I. Reliability Management
A. Strategic management
7. Customer needs assessment (Apply)
Use various feedback methods (e.g., quality function deployment (QFD), prototyping, beta testing) to determine customer needs in relation to reliability requirements for products and services.

Quick Quiz
1-5. Identify the best manner in which to set an overall reliability goal.
(A) Set numerical requirements for reliability and duration(s) in specific operating environments.
(B) Have upper management identify those responsible for achieving the desired reliability.
(C) Incorporate into a contract a design specification requiring a product to have a high reliability.
(D) Require that the reliability goal be expressed in terms of the mean time between failures.
(A) Set numerical requirements for reliability and duration(s) in specific operating environments.
Each of the response provide an element or approach to setting a reliability goal. The key words in this question are “best manner” and “set”. “Best manner” implies a rank ordering according to some general scope or capability. Here I think “set” is similar to “state” or “establish”.
(A) The correct response relies on three of the four elements of the definition of reliability. It is measureable and specific.
(B) Having management support is a definite plus, yet alone does not provide a means to state a goal.
(C) Contract language may create a binding reliability goal, yet when stated as “high reliability” is not specific.
(D) MTBF is a common measure of reliability yet alone does not include the duration nor environment for the item to operate.
1-141. Identify what QFD stands for in the context of reliability.
(A) Quantitative Functional Deployment
(B) Quality Function Deployment
(C) Qualification of Functional Design
(D) Quality Focused Design
(B) Quality Function Deployment
Quality Function Deployment (QFD) is a structured approach to define customer needs and requirements as specific engineering specifications. The process also includes cascading the requirements to the assembly process thus linking customer needs to design specifications to assembly and component requirements.
