A highly structured approach for eliminating defects in any process, whether from manufacturing or transactional processes. It can be applied to a product or a service-oriented process in any organization. Further, six sigma is a statistical term that measures how far a given process deviates from perfection. The goal of the six sigma is to systematically measure and eliminate defects in a process, aiming for a level of fewer than 3.4 defects per million instances, or “opportunities.”
