Homework: Computer Science Fishbone Chart

Fishbone Charts/Diagrams (also known as Ishikawa diagrams, herringbone diagrams, or cause-and-effect diagrams) are causal diagrams created by Kaoru Ishikawa, a Japanese quality control expert that show the potential causes of a problem. Essentially, it is a visualization tool for categorizing the potential causes of a problem. "The value of using the fishbone diagram is to dig deeper, to go beyond the initial incident report, to better understand what in the organization's systems and processes are causing the problem, so they can be addressed".

"It is a more structured approach than some other tools available for brainstorming causes of a problem (e.g., the Five Whys tool). The problem or effect is displayed at the head or mouth of the fish. Possible contributing causes are listed on the smaller "bones" under various cause categories. A fishbone diagram can be helpful in identifying possible causes for a problem that might not otherwise be considered by directing the team to look at the categories and think of alternative causes. Include team members who have personal knowledge of the processes and systems involved in the problem or event to be investigated".

Fishbone Diagram Procedure

I. Agree on the problem statement (also referred to as the effect). This is written at the mouth of the "fish." Be as clear and specific as you can about the problem. Beware of defining the problem in terms of a solution (e.g., we need more of something).

II. Agree on the major categories of causes of the problem (written as branches from the main arrow). Major categories often include equipment or supply factors, environmental factors, rules/policy/procedure factors, and people/staff factors.

III. Brainstorm all the possible causes of the problem. Ask "Why does this happen?" As each idea is given, the facilitator writes the causal factor as a branch from the appropriate category (places it on the fishbone diagram). Causes can be written in several places if they relate to several categories.

IV. Again asks "Why does this happen?" about each cause. Write sub-causes branching off the cause branches.

V. Continues to ask "Why?" and generate deeper levels of causes and continue organizing them under related causes or categories. This will help you to identify and then address root causes to prevent future problems.

For this homework, identify a possible or actual problem in your organization. Note that having personal knowledge of the processes and systems involved in the problem to be investigated will help present a more realistic problem statement. Once you establish a problem statement, brainstorm to identify the possible causes of the problem. Using a fishbone diagram and the steps outlined above display the cause and effect of the identified problem. Finally, write a brief report on your diagram identifying the possible ramifications of the identified problem if unresolved soon.
