Six Sigma is equal to perfection
Okay. This is the first misunderstanding that forces a lot of business owners to consider Six Sigma as an approach. They are thinking that Six Sigma will create them perfect. Not actually! Using Six Sigma only companies will become perfect in meeting customer demands. The issue is customer requirements and expectations can vary as time varies. In such a situation, the operating system (flow) of the organization should be flexible to capture the modifications.
Six Sigma means removing variation
“A process without variation is not considered as a process.” quoted by Dr. William Edwards Deming. Considering Six Sigma as a method you are able to only decrease variation and not removing it. The way to decreasing variation is reducing it to an amount where the process holds in statistical control at all times. The predictable output is possible only when the process is in statistical control. When statistical control present with decreased variability, the objective of the Six Sigma method is as near to being achieved.

Six Sigma deal with normally distributed data
The general saying is, “If you want to travel from Place A to Place B, you are able to go by five different ways. Why are you so fixed of selecting Route A always then?” Many people have a serious preference, some type of attraction in selecting to work with normally distributed data. And is not incorrect because it is just so simple to work with such data! That said pleading and forcing your data to look normal when it is not forcing a horse to run miles without a guide! For the information — There are 40 various data distributions. So there are chances your process data could fall in any of type distributions and not essentially normal.
Six Sigma is nothing but DMAIC
I tell you if gossip is to be considered, DMAIC stands for Define Measure Analyze Improve and Control must be awarded the Cure-It-All title. DMAIC is a pet method for a lot of professionals when they want to enhance the performance of processes. But just to state that DMAIC is the only center point of Six Sigma is speaking something that is a bit far-away from the truth. For the information, you are able to use DMAIC only to advance present processes. Where you do not have a processor where you want to re-construct a process or re-arrange a process, you must be in a position to use Design for Six Sigma (DFSS).
It is a set of tools that creates Magic
This myth needs to be discussed in detail. Any professional trusts that Six Sigma just has to be begun and the rest will trail its course. Tools of Six Sigma are good and you should use the tools and the outputs will be delivered. The important thing here is to acknowledge that the application of tools just does twenty percent of the work. The tools can give only numbers to you. If you cannot create sense out of the numbers and usage of them for your business, possibilities of your failure in the maze are more. You are thinking of a higher probability for sure. And we also possess the unspoken strength of Brainstorming, a tool that is not immersed into the statistical scheme of things anywhere?

Measuring the data is Six Sigma
Importance on measuring data and the right type of data is taken care of by the true Six Sigma. But the significance of other stages like Define, Analyse, Improve, and Control should not be lost out on practitioners. For instance, the first stage i.e Define stage of a Six Sigma project is one that takes up the highest prominence in the scheme of things. If you do not mention and describe an issue well, the possibilities of going off the track will increase. By providing awareness about these myths, the advice I want to deliver is – It is not an approach which you would think of offering into the deliberations discussed in this article. Six Sigma is a statistical approach and it speaks a lot about validating and measuring data but sufficiently have to be completed on the ground to advance a process.
