2
Popcorn Sample PFMEA: PFMEA Body
* Review Process Steps * Review Associated Potential Failure Modes * Review Associated Effects * Review Associated Causes * Review Associated Controls
3
Popcorn Sample PFMEA: Risk (RPN)
* Review Severity Ranking * Review Occurrence Ranking * Review Detection Ranking * Review RPN Calculation
4
Popcorn Sample PFMEA: Corrective Action
* Review High RPN Values (High Risk) * Review Corrective Actions
5
Popcorn Sample PFMEA: Control Plan
* Translate Corrective Actions and Controls into a Quality Control Plan
6
Group Project Hose Valve PFMEA:
* Develop a Process FMEA for a Garden Hose Valve Assembly * Work Groups of Five * One Person is the Recorder * Use Brainstorming Technique, Take Turns * Remember, There are No Bad Suggestions
7
Hose Valve PFMEA: Product Review
* Review Hose Valve Assembly and Function * Remove Large Flat O-ring * Remove Screw and Lever * Remove Valve Ball * Remove Small O-ring
8
Hose Valve PFMEA: Specifications
* Review Customer Specifications * Specifications are the Criteria for Failure Modes * Which Specifications are Design and which are Process? * Which Specifications can be Translated into Controls?
9
Hose Valve PFMEA: Process Flow Diagram
* Review Process Flow and Operations * Notice Required Tools/Equipment * Notice Control Characteristics * What Needs to be Added...PFMEA to Determine
10
Hose Valve PFMEA: Process Operations
* List Process Steps in FMEA and Number * One Process Step Per FMEA Page
11
Hose Valve PFMEA: Failure Modes
* List Failure Modes Associated with Process Step * Brainstorm and Discuss...is it Realistic? * Try Assembling per Process Flow Steps
12
Hose Valve PFMEA: Effects, Causes, and Controls
* List the Effects of the Failure Modes * List the Root Cause of the Failure Modes * List the Control Mechanisms to Prevent or Detect the Failure Mode
