Tips to Create Fishbone Diagram If you choose to draw on hand, consider drawing your fishbone diagram on a flip chart or large dry erase board. Same causes can be written in several places if they relate to several categories. Be clear about the major categories of causes of the problem (written as branches from the main arrow). Make full use of the fishbone diagram tool to help the team focused on the causes of the problem, rather than the symptoms. Brainstorm all the possible causes of the problem. Organize a team to carry out the undertaking rather than rely on your own. Created by Edraw - all-in-one diagram software

5W1H Method for Cause-effect Analysis 5W1H Method for Cause-effect Analysis Is there anything else to do? What should be done? What What should be improved? What is the purpose of improvement.
