Failure mode and Effect analysis

QUESTION 4 4.1 Explain the concept of Failure Mode and Effect Analysis (FMEA). (3) 4.2 A failure mode and effect analysis was performed on a product that will be produced by an equipment company. The analysis resulted in the identification of eight possible failure modes as detailed in the below table. Failure mode Occurrence Potential effects Severity Detection 10 7 Electric shock 5 5 8 8 9 Potential death to user Inability to use Loss of fingers Inability to use Inability to use Reduced utility Injuries to user 4 8 Casing fracture Finger pinch Motor failure Transmission failure Mechanism binding Sharp edges on casing Premature actuation W W 0000 7 8 1 6 7 9 7 Injuries to user 9 7 Determine the following: (8) 4.2.1 Calculate the Risk Priority Number (RPN) for each failure mode. 4.2.2 Determine which three failure modes are the most important to analyse and develop (in table form) a control plan for each. 4.2.3 Identify all the failure mode(s) that seem to be unimportant according to the RPN analysis.
