Additional Information

Introductory letter from Dean V. Davis Ph.D. Process Analytics Quality Manager

Siemens is pleased to announce to our customers a new improvement in Siemens quality processes.  Siemens has now established a procedure by which customers can submit failed parts for detailed failure analysis. 

All Siemens parts are designed to have very high reliability and field failure is not expected to occur often.  However, Siemens desires to ensure that these design goals are continuously achieved in actual field service.  Therefore, this procedure is useful when customers believe they are seeing repeated or similar failures of a particular part which might indicate a change or decline in normal parts quality.  Using this method, customers can assist in calling Siemens’ attention to such possibilities, and help ensure that Siemens parts maintain highest performance and reliability.
