The advantage of this diagram is that it limits the attributes to 4 factors while trying to broadly capture all key attributes, which helps focus on the underlying problems without expanding into too many attributes or departments. The 4S of the fishbone represent suppliers (or simply input sources), skills, surrounding (any surrounding factor, including real-estate or office space) and systems (including computer systems).

The 4S fishbone diagram (example above) is a standard manufacturing and industrial problem solving tool, however it can also be used for any product development process, including software development. For example, while trying to analyze website traffic, one may choose to divide them into just 2 channels – organic and non-organic sources. This diagram is used to solve problems where the causes can be grouped into two attributes.

Here are the 4 key types of fishbone diagrams commonly used today:Ī simple fishbone is made up of only 2 attributes with causes attached to the main head representing the main problem to be solved. While the underlying method for any fishbone remains consistent, there are certain types that are widely used and serve as a standard template. A fishbone diagram layout is a great alternative visual tool to show how multiple contributing factors are together causing the main problem, and how each of these root causes will need to be addressed in order to treat the main issue. Easily presentable visual aid: One of the key issues with trying to solve a problem where the root cause or causes have been identified – is explaining this complex structure to company leaders and getting their cooperation.This allows for holistic analysis and problem-solving, where symptoms are not ignored, while being cognizant that the root cause needs to be identified to solve the larger problem. A fishbone diagram starts with the goal of trying to identify the root causes, with the symptoms also getting their place in the diagram. Real problem-solving over treating symptoms: Often brainstorming sessions or company meetings may be spent trying to deal with symptoms of a problem, such as lower sales numbers or employee attrition, without trying to get to the root of the problems.Furthermore, the layout of the diagram allows one to incorporate both internal and external factors during analysis. This allows one to expand the diagram to as many attributes and root-causes as needed without being overwhelmed by the sheer number of underlying issues. Visual problem solving: A fishbone diagram’s key utility comes from the fact that it is visual versus being a list or a spreadsheet.Here are some of the factors that make fishbone diagrams an important business tool: Each ‘s’ factor is accompanied by adjoint ‘bones’ which represent the issues in these attributes of the manufacturing process.īelow is an example of a 4S fishbone diagram: 4S Fishbone Importance and Purpose of Fishbone Diagramsįishbone diagrams are often seen as a problem solving tool, but they can also function as an excellent visual aid when issues need to be explained and co-ordinated with larger teams. The 4S’s represent – systems, surrounding, skills, and suppliers. The problem areas within the attributes that are the potential causes of the problem on the head.Īn example of application of a fishbone diagram will be the typical 4S fishbone used in manufacturing.The attributes that form the key function as the bones stemming out from the spine.It is widely used in manufacturing and industrial services, product development, or just general troubleshooting of problems where the cause is unclear.Īny fishbone diagram has 3 key components: Top 5 Best Practices for a Fishbone Diagram in 2023įishbone diagram (also known as the Ishikawa diagram) is defined as a ‘casual diagram’ methodology that aims to find root causes of specific problems.
