Failure Mode Effects Analysis内容提要：
Cross Functional and Multilevel
Operators, Mechanics, Engineers, Leaders
Team Leader Designated
Recommended to be Process Owner
Must be Empowered to implement actions
Functional experts can be pulled in as needed
Smaller “Core” group may be useful initially to provide framework.
Develop a Process Flow diagram that is representative of the process as it truly is.
Decide the Rating Scales
Outline Operator, Machine, Product Interactions
Evaluate effect of actions taken on process in terms of severity, occurrence and detection.
Recalculate RPN and reassess risk number.
Reprioritize and repeat.
The problem, the concern, the opportunity to improve, the failure, the reject.
Think of the specific loss of the process function.
Example Questions:
How could this process fail to complete its intended function?
Why could this part be rejected at this operation?
What does the customer (internal or external) find unacceptable?
How would the part not conform to specifications at this operation?
A method, procedure, test or engineering analysis designed to catch the problem before it reaches the next operation or customer.
Can be simple, ex. Audits, sampling, sensors, SPC, operator checks, in process tests, fixturing.
Can be complex, ex. FEI, Mil Standards, Computer Simulation, Laboratory Tests.
Focus for the detection rating is in the effectiveness of the control to catch the problem before it reaches the customer.
