Design for Six Sigma
Design for Six Sigma (DFSS) is an essential approach that consists of a set of methodologies used in the product development process. DFSS is a vital tool that assists a company to ensure that the ultimate end-product meets the customers’ needs as portrayed through its high quality and by achieving its performance objectives. As an essential production tool, DFSS assists designers and engineers to better translate customer requirements into design concepts, concepts into detailed designs, and detailed designed into well manufactured goods or efficient services. DFSS is regarded as a vital aspect of production as this approach leads to reduced costs, better quality, and a better focus on the customer. DFSS is a methodology that ensures each work process is performed excellently in the defined manner. The DFSS methodology tool allows the organization to remove unnecessary steps with the primary interest of achieving quality results with reduced variations and minimal defects. A vast majority of companies seeking to produce standard, high quality goods and services have incorporated DFSS methodology tool as part of its operating procedures. Additionally, DFSS is a vital methodology tool that assists the company in its production operations so as to meet the customers’ needs whilst achieving the ultimate performance objectives. Through DFSS, a firm is able to measure the defects in its production processes so as to systematically come-up with key solutions to eliminate the production hitches.
From time immemorial, customers have always been the center of any business entity as they rate and define the quality standards of the products and services produced by the company. Customers need to feel the variance in transaction and each product sold. This can be achieved by reducing process variation and improving the process capability. Customers value consistent, predictable business processes that deliver high levels of quality.
DFSS consists of four critical aspects: concept development, detailed design, design optimization and design verification (Brue & Launsby, 2003). DFSS commences with the concept development which focuses on creating and developing a product idea that would match the customer’s needs, technological specificities and cost-friendliness. The concept development is later followed by the development of specific design parameters that will eventually fulfill the functional requirement of the concept. Design optimization is the third stage of DFSS as the engineers seek to identify and eliminate potential problems with the key intent of ensuring that the entire production process is smooth. The last stage of DFSS involves the verification of the designed product so as to ensure that the quality standards of the ultimate end product are at par with the company’s and customers’ expectations. Ultimately, the DFSS principal activities get incorporated DMADV process which stands for; define, measure, analyze, design and verify (Brue & Launsby, 2003).
