Good FMEAs, Bad FMEAs - What's the Difference?
There are countless reasons to use Failure Modes and Effects Analysis (FMEA) in product development and operations. Whatever your reason, you believe FMEAs have the potential to achieve your goals … and you are right. However, there’s a caveat, and it’s a big one. Not everyone gets uniformly great results from FMEAs. They have to be done properly, with the right preparation, the right team composition and the right procedure. In addition, they have to be done in such a way that they don’t consume excessive time and money. Done correctly, FMEAs will save money, speed up product development, increase safety, and achieve high reliability in products and processes. However, done improperly, they can waste time and not add value. This article describes an auditing procedure based on ten quality objectives that will help ensure that FMEAs are effective in achieving quality and reliability objectives in your company.

Demonstrating a Difference in Life Using the Difference Detection Matrix
In the manufacturing industry, design/test engineers often need to design demonstration tests for devices and materials from different suppliers. To do this, they need to decide which sample size and testing time are most appropriate for the test. Weibull++8 has a new tool, the Difference Detection Matrix, which can help engineers make such decisions. The Difference Detection Matrix calculates how much test time is required before it is possible to detect a statistically significant difference in the mean life or BX% life (e.g., B10 life) of two product designs by analyzing the data from a reliability life test. The test engineer can use this tool to evaluate different test plans in order to choose the most efficient way to compare the reliability metric of two designs. In this article, we will use an example to illustrate how to use this new tool.

* Effective FMEAs Now In Stock!Effective FMEAs: Achieving Safe, Reliable, and Economical Products and Processes using Failure Mode and Effects Analysis by Carl Carlson is now available in our USA online web store at: Carl Carlson has extensive experience with thousands of FMEAs with dozens of companies, and he frequently teaches and consults at ReliaSoft. He has also created his Effective FMEAs website to provide not only information about the book, but also links to FMEA articles and a way to directly engage readers and answer questions:
* Congratulations to the 2012 ARS Excellent Presentation Award Winners! – Each year, engineers have the opportunity to present at one of the Applied Reliability Symposium (ARS) events held five times a year at locations around the world. One of the coveted goals for many presenters is achieving an ARS Excellent Presentation Award. The winners are selected based on votes cast by the attendees. Here are the winners from last month's event in North America:

  • James McLeish (Gold Award - $1000) from DfR Solutions for his presentation titled The Transition from MTTF Reliability Predictions to Physics of Failure Reliability Assessments
  • Stan Stephenson (Silver Award - $750) from Halliburton for his presentation titled Benchmarking Your Reliability Program: Are You Just Doing Things Right or Doing the Right Things?
  • Shawn McKay (Bronze Award - $500) from The RAND Corporation for his presentation titled Automated Identification of Parts with Poor Reliability and Their Cost Implications

* Awarded in Brazil – The Reliability Leadership Award, issued by ReliaSoft Brazil at ARS, recognizes companies that have excelled in the application of reliability engineering. This year, the South American award went to Metrô de São Paulo (Brazil) for their investment in training and certification for reliability professionals and by their investment in reliability tools, showing a multidisciplinary application in their reliability activities. This company has also presented case studies in sectorial events, contributing to the spread of reliability benefits.
* CRP Achievement Recognition – During the Applied Reliability Symposium (ARS) in Brazil, we had the distinct pleasure of honoring nine recipients of the Certified Reliability Professional (CRP) certification for their outstanding achievement in reliability engineering:

  • Edillon Pinheiro Silva
  • Cezar Mazzoni Navajas
  • Mauricio Cunha Fiock da Silva
  • Marcelo Sanchez Turrini
  • Pablo Alexandre Matos Barros
  • Patricio A. Meyer M.
  • Ulysses Monteiro Machado
  • César Augusto Lobato
  • Marcus Vinicius Xavier da Costa
