A correlation diagram is a diagram that uses arrows to logically connect the causal relationships between elements based on the cause-result or purpose-means relationship to clarify complex and intertwined problems and organize language and written materials.

Correlation diagrams are suitable for analyzing and sorting out problems where various complex factors are intertwined.

After many revisions and drawings, the key to solving the problem can be clarified and the key points can be accurately grasped.

The questions clearly analyzed are circled with graphics.

Organize relevant personnel to fully discuss the problem and propose relevant factors that lead to the problem.

Name the factors causing the problem in clear language

Identify cause-and-effect relationships between problems and factors

Organize graphics to minimize or eliminate cross arrows

Find and identify important causes

Develop various management plans

Develop various policies and goals

Develop various improvement measures

Analyze various reasons

Improve the daily management activities of the enterprise

A system diagram is to systematically develop the goals to be achieved and the measures or means that need to be taken, and draw them into a diagram to clarify the focus of the problem and find the best means or measures.

In the process of planning and decision-making, in order to achieve a certain goal, it is necessary to select and consider a certain means; and in order to adopt this means, it is necessary to consider its corresponding means at the next level.

The upper level means becomes the action purpose of the lower level means.

By unfolding the goals and means required in order until measures can be taken, and drawing them into a tree diagram, you can have a comprehensive understanding of the problem, and then find out the key points of the problem from the diagram and propose solutions. The best way to set goals

Factor expansion tree diagram (component factor expansion diagram): systematically expand the factors that constitute the system object

Measure expansion tree diagram (method expansion tree diagram): Systematically expand the means and measures to solve problems or achieve goals and objectives.

The development of design quality in the new product development process

Develop a quality assurance plan and carry out quality assurance activities

Used in conjunction with cause and effect diagrams

Development of goals, policies, and implementation matters

Clarify departmental and management functions

Develop creative ideas to solve corporate problems related to quality, cost, delivery time, etc.

The process decision-making process diagram method is that when conducting quality management activities, in order to achieve goals or solve problems, always design plans in advance, predict possible problems and corresponding countermeasures or procedures, so as to lead things to the ideal results.

The process decision-making process diagram method refers to a method that predicts possible obstacles and results when formulating an action plan or designing a program in order to complete a task or achieve a certain goal, and propose multiple contingency plans accordingly.

Using the process decision-making program diagram method, the system status can be grasped from an overall perspective to make overall judgments, and the progress of the system can be grasped in chronological order.

Determine the topic and convene relevant personnel to discuss the topic

Determine the means and measures to achieve the goals from the discussion

For the identified measures, list the predicted results and the measures and plans to be taken when encountering difficulties.

According to each research measure, determine the order of implementation of each measure according to the urgency, required work hours, possibility and difficulty of implementation, and use arrows to connect the ideal state directions.

Identify the person responsible for the implementation and the implementation deadline

During the implementation process, collect information and continuously revise the process decision-making procedure chart

Develop implementation plans in policy and objective management

Develop implementation plans for research and development projects

Predict major accidents across the entire system

Formulate measures to prevent adverse factors from occurring in the process

Network diagram is a scientific management method to arrange and prepare the best daily plan and effectively implement progress management.

A network diagram is a "vector diagram" that expresses the various tasks necessary to advance the plan in chronological order and subordinate relationships in the form of a network.

A task or project can be decomposed into many operations. These operations are interdependent and restrictive in terms of production technology and production organization. The network diagram can clearly show this dependence and restriction relationship between various operations.

Through the network diagram, we can find out the key and non-key factors that affect the progress of the project. Myolie can make overall coordination and rationally utilize resources to improve effectiveness and efficiency.

The matrix diagram method is a method that uses pluralistic thinking to gradually clarify the problem.

The matrix diagram method is to find pairs of quality factors in complex quality problems, arrange them in rows and columns, and indicate the degree of their relationship at their intersections. Based on this, we can find out what problems exist and the form of the problems, and then find solutions. The idea of ​​​​the question

By giving the relationship and degree of the corresponding elements of rows and columns at the intersection, we can explore the problems and forms in the binary arrangement, and get the focus of solving the problem from the binary relationship.

When looking for solutions to problems, if the purpose (result) can be expanded into a unitary means (cause), the tree diagram method can be used

If there are more than two purposes (results), it is more appropriate to use the matrix diagram method to expand them

Determine the relationship between product quality characteristics and responsible departments

Investigate the causes of poor product implementation processes

Understand the correlation analysis between market and products, and formulate market development strategic plans

The affinity diagram method is a method pioneered by Jiro Kawakita of Japan.

Affinity diagramming is to focus on a certain problem, fully collect various language and written data such as experience, knowledge, ideas and opinions, summarize and organize these data according to their mutual affinities, clarify the problem from the complex phenomenon, and then solve the problem. question

Affinity diagrams are close to association diagrams, but association diagrams use logical reasoning to clarify cause-and-effect relationships, while affinity diagrams are classified based on rationality.

Determine the topic: Choose those things that are out of order or thoughts that are in a state of chaos as research topics

Collect audio and text data

Language data in cards

Organize comprehensive cards

The KT method is a thinking system that clearly distinguishes situations where problems occur and situations where problems do not occur based on the respective procedures of things, according to time, place, etc., and thereby finds out the reasons and the methods that should be decided.

The KT decision-making method is the most famous decision-making model. It was researched and invented by Americans Kepner and Trego, which divides the problem into two steps: defining the problem and analyzing the cause.

Prepare a decision statement with a plan of action and consequences of the action

Confirm strategic needs (requirements), action goals (expectations), and constraints (limitations)

Each project is assigned a weight and sorted one by one.

generate alternatives

Score options on an objective basis

Calculate the weighted scores of each option and find the top two or top three options with the highest scores

Identify the negative impacts of these high-scoring options and assess the likelihood and severity of these impacts

Based on the above evaluation results, make the final and only choice from these high-scoring options.

KT method can provide unbiased decision analysis

As a structured decision-making method, it identifies and sorts the various factors related to decision-making one by one.

As a past tool, the value of the KT decision-making method lies in its ability to effectively limit intentional or unintentional biases that can mislead decisions.

Users of the KT decision-making method can evaluate options based on clear objectives to optimize the final decision result.
