Initially developed by Motorola (and current Motorolas registered service mark and trademark), the Six Sigma is a business management strategy. It is widely adopted in todays many industries. By using various management methods such as statistical methods, the Six Sigma tries find and delete any defects or errors during the manufacturing and business process. The strategy is also responsible for training a group of quality management method experts. Similar to some other business management methods, the Six Sigma project teams always have a specific plan with milestones along with a clear financial target.
