![]() The main reasons we identified were “Why did this problem occur?” are asked separately, and sub-headings are determined. Step 4: Identifying the Subtitles of the Causes New ideas that emerge are written under the appropriate title in the fishbone diagram. Basically, “Why did such a situation arise?” search for an answer to the question. Generally, at this stage, the type of titles you will see below are preferred.Īll possible causes of the problem are considered, and a cause-effect relationship is established between them. The main reasons chosen are written as headings over the arrows drawn at 45-degree angles around the horizontal arrow. This identified problem is written at the end of the line as the head of the fish and framed around it.īrainstorming is done about the main causes of the problem, and the main topics to be used in the diagram are determined. The main problem is determined by brainstorming within the group. The method and diagram are created in 5 stages.Ī piece of paper or blackboard is taken, and a straight line is drawn from left to right. Then, by working on this characteristic, the causes are investigated. In this way, essential characteristics for the relevant situation are first determined. It is mainly used with Pareto analysis.This brainstorming is inevitable to capture reality. While investigating these reasons, the opinion of as many experts and experts as possible should be sought. Then, the main and sub-reasons are added to the chart, and the diagram is completed. Measurements: Process-generated data used to evaluate the qualityĮnvironment: Conditions such as place, time, temperature, and culture in which the process operatesįirst of all, the relevant quality element whose causes will be investigated is written on the far right of the graph. used to produce the final product of the type Materials: Raw materials, parts, pens, paper, etc. Machines: Equipment, computers, tools, etc. Methods/Methods: How the process is run and specific requirements such as policies, procedures, rules, regulations, laws Human: The people involved in the process. And these categories mostly include the following. Causes are often divided into main categories to identify these sources. A fishbone diagram can be used when there are difficulties in establishing a cause-effect relationship.Īll the causes that create the problem are caused by some source of change.When thoughts start to get monotonous during brainstorming.When identifying possible causes of a problem.To see together the different ideas that arise while working as a team. ![]()
