The Reliability Green Belt®

5-day In-person Course

& Certification Program

This course is for engineers, technicians, specialists, and executives in the areas of product development, design, testing, production, quality, and management.

Reliability is important. It is a vital competitive factor in today's market.

Dependable products increase customer satisfaction and reduce warranty-related expenses.

A methodical planning and safeguarding of product reliability, availability, and service life are necessary to meet these challenges in the face of the complexity of today's systems.

The Reliability Green Belt® comprises the first of three modules in the qualification as a Reliability Engineer Master Black Belt®.

In this module, the most important qualitative and quantitative methods of reliability engineering are imparted. The Green Belt training is deliberately structured to teach the participant when, how and why the individual methods can be applied in the product development process. The essential reliability activities can thus be independently implemented and integrated in a company’s organization by its own employees.

  • What I especially enjoyed about the Reliability Green Belt Program was the technical discussions with the teacher and participants we had throughout the 5-Day class. Les was a really knowledgable trainer and his wide range of experience and examples from industry helped to apply the training material and get a better understanding of it. I would especially recommend this training for people that haven't been exposed to Reliability much yet. — Celine, Reliability Manager

  • Les, you were awesome. One of the characteristics I liked the most was your cadence of speech. The metered delivery of each word and concept was very effective for me and my style of learning. If the words and concepts get delivered too quickly, I don’t have enough time to connect with the concept, write down my notes, and still keep up with the next thing being said. I found your analogies and examples of real world applications to be very relevant and helpful. Overall, I feel I have received value well above my expectations for the course, and with your instruction I was able to hit the ground running on the first day I got back. Thanks for teaching the course, and I look forward to continuing my education with the Reliability Black Belt program. — Chris, Reliability Engineer
