This means all stakeholders directly or indirectly involved in the process. O Management surroundings (organizational, social, political) O Physical surroundings (facilities, buildings, plant, workspace, office)

O Natural environment, for instance, weather, Acts of God, temperature, humidity etc. This category includes external as well as workplace factors contributing to the effect under consideration, such as: This category refers to the group of potential causes contributed by input and output metrics for quality, quantity, process performance metrics, calibration, inspection etc. This category refers to the potential causes contributed raw materials, components, information, or data. This category refers to the potential causes contributed by the process, procedure, approach, policy, practice etc.

The technological causes are mainly related to hardware and/or software This category refers to the potential causes contributed by equipment, technology etc. It can be used as a checklist to identify potentials causes’ themes: A standard categorization technique, especially in case of manufacturing industries, is called 5Ms and 1P.

Let’s have a look at the categorization technique for the purpose of creating a Fishbone Diagram. It is a good tool to use when multiple people (and/or functions) are required to be engaged in the problem-solving effort and many perspectives are supposed to be captured. It starts with identifying all the ideas for potential causes and then groups or categorizes the potential causes into themes. The cause themes and sub-themes are placed to the left of the problem.Ī Fishbone diagram is a focusing tool. This represents the “effect” that all the subsequent causes supposedly impact. The problem is placed in a box or diamond-shape to represent the head of a fish. The relationships between causes and an effect or a problem can be depicted in the form of a Fishbone diagram. It guides concrete action and tracks the potential causes during an investigation effort to determine whether the item significantly contributes to the problem or not. It helps stimulate thinking when developing the list of the potential sources of a problem. The Fishbone Diagram helps organize ideas and understand the relationship between potential causes and an effect or a problem by formatting, arranging and organizing potential causes into themes and sub-themes in preparation for a cause identification effort.

The quality characteristics described the outcome or effect, such as length, hardness, the percentage of defects, and so on. The original objective of the diagram was to sort out and depict the relationship among the several factors impacting quality control, wherein the variables that cause dispersion, such as chemical composition, the size of parts, or process workers, were called “factors”. Kaoru Ishikawa, developed the first Fishbone diagram in 1943. Talking briefly about the history, a professor at the University of Tokyo, Dr.

Leading online six sigma courses and Lean Six Sigma training all talk about the Fishbone Diagram as it is such an important problem-solving tool for Six Sigma approach.Īttend our 100% Online & Self-Paced Free Six Sigma Training.Īccording to Six Sigma principles, root causes to problems are identified through a data-driven approach and the Fishbone Diagram is one step towards identifying root causes to problems. It is also sometimes referred to as an Ishikawa Diagram after its creator. It goes by several names, the most popular being a Fishbone Diagram because a completed diagram resembles the skeleton of a fish. The Cause-and-Effect Diagram is one of the Six Sigma 7 QC Tools.
