In the same way, it is a question of finding appropriate solutions to improve the problem. Material: waste of paper (faulty printer).Equipment: insufficient number of cash registers, delivery trucks often breaking down.Manpower: lack of motivation, lack of staff and lack of training.The dissatisfaction is due to supply problems, long waiting times at the checkout, a gloomy environment and a printer failure.įrom this information, the causes can be sorted as follows: In the same way as in the previous example, an analysis is carried out to identify the potential causes of this dissatisfaction. Let’s take another example: a drop in customer satisfaction in a clothing shop. Ishikawa diagram: example of a drop in customer satisfaction in a clothing shop In our case, for example, they can apply the 5S method to improve the working conditions and the organisation of the environment, and thus restore motivation to the operators. They can then focus on the causes they consider to be predominant. Environment: overly intensive working conditions and poorly organised environment.Īfter identifying and sorting out these causes, the teams can find appropriate solutions to improve the problem.Material: delay in raw material supplier, shortages.Equipment: failure of electrical equipment, damage to certain machines.Manpower: lack of motivation, lack of personnel and lack of training.The production delay can be due to multiple factors, which are classified into the major families ( 5M). An analysis is then carried out by the managers and operators of the factory to identify, during a brainstorming session, the potential causes of this delay. In our problem, the factory suffers from a production delay. Let’s take a first example of a problem in a factory: a production delay. Ishikawa diagram: example of production delay The last step is to list the action plan to reduce or eliminate the causes of the problem. Once these 5 branches have been drawn, the causes listed during the brainstorming are taken up again and divided into the different families of causes. These 5 branches are the 5Ms, which, as we have seen, represent the main families of causes of a given problem. Once the problem has been specified, the next step is to draw 5 branches that will point to the continuous line. On the far left, the name of the problem is written as specifically as possible. The Ishikawa diagram consists of a continuous line or arrow that indicates the problem.
Drawing the Ishikawa diagram, to graphically represent the causes of a problem and rank them.Think about all the causes that could explain the problem, in the form of a team brainstorm,.The process of constructing this diagram is carried out in several stages: It is therefore the visual tool of the 5M method. The Ishikawa diagram, also known as the cause-effect diagram or the 5M diagram, aims to identify and organise the causes of a problem into large families, in a visual way. Management, which refers to hierarchical responsibilities and decision-making.Money, which refers to sources of funding,.It can also be completed with the following elements: When this family of causes is added, the 5M method becomes the 6M method. The 5M method is sometimes completed by other aspects, such as the Measure, which refers to the method of measurement, calibration or the readability of the results. The Environment: environment, working conditions, relational aspects….The Method: way of doing things, procedures, instructions….Materials: consumables, elements processed in the production chain….

It is structured around the 5Ms, which designate the main families of possible causes for a malfunction. The 5M method is a project management tool for analysing the causes of a problem.
