A three sigma process produces defects per million opportunities to make one. 233 3.4 308,537 66,807 Your Six Sigma team performed a hypothesis test on a proposed process vs. the old process to determine if the proposed process defect rate is lower than it was under the old process. You failed to reject the null hypothesis. What should your team do next?

Present your recommendation to management for permission to implement the proposed changes. Conduct a cost-benefit analysis to determine if the recommended process makes sense financially.
