Root Cause Failure Analysis

Root Cause Failure Analysis is an intense 2-day program that integrates Engineering, Quality Assurance, Manufacturing, Manufacturing Engineering, and Supply Chain efforts to identify and eliminate root failure causes occurring in complex systems, subsystems, and components. The approach relies on fault tree analysis for identifying all potential failure causes and an associated set of technologies for evaluating each hypothesized potential cause. Hardware analysis, statistical analysis, design of experiments technical data package evaluation, and other technologies are combined to provide an effective root cause failure analysis procedure for manufacturers, process industries, and other technology-based organizations.

We will tailor this training to your industry and your specific needs. This is not just another canned "make your problem fit our solution" training program. It may well be the most valuable training your organization ever receives.

We literally "wrote the book" on root cause failure analysis (click on the photo to the right to order a copy) based on decades of experience...experience and knowledge you can put to work in your organization!

The Root Cause Failure Analysis program provides students with the ability to:

• Identify dominant failure modes through quantity and cost-based Pareto analyses

• Identify the root causes of systems failures

• Select and implement effective corrective actions

• Work as an inter-organizational, multi-disciplinary failure analysis team

Course prerequisites include a four-year technical degree or equivalent industrial experience in an engineering or manufacturing environment.

Industry-based case studies are utilized extensively in the Root Cause Failure Analysis program, and during the program students analyze failures occurring in their products.Clients recover their training investment prior to course completion as these failures are eliminated.

This helicopter blade experienced a 50% rejection rate and a short service life. Root Cause Failure Analysis techniques identified inadequate bondline width as the underlying cause. Tightened tolerances and tool control increased the yield to 100%.
