Six Sigma provides a structured, disciplined approach to improving processes and developing products, processes, services and software. The structured approach keeps the project on track, with expectations and deliverables, while providing a set of flexible, powerful tools and methods that lead to verifiable results – results that can be validated by financial experts. Six Sigma also involves a culture change – and, as with most culture changes, there is a story behind it. The story of Six Sigma involves a conscious decision to improve a company and its products and processes – and a decision to share Six Sigma with the rest of the world.
