Variability Analysis in DOE++ and its Application
DOE++ offers the option of variability analysis for two level factorial designs and Response Surface Method designs. Variability analysis can be used to study the natural variation in the response for a particular combination of the levels of the investigated factors. This article illustrates variability analysis in DOE++ using a two level full factorial experiment as an example. Note that to conduct a variability analysis, it is important to have a replicated experiment (or multiple readings taken at all factor level combinations in a random order [1]).

Individual and Joint Parameter Bounds in Weibull++
Weibull++ can provide both individual and joint parameter bounds for a given data set. This article briefly explains the difference between these bounds with respect to their calculation and application. The article also provides step-by-step guidance on how to obtain these bounds using Weibull++.

* Congratulations to ARS Award Recipients - In recognition of significant contributions they have made to the field of reliability engineering and to the 2009 Applied Reliability Symposium in San Diego, we had the distinct honor and pleasure of awarding both individuals and companies as follows:

2009 Reliability Leadership Awards - Presented to two companies in recognition of their outstanding efforts in the area of Design for Reliability (DFR):
  • Glenn Baker accepted on behalf of John Deere
  • Julio Pulido accepted on behalf of Ingersoll Rand
Both companies understood the need for knowledgeable engineers to drive the DFR process and implemented corporate-wide training programs to accomplish this goal.

2009 ARS Excellent Presentation Awards - Based upon votes cast by those attending ARS, the following presentations were selected as the top three:
  • Gold ($1,000): William H. Farr, Naval Surface Warfare Center, "Software Reliability Assessment: Achievements and Challenges"
  • Silver ($750): David C. Trindade, Sun Microsystems, "How Statistical Modeling of Field Reliability Failures Guided Efforts on Problem Resolution"
  • Bronze ($500): Mike Silverman, Ops A La Carte, "Developing a Better Reliability Test Program"
Details and some pictures related to the awards presented this year are available online at
* CRP Achievement Recognition - During the Applied Reliability Symposium (ARS) in San Diego, we had the distinct pleasure of honoring two individuals for their outstanding achievement in completing the certification requirements for the Certified Reliability Professional (CRP) program:
