CRE Handbook

An ASQ Certified Reliability Engineer is the person who makes sure a product keeps working after it ships: predicting how it will fail, designing the failure out, and proving the result with data. Become one if you already carry that responsibility at work and can show the eight years of experience ASQ asks for.

That short answer hides a longer decision. The CRE is one of ASQ's harder credentials, it costs real money, and the application is judged before you are allowed anywhere near the exam. This guide sets out what the job involves, who the certification genuinely suits, what ASQ requires, what the current Body of Knowledge contains, and how to prepare for a 258-minute open-book exam without wasting a testing window.

What is a reliability engineer responsible for, and where do they work?

Quality engineering asks whether a unit conforms today. Reliability engineering asks how long it will keep conforming, under what conditions, and what happens when it stops. That single shift, from conformance to time, is what separates the two disciplines and it explains almost everything about the CRE exam.
