In recent decades, with the development of computer and Internet technology, the worldhas entered the era of the rapid development of digital information. Since HDD meets thepeople’s needs for data and information storage, HDD hasbecame the backbone of the storagemedium and has been widely used in computer, network server, monitoring equipment, camera,TV, on-board video and so on. However, in recent years, SSD solid state drive with its lightweight, small size, low power consumption and environmental adaptability, etc., graduallyreplacing the HDD drives in portable electronics application field. With the development ofSSD storage technology, SSD will further erode the traditional HDD market.S company is the world’s largest independent manufacturer of HDD read-write head,which supply headsfor all theHDD manufacturers in the world. There were more than twohundreds of HDD manufacturers, after decades of survival of the fittest, mergers andacquisitions, as of2011only remain WD, Seagate and Toshiba three.

In mid2013, the new product of S company900GBPSI head started mass production with only50%head yield and nearly doubleproduction cycle time compared to750GBPSI product. How to quickly improve theperformance and quality of new products, shorten production cycle and reduce the cost ofproduction, is the primary problem to be solved in S company.This paper aims to review and studyLean Six Sigma theory and its application experience,and apply the Lean Six Sigma on thequality improvement of900Gbpsi product, so astoprovide customers with high-quality and low-cost head products.This research projectapplied the lean-six-sigma theory&tools, project management knowledge and the otherrelated theory successfully, then improved the head performance to price ratio and maintaineda leading market share.
