How does a company determine whether six sigma is right for them? The authors explains that six sigma is a company cultural change. Case studies indicate the change can be profitable but requires tremendous commitment, resources, and time to implement effectively. The authors assess readiness with three questions: 1. Is change a critical business need now 2. Can the company come up with a strong rationale for applying six sigma to their business 3. Will the existing improving systems be capable of achieving the change needed.
