![]() The cause-and-effect matrix is also called the X-Y diagram, Prioritization Matrix, and Correlation Matrix. It helps you identify, explore, and display all the possible causes and finally find the root cause of the problem. ![]() The diagram looks like a fish skeleton, hence the diagram's name. After listing all the variables, the expert team should determine which variables are most likely to be causing the problem. First, you start with the specific problem and list all the variables in their respective categories affecting the problem. It helps you define which variables you should study further. Finally, the designs with the highest scores will become the solution you should implement. Next, you list various design options based on their ability to address customer needs. ![]() It will help you identify customer requirements and rate them on a numerical scale. Here are some of the essential tools that almost every Six Sigma Model uses. To be able to do calculations, you need to incorporate the tools into Six Sigma software, which will do the rest of the job for you. To improve the quality of the DMAIC model, there are various tools, all of which can be divided into two categories: process optimization tools that allow you and your team to create more efficient workflows and statistical analysis tools that let you analyze data more efficiently. Naturally, most businesses operate at 4 or 5 Sigma, which means that the losses that result from poor quality cost them 10-15% of their revenue. The lower the sigma level, the bigger the number of defects. The Six Sigma scale shows how well an important feature performs compared to its requirements.
