Failure Modes and Effects Analysis - answer-FMEA Stands for
1. It is a structured proactive approach to identify and estimate ways the product or process can fail,
then plan and prioritize to prevent those failures - answer-FMEA:
the manner in which a product or process can fail to meet specification - answer-FMEA, Failure mode:
Impact on customers (downstream customers or ultimate customers) if failure mode is not prevented or
corrected - answer-FMEA Effects:
1. Identify potential failure modes, ways in which the product, service, or process might fail
2. Identify potential effect of each failure (consequences of that failure) and rate its severity
3. Identify causes of the effects and rate their likelihood of occurrence
4. Rate your ability to detect each failure mode
5. Multiply the three numbers together to determine the risk of each failure mode (RPN = Risk Priority
Number)
6. Identify ways to reduce or eliminate risk associated with high RPNs - answer-How to conduct FMEA:
1. Relates to the FMEA
2. Severity = Likely impact in the future
Rating 10: Injure a customer or employee
Rating 8: illegal
Rating 2: Be unnoticed, minor effect on performance
Rating 1: Be unnoticed and not affect the performance - answer-What is the severity rating and what
does it relate to
10 Rating:, Time: period more than once per day , Probability > 30%
9 Rating:, once every 3 days, < 30%
Rating 8: once per week, Probability < 5%
Rating 1, Once every 6 years <= 2 per billion - answer-Occurrence Rating Scale
What does it relate to and the scoring system?
1. Standardize
, 2. Document
3. Training
4. Control - answer-Steps of the control Phase:
oTo make sure that our process stays in control after the solution has been implemented
o To quickly detect the out of control state and determine the associated special causes so that actions
can be taken to correct the problem before nonconformance are produced - answer-The Goal of the
Control Phase
standard operation procedures - answer-SOP stands for
Normally 7
Step 1: Document the work context of the procedure
Step 2: Collect documents that represent the procedure
Step 3: compare the documented procedure with the actual procedure
Step 4: Reconcile actual practice with the documented procedure
Step 5: Plan to use the documented procedure
Step 6: Use the standard procedure
Step 7: Check on the use of the standard procedure - answer-SOP Steps:
Plan-DO-Check-Act
* it is continuos - answer-PDCA stands for:
1. understand what data to monitor and how to monitor
2. If a standardized process fails, we need to know how it failed in that instance, what can be done to
improve the process so the problem does not repeat - answer-What PDCA does:
1. Henry Ford
2. Toyota - answer-What organizations started Lean
1. Motorola - answer-Who started six sigma
on eliminating wastes and improving efficiency - answer-Lean focuses on?
on reducing defects and variation - answer-Six Sigma Focuses on:
