Steps for FMEA

Step 1: Process review
Step 2: Potential failure modes
Step 3: Potential effects of each failure mode
Step 4: Assign a severity rating
Step 5: Assign an occurrence rating
Step 6: Assign a failure rating
Step 7: Calculate the risk priority number (RPN) for each effect
Step 8: Prioritise the failure modes
Step 9: Take action to reduce or eliminate the high risk failure modes
Step 10: Recalculate the RPN
