESTION THE ANALYSIS.

WHY WILL HE NOT LET ME CLOSE HIS ANALYSIS WITHOUT QUESTIONING IT.

OPTION 3) IF I WANT THE FAILURE CAUSE I HAVE CHOSEN FOR THE ASSET I HAVE SELECTED TO BE ENCOUNTERED NO MORE THAN y TIMES IN X DAYS, I SHOULD PROCEED WITH THIS OPTION. WITHIN 15 DAYS, I MUST ENCOUNTER THE CAUSE OF THE "BATTERY BROKEN" FAILURE NO MORE THAN 4 TIMES IN THE SAME ASSET. IF I WANT TO FIND THE ROOT CAUSE WHEN I MEET FOR THE 5TH TIME ASSET MANAGEMENT''>''>'>'

IF THIS ASSET EXCEEDS THE REPEAT LIMIT OF THE RELEVANT FAULT WITHIN 15 DAYS, THE FOLLOWING WARNING IS RECEIVED AND PERSONNEL ARE FORCED TO INQUIRE ABOUT THE ROOT CAUSE.
