Design robustness assessment-a technical overview

Abstract

Design robustness assessment (DRA) is a technique for quantifying the design robustness of electronics-based products through empirical testing. The DRA technique was developed and refined within IBM, and has been applied during the development phase of most IBM Personal System/2 products, including systems, options and peripherals. DRA has proven to be an effective technique for finding latent design problems and pinpointing areas that would benefit from application of robust design techniques. This paper provides a brief explanation of the DRA test process and explores the relationship between DRA results and design robustness.<>
