【正文】 ition FMEA__ Potential Failure Mode __ Potential Failure Effect__ Severity__ Cause__ Occurrence__ Detection__ Risk Priority Number__ a. A assessment of the seriousness of the effect of the potential failure mode b. A systematic analysis of a process used to identify potential failures and to prevent their occurrences c. The likelihood that a specific failure mode is projected to occur d. The project of Severity * Occurrence * Detection e. How the failure could occur, described in terms of something that can be corrected or controlled f. The manner in which the process could potentially fail g. The effectiveness of current process controls to identify the failure mode (or the failure effect) prior to occurring, prior to release to production, or prior to shipment to the customer h. The results of the failure mode to the customer (RPN) 3. When using the RPN number to prioritize the actions to be taken, what is a potential shorting of the RPN number? a) It does not prioritize to the safety issue, if there are low occurrences and detection scores b) It does not always reflect the true view of the customer c) It does not identify the underlying cause d) It needs to be updated regularly 26 練習 1 type of FMEA is most likely to use? a) Design b) Process c) System d) All of the above 5. Which of the following concepts would a typical FMEA investigate? a) Process Flow b) Analysis of Complex Systems c) Subsystems d) Equipment e) Parts in Early Design Stage f) Gauges g) Process Inputs 6. What is the purpose of a FMEA? a) To fully document all the steps in a process b) To drive improvement c) An iterative brainstorming tool used to define final product functionality d) To record effects of improvement undertaken during the Six Sigma Project e) To simply evaluate the possible failure conditions of a process is the primary output of the “Initial Assessment phase” of an FMEA? a) To list all inputs to the process b) Rank inputs by the severity of their failure effect c) To brainstorm all process controls d) An RPN number to identify the critical inputs by their effect are the steps for the “Process Function” column selected? a) Those process steps that add value to the final product b) The highest ranked process steps identified from the Camp。1 失敗模式及影響分析 (FMEA) 品質(zhì)工具培訓 2 培訓目的 完成本課程的學習后 ,我們可以 …… FMEA.
