Fish Bone Diagram Practice

The Fishbone diagram was invented by Mr. Ishikawa, the master of Japanese management, and is called "Ishikawa map". The role of Fishbone diagram is to find the "root cause" of the problem, so Ishikawa is called the "cause and effect diagram."

Fishbone diagrams are similar to the MindManager tools we often use, and when we want to build a holistic understanding of a problem, we often take advantage of the ability of MindManager's powerful brainstorming to diffuse and analyze a problem point.

Compared with MindManager, Fishbone diagrams are more focused on analyzing the characteristics of the affected problems. We find the factors that lead to this problem through brainstorming, and we associate them with the attribute values, which are organized into a hierarchical, well-organized graph, in the form of Fishbone (Fishbone Diagram).

In the process of drawing MindManager and Fishbone diagram, we can't do without brainstorming. So what is brainstorming? Brainstorm should be around a specific problem, we can not digress, the conference initiator should provide a relaxed environment, the participants in the meeting to put forward a new point of view, and then put all the views of the people to record, and ultimately form a solution to the problem.
The practice of good brainstorming sessions
1) The sponsor of the conference will often send the topics of the meeting and relevant materials to the participants before the brainstorming begins, and collect the relevant opinions so as to fully mobilize the enthusiasm of the participants.
2) The number of people involved in brainstorming should also be controlled, preferably less than 10 in principle, and if there are experts or people involved in solving similar problems, the proposal for a solution to the problem has a positive effect.
3) The Division of the Conference, there should be a moderator, similar to the role of Scrum master, the overall control of the pace of the whole meeting, the atmosphere, the topic is not allowed in the brainstorming. In addition, there should be a record person to record valuable information throughout the meeting.
4) The emphasis of the discipline of the meeting does not allow the appearance of bystanders, all participants should concentrate their energies and actively devote themselves to the discussion of the problem and not allow the small groups to be discussed.
5) in a brainstorming session, members are free to talk without being "off topic", to be equal in status, and not to allow criticism, even if criticism is unavoidable and should be done after the meeting, and brainstorming will pursue the number of ideas.

6) Meeting time control, in principle, the meeting time will not exceed 45 minutes.

Fishbone diagram, usually there are two types, causal analysis type and countermeasure analysis type. One of the most common problems with causal analysis is "why ...". The countermeasure analysis is for the "How to improve/improve ..." type of problem. Analysis of the Fishbone diagram, fish head on the right side, the countermeasure analysis of Fishbone diagram, fish head on the right.

    How to draw a Fishbone diagram.
    1) First, we identify the problem that we need to solve, the problem that will be solved is the fish head, and then the fish head next to the skeleton of the Fishbone diagram, we will be directed against the backbone of the divergence.
    2) write several reasons or countermeasures on the main bone, and use the rectangle frame, after the drawing, should be as far as possible to ensure that the main bone and large bone formation of 60 degrees angle. On-Site problem: "Human machine material Law ring", management issues around "personnel".
    3) in the middle of a large bone and backbone bone, the parallel picture of the middle bone and the middle bone is used to describe the fact that the middle bone above can radiate small bone, small bone used to support the conclusion of the bone, used to describe why the middle bone in this case.
    4) when the depth to a certain level, depending on the specific situation of the question whether or not to continue, generally within the five-tier can be.
