DOLLAR COST The fishbone diagram or cause and effect diagram identifies many possible causes for an effect or problem. It can be used to structure a brainstorming session. It immediately sorts ideas into useful categories. Materials needed: flipchart or whiteboard, marking pens. Methods Machines (equipment) People (manpower) Materials Measurement Environment Write the categories of causes as branches from the main arrow. Brainstorm all the possible causes of the problem. Ask: “Why does this happen?” Write sub–causes branching off the causes. And generate deeper levels of causes indicate causal relationships. Focus attention to places on the chart where ideas are few.

Write it at the center right of the flipchart or whiteboard. Draw a box around it and draw a horizontal arrow running to it. Brainstorm the major categories of causes of the problem. If this is difficult use generic headings: Is useful to analyze process dispersion with this simple, visual tool. The resulting diagram illustrates the main causes and subcauses leading to an effect
Transcript: What it looks like Fishbone Diagram Classic fishbone diagram Analyze your diagram. By this stage you should have a diagram showing all the possible causes of your delay / problem. Depending on the complexity and importance of the problem, you can now investigate the most likely causes further. This may involve setting up interviews (see getting patient perspectives), carrying out process mapping or surveys which you can use to decide whether the causes identified are correct. Take each of the main categories and brainstorm possible causes of the problem. Then, explore each one to identify more specific 'causes of causes'. Continue branching off until every possible cause has been identified. Where a cause is complex, you might break it down into sub-causes. Show these as lines coming off each cause line. Patient Re-admission Process-type cause and effect diagram Firstly, identify the problem. Write it in a box and draw an arrow pointing towards it. Think about the exact problem in detail. Where appropriate, identify who is involved, what the problem is, and when and where it occurs. CONTD.... A cause and effect diagram, also known as an Ishikawa, and it is a graphic tool used to explore and display the possible causes of a certain effect. It helps to identify areas for improvement. When causes group naturally under the categories of Materials, Methods, Equipment, Environment, and People Classic Diagram FISHBONE DIAGRAM Visually explanation To show causes of problems at each step in the process. It graphically displays the relationship of the causes to the effect and to each other. When you need help fully understanding an issue and to identify all the possible causes - not just the obvious. If you know the cause of the delay, you are then better placed to implement the solution. Variety of benefits Teach-a-tool It helps teams understand that there are many causes that contribute to an effect Solutions Identify the major factors and draw four or more branches off the large arrow to represent main categories of potential causes. Categories could include: equipment, environment, procedures, and people. Make sure that the categories you use are relevant to your particular problem / delay. When is it used Application to the real world How is it created? Process-type cause and effect diagram Creates a clear understanding

Created by Kaoru Ishiawa in 1968 The diagram shows the causes of a specific event Causes are usually grouped into major categories to identify sources of variation Then factors causing the overall effect are found Game plan Step by Step Product Design Quality Defect Prevention Situations Marketing Industry Eat Healthy Car Fishbone Diagram Swim trunks Ideal Situations By: Joel Jackson & Joe Pedrotty College Friends Sun screen Ask Parents Supplies Needed The fishbone diagram captures the associations and relationships among the potential causes and effects displayed in the diagram Any cause or causal chain featured on the fishbone diagram could be contributing to the problem. The fishbone diagram is a great way to stimulate and structure brainstorming about the causes of the problem The fishbone framework can keep your team focused as you discuss what data needs to be gathered Going on Spring Break Safety Do it ahead of time

Transcript: Time for an Activity! This would be a great to use in the elementary classrooms and with higher grades. It would help give the students a deeper understanding of the problem, because it gives several causes. How do you Create a Fishbone? Ideas Take 5 minutes to think about the following topic: What causes students to loose their recess? Fishbone Diagram Notes Create a head, which lists the problem or issue to be studied. Create a backbone for the fish (straight line which leads to the head). Identify at least four “causes” that contribute to the problem. Connect these four causes with arrows to the spine. These will create the first bones of the fish. Brainstorm around each “cause” to document those things that contributed to the cause. Use the 5 Whys or another questioning process such as the 4P’s (Policies, Procedures, People and Plant) to keep the conversation focused. Continue breaking down each cause until the root causes have been identified. Ideas a visualization tool for categorizing the potential causes of a problem in order to identify its root causes. Work Cited Definition This diagram is useful in brainstorming sessions to focus conversation. It is easier to follow other peoples train of thought. http://whatis.techtarget.com/definition/fishbone-diagram Why Should We Use It? Ideas How do we use this?

Hard to break down complex problems No cross-linked cause-effect relationships represented Interactions and temporal dependencies are not covered Few thick clusters & specific causes may need further studies Step 3: Identify Possible Causes Good basis for discussion Easy to learn and apply Promoting a better understanding of problems Focus on the 'bigger' picture Thoughtful analysis without overlooking root causes Increases process knowledge 1915 - 1989 in Japan 1943 first introduction of the Fishbone diagram quality manager for Nissan (1941-1947) 1962 first introduction of the Quality Circles ?
