Degradation Analysis in Destructive Testing
Degradation analysis is an important data analysis technique for projecting failure data from the degradation history of a quality or performance characteristic that is associated with the reliability of a product. This approach typically requires that the degradation be measured for multiple units over time. However, in some cases, destructive testing is necessary to obtain degradation measurements and taking multiple measurements over the life of the same unit is therefore not feasible. This article describes an approach, using Weibull++ 7 and ALTA 7, to handle such a data analysis problem and predict a failure distribution model.

Introduction to Design of Experiments (DOE) - DOE Types
This article continues the discussion of Design of Experiments (DOE) that started in last month's issue of the Reliability HotWire. This article gives a summary of the various types of DOE. Future articles will cover more DOE fundamentals in addition to applications and discussion of DOE analyses accomplished with the soon-to-be-introduced DOE++ software!

Tool Tips
  • Can I copy/paste more than one item in the System Hierarchy or FMEA Hierarchy in Xfmea or RCM++ ?
  • Where can I find examples to see how ReliaSoft software works?

New Symposium Format - ARS, North America 2008 promises to be better than ever this year! Due to popular demand, the schedule has been expanded to allow more presentations on reliability topics, more opportunities for building relationships with colleagues and one additional day for staying informed on the latest academic research. For more information, please visit


DOE Software from ReliaSoft! - The wait is nearly over now that ReliaSoft's new DOE++ is almost complete. This powerful new software facilitates traditional Design of Experiments (DOE) techniques for studying the factors that may affect a product or process in order to identify significant factors and optimize designs. In addition, DOE++ supports "Reliability DOE." This represents a major breakthrough for reliability-related analyses because only ReliaSoft's DOE++ provides methods for the proper analysis treatment for interval and right censored data. DOE++ also integrates seamlessly with Weibull++ and ALTA. The first training seminar for RS 588 Design of Experiments is scheduled for June 2 - 4, 2008 in Tucson, Arizona. For more information, please visit or go to to sign up now.


Final Reminder for FMEA Training Failure Modes and Effects Analysis (FMEA) is becoming increasingly important in many industries, because the potential benefits include superior designs for products and processes that can result in higher reliability, better quality, increased safety, increased productivity, enhanced customer satisfaction, improved morale and significantly lower costs related to warranty and maintenance. To learn more about the basics of FMEA, risk assessment and best practices, register for the upcoming ReliaSoft seminar RS 470 FMEA/FMECA and Xfmea scheduled for March 20 - 21, 2008 in Tucson, Arizona. For more information, please visit or go to to sign up now.
