What is it?
The Fishbone diagram (sometimes called the Ishikawa diagram)is used to identify and list all the factors that are conditioning the problem at hand. This is primarily a group problem analysis technique, but can be used by individuals as well. The process is called Fishbone Analysis because of the way in which the information gathered is arranged visually – like the skeleton of a fish.
This technique helps teams to understand the scope and scale of a challenging situation. It captures and collates all the different perspectives in the room that relate to the issue at hand. Hence it is ideal when the change team comprises people from different backgrounds or professional disciplines. Everyone is then able to bring their perspective into focus and the team is better informed on what is involved.
Identify the key factors first
Write down the problem on the right-hand side of a brown paper. Draw a straight line to the left (like the backbone of a fish). Draw stems at a 45° angle to the backbone line. At the end of each of these stems, list 5 – 6 key factors/headings of the problem or issue that can be brainstormed.
Analyse each of the key factors (main bones) in turn

Each of the key factors can then be broken down into subsidiary factors that need to be understood before moving on to solutions in the development phase. The team should been couraged to brainstorm each main ‘bone of the fish’ in turn. Perhaps each member of the team can take responsibility for facilitating the brainstorming of one main bone. That way it becomes a team-building exercise also.Source:
