Design for Reliability
Design Processes
Designing products for consistent performance over time.
In practice
In product development, Design for Reliability focuses on ensuring that products consistently perform according to specifications over their lifecycle. By incorporating reliability principles into the design phase, designers aim to identify and address potential failure modes, optimize components for durability, and enhance overall product dependability. Design for Reliability contributes to customer satisfaction, reduces warranty costs, and establishes trust in the reliability of the designed products.
Questions
What is Design for Reliability?
Design for reliability is designing a product to keep working for its intended life under the conditions it will actually meet.
Why do you use Design for Reliability?
Reliability failures are expensive twice: once in warranty and again in reputation. They are also almost always designed in rather than manufactured in.
How do you use/apply Design for Reliability?
Identify the stresses and failure mechanisms, design margin against each, and test to failure rather than only to specification.
When do you use Design for Reliability?
During detailed design, verified through accelerated life testing.
Who uses Design for Reliability?
Design and reliability engineers.
