Data and Automation of Analysis
Kirk and Fred discussing the use of current buzzwords in the field of reliability, the use of software data Failure Reporting and Corrective Action Systems (FRACAS) and how many reliability professionals jump to software automation to analyze reliability issues.
Join Kirk and Fred as they discuss how when it comes to understanding reliability you must understand the basic physical causes of failure through empirical failure analysis.
- Some would promote that the software analysis of field failure data may give a better graphically illustration of the extent and distribution of a problem, but in most cases failures can be understood with FA of a very small sample. A pretty graph may not add much to solving the problem.
- Understanding where and why the failure data is gathered on manufacturing lots and dates may help identify a regional, it may identify a problem with a regions pour power distributions or special environmental conditions but sometimes may not have a correlation at all. Electronics used in a Seaside environment have a much higher failures due to corrosion.
- Reliability Engineers many times want to jump to models rather than go examine failed systems from warranty returns, and actually take systems apart to isolate and understand what physical mechanisms cause the system to stop working.
- An advantage of finding the failure cause and repairing capital equipment on site is being able to develop a new relationship with the customer and re-sell the customer the reliability of the system after they have lost faith in its reliability due to the failure.
