Capturing and Utilizing Failure Knowledge to Ensure Robust Design and Process

Richard Hage

This paper discusses integrated techniques for properly capturing and communicating knowledge of potential process and design failures. The techniques are tied together to ensure the best practices are encouraged and the worst practices are discouraged in the design and production of a product. It is important that such information be captured so the potential durability effect of variations in both product design and the production process can be understood. By having proper understanding of the design and process impact of changes, product and process optimization efforts can be optimized. Two tools were chosen for their utility towards identifying and capturing the relevant failure events. They are Failure Modes and Effects Analysis (FMEA) and Event tree diagrams. The FMEA functions as both a conversation tool and a documentation tool for capturing the failure possibilities of a system. Event tree diagrams are graphical means for representing the chain of events which can ultimately lead to product failure. The paper discusses how these two techniques can be used in concert to ensure proper capture and understanding of failure mechanisms. The methodology presented is currently being implemented across the insulating glass industry.
