Six Sigma is a good masurment for a upcoming product????????

certainly NO.six sigma comes into a picture when all common and technical methods fail to give a good product.if any one uses for brand upcomming, it will be as good as that product has been tried for so many common tests and it has failed and finally its entire process is corrected by this tool called six sigma.this tool should be for internal correction of process for defect free performance and sustainability / reducing wastage etc.,

As we all understand that six sigma is a quality measurement and improvement tool that helps reach & maintain the optimum level of quality. Now, when the product is not yet launched in the market, it becomes difficult to have the quality for the product mapped. To my opinion, this tool is not useful when the product is yet to be launched.

Well as we all understand Six Sigma is a quality measurement tool for reducing errors or in other terms to reach between +-3 deviations. Now can this be used for an upcoming product in the market; To my opinion, sigma can be calculated only when the product has been launched. In other words, we can apply six sigma techniques to bring the quality level to the optimum only the product is in market.

Sonal i agree with you and adding to what you said Six Sigma is a disciplined, data driven approach and methodology for eliminating defects (driving towards six standard deviations between the mean and the nearest specification limit) in any process -- from manufacturing to transactional and from product to service.To achieve Six Sigma, a process must not produce more than 3.4 defects per million opportunities. The fundamental objective of the Six Sigma methodology is the implementation of a measurement-based strategy that focuses on process improvement and variation reduction through the application of Six sigma improvement projects.

6 sigma is best for improving process. market survey, innovation & vision are best ways of introducing any new product.
