Cause and Effect Diagrams - Problem Solving Tool

Cause and effect diagrams were developed in 1943 by the University of Tokyo's Kouro Ishikawa. Cause-effect diagrams or fish bones are use to list many and various causes that may be attribute to the problem. These diagrams can help identify the reasons why the anticipate or not expect causes.

Cause and Effect Diagrams help you get completely through the causes of the problem. The cause and effect diagram is also known as fish bone diagram, because the complete figure looks like a fish skeleton.

How to use the tool?

Follow these steps to solve the problem of cause and effect diagram:

Identify the problem:

Write a specific problem you can understand. Identifies who is involve, what is the problem, and when and where it happens. Write a problem in the left-hand box of a large sheet of paper. Draw a horizontal line from the box. This arrangement, which looks like the mask's head and spinal cord, gives you space to develop ideas.

Work for the main factors involve

Then identify the factors that can contribute to the problem. Draw spinal lines for each factor and label it. These can be people involve with problems, systems, equipment, materials, external forces, etc. Try to remove as many possible factors as possible. If you are trying to solve the problem as part of the group, then this may be a good time for some mental development. By using the 'Fish Bone' similarity, the factors you are looking for can be thought of as fish bones.

Identify the possible causes

For each of the factors consider in phase 2, consider the possible causes of the problem that may be related to the factor. Show these small lines from the 'bones' of the fish. Where no reason is big or complex, it may be best to break it into sub-reasons. Show this as the lines coming from each line line.

Analyze your diagram

At this point you should have a diagram showing all the possible causes of your problem that you can think of. Depending on the complexity of the problem and the importance, you can now investigate more potential causes. This can include checking, conducting surveys, and so on. This assessment will be done to verify whether your assessments are correct.

Strengths & Weakness

Strict analysis which hates a potential problem source. The easy-to-understand understanding of the reasons, categories of causes and the problem presentation of the problem statement

The simplicity of the fishbone diagram can be both its strength and its weakness. As a vulnerability, the ease of fishbone diagram makes it difficult to present a true inner-relate nature of problems and to present reasons in some very critical situations.
