Gary Marion, writing for The balance, offers his insights on why Six Sigma is better than the idea of Seven Sigma. Check out my key takeaways from his article below.

- So minimizing defects by ‘six sigmas’ will uncover practically 100% of the defects in any given process
- Also, Six Sigma is a proven data-driven concept which can be demonstrated whereas ‘seven sigma’ is no more real than Hogwarts
