Lean Six Sigma Design In Products And Services-pay.91860.net

UnCategorized Organizations who have adopted Six Sigma have learned that if they do not design for Six Sigma, they will not achieve it. DFSS is a rigorous approach to designing products and services and their enabling processes to ensure that they meet customer expectations. As the organization evolves in Six Sigma, we will learn more about the importance of DFSS, and apply the tools more frequently. The classical or traditional approach to product/service and process design generally involves several functional departments working in series. This classical approach tends to lengthen the development process and increases the opportunities for defect at each step of the process. .munication between groups has little impact on the overall definition due to the serial nature of the process engineering, drawing rework is the accepted norm and as schedule pressures mount in manufacturing firefighters emerge as the heroes of the day. Each manufacturing challenge must then be quickly resolved with short-term fixes and root causes are either difficult to identify or expensive to fix at this point and are therefore not pursued. Design for Six Sigma (DFSS) on the other hand, is a parallel (concurrent) activity where all applicable disciplines are represented within a cross-functional team. There is a vast psychological difference between performing a task within a functional group performing it as a cross-functional team member. Furthermore, all relevant knowledge, information, and data is made available to the teams so that decisions are data based versus the traditional judgmental basis. Product service designs and manufacturing transactional processes can therefore, be developed together; meaning that the product and process can be made optimal relative to each other, resulting in fewer design changes, lower manufacturing cycle times, enhanced product quality and reliability, and reduced total cost. Although each of the DFSS tools can be applied to the design process in and of itself the true ‘"global"’ benefit can only be realized through an integrated application across the board. Knowledge of each applicable long-term process shift and drift is crucial to the selection of appropriate processes that meet the CT based design tolerance to a Six Sigma quality level. Utilization of reverse error propagation allows for driving down of system design specifications that are based on elemental capabilities making up the whole. Product and process .plexities have a direct effect on DPMOs. The more .plex the process or product is the larger the number of opportunities for defect will be. In fact the notion of manufacturability has product simplification as its cornerstone. Rigorous methods are used to drive down process steps, parts count, fastener count, special tooling, reorientation, forms, and so on. Simulation & DOE can be effectively used to identify leverage variables, establish sensitivities of the response variable, and define tolerances through the deliberate arrangement of .peting settings among one or more independent variables. The goal here is to provide the most efficient and economical means for arriving at valid and relevant conclusions and resulting in reduction of variation at minimal cost. About the Author: 相关的主题文章:
