In general, a check sheet will include headings that provide the following information: The total number of each type of problem is also recorded.īelow is an example check sheet for quality purposes. The check sheet is divided into a number of different regions, and data is then marked into the different regions using different types of marks to indicate different types of problems. People often use check sheets to collect data on the frequency, location, or even cause of problems or defects that occur during production. It’s typically created at the location where the data is created, such as at the end of a production line. Use what works best for each scenario.Ī check sheet is a sheet or form you can use to collect and then later analyze data. For other problems, you may need to come up with your own causes.īecause it seems that nothing’s ever simple and easy, you will sometimes seen this listed as the 5 Ms (machine, method, material, man, measurement) and even see it sometimes expanded to 8 Ms (including mission, mother nature, management, and maintenance). You can’t use the 6M cause-and-effect diagram for every situation, but it can be a helpful way to begin organizing thoughts for many. In analyzing production processes, the 6M fishbone design is often used. Each bone represents one possible major cause of the event. You can add smaller bones branching off each major bone to represent sub-causes related to that major cause. The “bones” of the fish branch off the central, horizontal spine and angle backward to the left. The head represents the problem or cause. You should always draw the “fish skeleton” of an Ishikawa diagram so that the “head” of the fish points to the right. In addition to using fishbone diagrams to identify the cause of an event, people also use them find the cause of a problem or for other reasons. Here’s an example fishbone diagram in the image below. It’s also known as a cause-and-effect diagram because it’s often used to show the cause of some effect. This is especially true for control plans.Quality Tool 1: The Cause-and-Effect Diagram (also known as Ishikawa Diagram and/or Fishbone Diagram)Īn Ishikawa diagram is also known as a fishbone diagram that’s because it looks like a child’s drawing of a fish skeleton.
