The benefits of a free Six Sigma Black Belt SPC test

 For any manager working in the business environment the term „Six Sigma” should sound at least familiar. Although it is a relatively recent concept, the Six Sigma has gained appreciation for providing the systems and tools to solve problems in a professional and methodical manner. The Six Sigma is an innovative managerial concept firstly developed by the Motorola American company in 1986. This method aimed to reduce errors and to help making things better and faster through a set of quality standards for daily work. Six Sigma originated as a set of practices designed to improve manufacturing processes and eliminate defects, but its application was subsequently extended.

The Six Sigma approach has a very well-defined structure known as the DMAIC project methodology. This business management strategy creates a special infrastructure of people within each company who are experts in the above-mentioned methods. The training for Six Sigma is provided through the belt based training system. The Black Belts follow after the Master Black Belts who are on top of the hierarchy and are very reputed professionals in this field. They must have a complete understanding of all the insights of the DMAIC model according to the principles of Six Sigma and SPC is a very important step of the Control phase of a process. SPC stands for Statistical Process Control and involves applying specific statistical methods for monitoring and controlling a process. The purpose of this activity is to make sure the process is completely operable and efficient in terms of producing the desired outcomes. SPC found applicability mostly in manufacturing industries and it was used for predicting a process capacity of producing quality products that meet specifications and reducing wastes. However, its application has been subsequently extended to control any process with a measurable output.

The main benefit of the statistical process control is guiding us to what types of actions should be taken to improve the functioning of a process. It should either guide us to react to individual results of the process or to change the entire process for reaching the desired output. Whether the process is in or out of control, there are many occurrences happening at every phase. But the question is whether such occurrences mean something important and should worry us or not. When the process is in control, the answer would be no, but if the process goes out of control then yes, we should pay attention to the variations and take the appropriate measures for driving the process in control again.

SPC uses various tools to perform an objective analysis for the early detection and prevention of problems that may arise. By doing so, it can also reduce the necessary time to produce the expected output, thus making SPC a valuable tool for cost reduction and customer satisfaction. The most important diagnostic tools used in the SPC are control charts that are meant to identify any special causes that may affect the good progress of a process. Control charts are very useful for recording data and for making the distinction between common cause variations of a process that are always present and special cause variations that indicate the process is out of control. The latter variations will require different actions to be taken depending on theie effects on the process. If they have a negative effect measures must be taken to eliminate those causes, whilst if they have beneficial effects they should be made standard operating procedures. After such actions will be taken you should be able to direct your efforts towards improving the process and making sure these improvements are maintained. For achieving this you should be able to use other statistical tools, such as different flow-charts, Ishikawa diagrams, Pareto analysis and so on.All this being considered, SPC is a very important step in the development of a process and if you want to become a Six Sigma Black Belt you need to make sure you have the proper knowledge and skills related to this topic.
