What are the seven techniques of quality management?

1, association diagram (Relationship Diagram)

Relationship Diagram, also known as Relationship Diagram, the 1960s by the Japanese University of Keio Chisumi Jinxiong Professor, is used to analyze the things between the "cause and effect", "purpose and means" and other complex relationships between a chart, which can help people from the logical relationship between things to find solutions. It is a chart used to analyze the complex relationship between things, such as "cause and effect", "purpose and means", etc. It can help people find solutions to problems from the logical relationship between things.

2, Affinity Diagram (Affinity Diagram)

Affinity Diagram method, also known as the KJ method, is the first Japanese Kawakita Jiro, a large number of collected on the unknown or unclear facts of the opinions or ideas and other linguistic information, according to their mutual affinity (similarity) to summarize and organize the information, so that the problem is clear, and seek to unify the understanding and coordination of work, in order to facilitate problem solving In order to facilitate the solution of the problem of a method.

3, System Diagram (System Diagram)

System Diagram is the purpose to be achieved with the need to take measures or means, systematically developed and drawn into a map to clarify the focus of the problem, looking for the best means or measures of a method.

4, Process Decision Program Chart (PDPC)

Process Decision Program Chart, also known as PDPC (Process Decision Program Chart) method is with the progress of the state of affairs to analyze the elements that can lead to a variety of results, and to determine an optimal process to achieve the desired results.

5, Matrix Diagram (Matrix Diagram)

Matrix Diagram method is a multi-dimensional problem from the event, to find pairs of factors, arranged into a matrix, and then analyze the problem based on the matrix to determine the key points of the method, it is a good way to explore the problem through the multi-factor integrated thinking.

6, Matrix Data Analysis (Matrix Data Analysis Chart)

Matrix Data Analysis is the analysis of multiple changes and complex cause and effect. If the relationship between the elements of the matrix can be quantitatively expressed in data, it can be more accurately organize and analyze the results. This type of matrix diagramming, which can be represented by data, is called matrix data analysis. Among the seven new tools of QC, matrix data analysis is the only method that uses data to analyze problems, but the results are still represented graphically.

7, Arrow Diagram (Arrow Diagram)

Arrow Diagram method is the implementation of the project will require the steps, operations according to the relationship between the network diagrams expressed in a method.

Extended Information

Origin

Both the old and new seven tools were summarized by the Japanese. After the success of the old seven tools, the Japanese came up with the new seven tools in 1979. The reason why it is called "seven tools", because the ancient Japanese samurai in battle, often carry seven weapons, the so-called seven tools is the seven weapons used.

There are, of course, more than seven useful tools for managing quality statistics. In addition to the old and new seven tools, commonly used tools include experimental designs, distribution maps, and pushover plots.

In fact, the methods of quality management can be divided into two main categories: the first is the organizational quality management based on the idea of total quality management; the second is the quality control based on mathematical and statistical methods.

Main content

Organizational quality management method refers to the method of quality management from the point of view of organizational structure, business processes and the way people work. It is based on the idea of total quality management, and its main contents are: formulating quality policy, establishing quality assurance system, carrying out QC group activities, sharing quality responsibility of each department, and conducting quality diagnosis.
