Before you can go through Six Sigma Green Belt Certification, you need to know the basic concepts. Six Sigma strives to eliminate defects in any process or procedure by applying statistical analysis and statistical computing power. Once your company implement Six Sigma, it will have to submit its methodology or procedure to an independent party for approval. These approval procedures and Green Belt certification examinations to ensure that the Six Sigma methodology that your company uses meets the satisfaction of the customer requirements.
When you take your Six Sigma Green Belt Certification, you will need to know what a DMAIC (Define Phase, Measure, Analyze, Improve, Control) process is. A DMAIC process is made up of four phases. These are Analysis, Design, Measurement and Control. A Design phase defines the look and feel of your product or service. It focuses on conceptualizing and analyzing the customer needs.
Analyze is the next phase where you will work on analyzing the data that came from the Design phase. You may have to assemble data into a meaningful data set that you can use in your subsequent stages such as analysis and control. With data analysis, you can identify strengths and weaknesses in your project charter or your business processes. You also get to establish what the root cause of the problems is, and you can work on these areas with your six sigma training.
After that, it is important to know how the six sigma tools work. The first tool is the t-test, which is defined by the definition given in the first sentence of the six sigma definition. This t-test is used to show the weaknesses in the specifications of the product as well as show the crucial relationships among the weak parts.
The third tool is the continuous improvement approach. Continuous improvement focuses on making small improvements in the process over time. This way, over time, the system becomes more efficient. For continuous improvement to be effective, the product quality should be closely monitored based on the continuous improvement approach. This enables you to make small changes in the process, which is made could result in new benefits, and hence better customer satisfaction.
Another important tool in the six sigma green belt certification is the kaizen function. The kaizen tool is used to reduce the variability of the overall process. The kaizen function improves the process variability by removing the non-linearly dependent components, thus increasing the linearly dependent components. The improvement is possible because the process variations are dependent on the total output of the business, which will dictate the improvement of the overall equipment effectiveness.
The final six sigma method involves the use of two types of control charts: the ishikawa diagram and the matrix diagram. The ishikawa diagram shows the process flow in the process cycle, while the matrix diagram helps identify the problems associated with each process step. The main advantage of using the ishikawa diagram is that it is easier to understand. On the other hand, the matrix diagrams may require additional training, which is why most training providers include a third type of chart in the six sigma curriculum.
