Total questions: 15
Worksheet time: 8mins
The probability of a failure mode occurring due to its related cause is ________
Severity
Detection
Occurrence
Action priority
Failure mode and effect analysis (FMEA) provide a checklist procedure. Which of the following questions is NOT likely to feature on the checklist?
What would be the cost of avoiding failure?
What would the consequences of the failure?
What is the likelihood that failure will occur?
How likely is such a failure to be detected before it affects the customer?
Failure modes is defined as
any physical process, chemical process, design or any factor that is the basic reason for failure or deterioration that leads to failure
consequences of the product failure on the function, operation or process on the overall system and on the customers
the manner in which the process could cause the product not to deliver or provide intended function
none of the answer
State occasions that require FMEA to be updated.
When the product or process is modified or redesigned/ When any operating condition of the process is changes
When the previous FMEA is considered outdated (it exceeds the time interval)
When complaints from customers are received/ When any error or discrepancy in the FMEA table is identified
All the above

Quality engineer
Manufacturing engineer
Process variability data
A particular product has been given the following rankings for
calculating AP while preparing FMEA chart, S=10, O=2, D=6. What is
the value of RPN?
18
120
60
If a process has a '10' scale rating, what is the likelihood of detection?
Almost Certain
Almost Impossible
Very Low
Very High
If a process has a '1' scale rating, what is the occurence condition?
Occasionally happen
Failure is eliminated through preventive control
Always happen
Isolated case happen
According to common industry scale, what does severity ranking (S) 1 indicate?
Very serious effect
Sometimes serious effect
No effect
The value doesn’t exist
When PFMEA need to review?
i) Notable incidences of process abnormalities and customer complaints
ii) When the process failure mode against which a countermeasure has been taken occurs
iii) When process or work method is changed
iv) When changes happen related to customer requirement for existing product
i, ii & iii
i, iii & iv
i & iii
All above
What is the requirement to be included in current process control?
i) Prevention control
ii) Correction control
iii) Detection control
iv) Continuous improvement
i & iv
i & iii
i, ii & iii
All above
The PFMEA is a living document and should always reflect the latest design level as well as the latest relevant actions, including those occurring after the start of production.
True
False
