Six Sigma Basics Are A Must See

Many production industries want to be the most competitive in their field. There is no better way to be competitive other than quality delivery. However, sufficient quality achievement is not ordinarily easy. The Motorola Company introduced a method to control quality in the 1980’s called Six Sigma; it was and still is the best method.

Six Sigma is a quality control method developed by the Motorola Company in the 1980s. It may sound complex and mathematical at first, and that is why it is important to start looking at the basics for a deeper understanding of its merits. It is more of a statistical process.  To start with, it should be understood that it is simply a method that aims at reducing the inefficiencies of any production process. It is basically a management philosophy used to reduce defects while making sure that customers are satisfied as well. The six sigma process involves understanding the processes and correcting any inadequacies.

Even if you don’t know what a sigma is or why 6 of them are significant, you can still understand the aims and goals of this technique. Six Sigma is just a level of efficient production that connotes a near perfect outcome of less than 3.4 defects per million opportunities (3.4 DMPO). There are several levels. For example one sigma level might mean a high inefficiency of about ten times less than three sigma level. Level six is the sweet spot for manufacturing, used as a goal for this quality improvement methodology. This is the closest to perfection a company can reach.

The actual Six Sigma process is a five step one, represented by the acronym DMAIC (Define, Measure, Analyze, Improve, and Control). It starts with the define step. This explains the goals of a project and customer deliverables. Step two is the measuring and quantifying the current performance. The other steps include the analysis of the performance, improvement of the level and finally controlling the future performance of the process.

The best practitioners of the Six Sigma Methodology (referred to as belts) are not easy to find. Neither is it easy for a company to train them, but it is a worthwhile endeavor. High level project leaders are referred to as Black Belts. Green Belts are the next in charge, and finally, Yellow Belts have the lowest level of Training and Certification.  Master Black Belts have additional training and are able and capable to train the other levels of Certification.

It is a serious misconception that only big companies with fat pockets are able to implement this Six Sigma strategy. This is wrong. Any company is able to improve the quality of their output with this statistically-driven, results-based process if all employees are committed to its success.
