We will support the establishment of your company's seven QC tools!
In the manufacturing industry, there are seven tools of QC (Quality Control) used for education and guidance. These tools are primarily utilized on the production floor to confirm quality and identify opportunities for quality improvement, and they are employed by analyzing numerical data such as statistical information. The seven tools are: 1. Pareto chart, 2. Histogram, 3. Control chart, 4. Scatter diagram, 5. Cause-and-effect diagram, 6. Check sheet, 7. Graph. We support the basic usage, application, and establishment of these tools.

basic information
Here is the explanation of these seven tools: 1. Pareto Chart For example, it is used to compare the number of defects by item in a bar graph to suggest the priority of defect countermeasures. 2. Histogram It represents the frequency of a certain event divided into specific ranges, generally depicting a normal distribution. 3. Control Chart This tool is used to check whether the quality of products in each process is stable, evaluated through a plotted chart based on sampling checks, and is used for daily management. 4. Scatter Plot This is a plot of data points corresponding to two variables on the vertical and horizontal axes. 5. Cause-and-Effect Diagram Also known as a fishbone chart, it is a method for analyzing the causes of events such as defects, categorizing them into 5Ms and 1E, and depicting the causes like fish bones. 6. Check Sheet This is used to collect data easily in an organized manner, utilizing a form with spaces and item names to investigate where and how much occurrences happen. 7. Graph These are charts created to visualize information that cannot be understood through numbers alone, making it easier to comprehend. That is all.
