What Makes Six Sigma The Best Quality Management Concept

May 16, 2008
DMAIC, short for Define, Measure, Analyze, Implement, and Control, is used for improving existing business processes whereas DMADV, short for Define, Measure, Analyze, Design and Verify, is used for designing and developing completely new products or services from scratch.

Both of these are recognized as the finest quality management concept ever devised.

So - What Makes Six Sigma So Effective?

Well, there are many reasons for that and you can identify a few just by going through the history of Six Sigma. You see, it was the Motorola Company that devised Six Sigma and used it for the first time in the seventies. The entire initiative proved to be a grand success and enabled the company to save millions of dollars.

If you look at this as a case study, you will realize that the success of Six Sigma was mainly due it's comprehensive and structured approach towards quality improvement initiatives. You will also realize that Six Sigma had made the best possible use of available organizational resources, something that enabled Motorola to achieve the desired objectives.

Other Reasons That You Need To Know

Six Sigma's effectiveness can also be traced to its inherent nature that lays stress on following a data driven approach. Following this approach helps a lot because it basically eliminates the chances of human errors that might occur during the implementation phase. Since all decisions are based on statistical tests and analysis, it greatly increases the probability that the quality improvement initiatives will be able to achieve the desired results.

It also makes it easier for implementation team members to understand the real meaning and purpose behind the proposed quality improvement initiatives.

Another reason is that in spite of following a data driven approach, Six Sigma does not fail to give due consideration to the human factor, without which even the best quality management concept will fail to achieve the set targets. During implementations, Six Sigma lays stress on change management, which helps businesses to provide the right motivation, support and guidance to organizational members. This in turn ensures that the employees will not falter while dealing with new challenges and responsibilities that might come up during the implementations.
So how effective Six Sigma really is?

Well, for that you just need to have a look at some of the dramatic results obtained through Six Sigma implementations. Six Sigma aims at achieving near-perfect businesses processes and this has been achieved by many businesses over the past few decades. Many businesses that implemented Six Sigma were able to lower their defect rate to no more than 3.4 defects per million opportunities that might have existed for such defects to occur.

This is quite enough for proving the effectiveness of Six Sigma. However, if you are still not convinced, just have a look at the ensuing benefits that come in the form of increased customer satisfaction, sales, and profitability. You will then know exactly why Six Sigma is the best quality management concept.
