Interaction Between the House of Quality (within Design for Six Sigma) and the FMEA (within Design for Reliability)
The terms quality and reliability are often used interchangeably, but while they are strongly connected, they are not the same. While reliability is concerned with the performance of a product over its entire lifetime, quality is concerned with the performance of a product at one point in time, usually at the end of the manufacturing phase, to assure conformance to specifications. Reliability assures that components, equipment and systems function without failure for desired periods during their whole design life. One can say that reliability can be perceived as the continuation of quality over time. However, the underlying goal of quality and reliability systems is the same: to achieve customer satisfaction.

Design for Six Sigma (DFSS) has been widely employed as the framework to ensure that an organizations quality objectives are met and Design for Reliability (DFR) is becoming increasingly accepted as the best practice approach for ensuring reliability within the design. The two processes are complementary and there are many correlations between the tools employed by each. In this article, we present a brief summary of a comprehensive Design for Reliability process and we explore the relationship between two tools that are employed in the early product definition stage: the House of Quality (HoQ), which is part of the Quality Function Deployment (QFD) techniques used in Design for Six Sigma and the FMEA, which is part of the Design for Reliability process.

Using OC Curves in Design of Reliability Tests
Operating Characteristic (OC) curves are powerful tools in the field of quality control, as they display the discriminatory power of a sampling plan. In this article, we explain the applications of OC curves in reliability engineering.
