FMEA

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• When the previous FMEA is considered outdated (it exceeds the time interval)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

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 AP?

• L

• M

• H

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
