Traditional Quality and Reliability Engineering often are separated, which cause lacks powerful methods and tools on the earlier development stage and takes high cost and long time. This paper proposes a new integrated quality and reliability methodology based on Life Cycle Six Sigma (LCSS) to assure product good quality, high reliability, low LCC, low price and short lead time simultaneously. A set of integrating methods and processes such as Q&R management, DOE, parameter design and tolerance design for product detailed design and optimization, HALT, HASS, SPC, CPK and Signal to Noise Ratio for product verification and manufacturing, Generalized FRACAS and eight Low-Cost Reliability Growth approaches are developed in this paper. Case studies suggest that these advanced process and technical methods will promote improvement and development of traditional reliability engineering to raise product core competitive power.

This study aims to solve one of the difficult problems about Six Sigma critical techniques that is how to design tolerance based on Life Cycle Six Sigma(LCSS) and concurrent quality engineering. The objective is to improve design quality and reduce cost in the up-front phase of the development cycle. Robust and optimizing methods on the basis of LCSS Methodology are used as the technical foundation of six sigma tolerance design. In this paper, concurrent parameter and tolerance design models are integrated into LCSS methodology to realize the objectives of product robust design and process robust design within life cycle process, in terms of high quality and lower life cycle total cost.
