Comparative study of DFSS in product and service innovation

摘要

Six sigma has proven itself as a major quality initiative in the last two decades. It is a philosophy which provides audsystematic approach to applying numerous tools in the framework of several quality improvement methodologies.udThe most widely used six sigma methodology is DMAIC, which is best suited for improving existing processes. Inudorder to build quality into the product or service, a proactive approach like Design for Six Sigma (DFSS) is required.udThis paper provides an overview of DFSS, product innovation, and service innovation. The emphasis is onudcomparing how DFSS is applied differently in product and service innovation. This paper contributes by analysingudthe existing literature on DFSS in product and service innovation. The major findings are that the DFSS approach inudservices and products can be differentiated along the following three dimensions: methodology, characteristics, andudtechnology.
