Presentation fish bone Diagram
- 1. FISHBONE DIAGRAM(Cause & Effect Diagram) INTRODUCTION: WHEN YOU HAVE A SERIOUS PROBLEM, IT'S IMPORTANT TO EXPLORE ALL OF THE THINGS THAT COULD CAUSE IT, BEFORE YOU START TO THINK ABOUT A SOLUTION. A FISHBONE DIAGRAM, ALSO CALLED A CAUSE AND EFFECT DIAGRAM OR ISHIKAWA DIAGRAM.
- 2. IT IS A VISUALIZATION TOOL FOR CATEGORIZING THE POTENTIAL CAUSES OF A PROBLEM IN ORDER TO IDENTIFY ITS ROOT CAUSES. A FISHBONE DIAGRAM IS USEFUL IN BRAINSTORMING SESSIONS TO FOCUS CONVERSATION.
- 3. ONE CAN USED IT FOR • DISCOVER THE ROOT CAUSE OF A PROBLEM • UNCOVER BOTTLENECKS IN YOUR PROCESSES. • IDENTIFY WHERE AND WHY A PROCESS ISN'T WORKING
- 4. STRUCTURE • THE DESIGN OF THE DIAGRAM LOOKS MUCH LIKE A SKELETON OF A FISH. • FISHBONE DIAGRAMS ARE TYPICALLY WORKED RIGHT TO LEFT, WITH EACH LARGE OF THE FISH BRANCHING OUT TO INCLUDE SMALLER BONES CONTAINING MORE DETAIL.
- 5. Fishbone diagrams are used in the "analyze" phase of Six Sigma’s DMAIC (define, measure, analyze, improve, control) approach to problem solving.
- 6. 4 Reason to use Fish Bone Diagram 1) DISPLAY RELATIONSHIP 2) SHOW ALL CAUSES SIMULTANEOUSLY 3) FACILITATE BRAINSTORMING 4) HELP MAINTAIN TEAM FOCUS
- 7. HOW TO USE THE TOOL STEP 1: IDENTIFY THE PROBLEM FIRST, WRITE DOWN THE EXACT PROBLEM YOU FACE. WHERE APPROPRIATE, IDENTIFY WHO IS INVOLVED, WHAT THE PROBLEM IS, AND WHEN AND WHERE IT OCCURS. THEN, WRITE THE PROBLEM A BOX ON THE LEFT-HAND SIDE OF A LARGE SHEET OF PAPER, AND DRAW A LINE ACROSS THE HORIZONTALLY FROM THE BOX. THIS ARRANGEMENT, LOOKING LIKE THE HEAD AND SPINE OF A GIVES YOU SPACE TO DEVELOP IDEAS.
- 8. Step 2: Work Out the Major Factors Involved Next, identify the factors that may be part of the problem. These may be systems, equipment, materials, forces, people involved with the problem, and so on. Try to draw out as many of these as possible. As a starting point, you can use models such as 7S or the 4 Ps. Step 3: Identify Possible Causes Now, for each of the factors you considered in step 2, brainstorm possible causes of the problem that may related to the factor. Show these possible causes as shorter lines coming off the "bones" of the diagram. Where a cause is large complex, then it may be best to break it down into sub-causes. Show these as lines coming off each cause
- 9. STEP 4: ANALYZE YOUR DIAGRAM BY THIS STAGE YOU SHOULD HAVE A DIAGRAM SHOWING ALL OF THE POSSIBLE CAUSES OF THE PROBLEM THAT YOU CAN THINK OF. DEPENDING ON THE COMPLEXITY AND IMPORTANCE OF THE PROBLEM, YOU CAN NOW THE MOST LIKELY CAUSES FURTHER. THIS MAY INVOLVE SETTING UP INVESTIGATIONS, CARRYING OUT SURVEYS, AND SO ON. THESE WILL BE DESIGNED TO TEST WHICH OF THESE POSSIBLE ACTUALLY CONTRIBUTING TO THE PROBLEM

- 11. TIP: A useful way to use this technique with a team is to write all of the possible causes of the problem down on sticky notes. You can then group similar ones together on the diagram. This approach is sometimes called CEDAC (Cause and Effect Diagram with Additional Cards) and was developed by Dr. Ryuji Fukuda, a Japanese expert on continuous improvement.
