Put the answers of the two questions together. How easy would it be to fix or control?.How likely is this cause to be the major source of the issue or variation?.An easy Cause screening method involves looking at each one and asking two questions The Next step in the fishbone problem solving tools is to prioritise or screen the causes to determine which are having the largest effect. We have added some examples below.īelow is an example fishbone diagram for a package delivery company, struggling with late deliveries. Step 3- Add the causes relevant to each input on the horizontal lines. (You can put anything in the input boxes but the six listed below are a good guideline.) Connect the inputs with lines to the arrow. Step 2– Put the inputs to the process at a distance above and below the arrow. Draw an arrow to the left pointing at the effect. Step 1- Place the problem or the “Effect” on the right side of the page. However, always keep your specific effect in mind, if absenteeism doesn’t factor in your problem, don’t list it. Under people absenteeism could be causing your undesired effect. To make a fishbone diagram follow the steps listed below.Īn example of these aspects could be under machine the start-up time may be a factor. A white board is also very useful in a large brainstorming session, you can take a picture after and transfer the diagram to PowerPoint or just save the picture. Once you’ve finished or have gotten the hang of it you can transfer to your computer. This allows you to quickly make changes and gives flexibility when you or your brainstorming team has a new thought about your diagram. I suggest that for your first few attempts use a pencil, a ruler and a rubber to make your diagram. Looking at elements of the problem and not the whole process will likely make finding your solution less daunting and problem solving more manageable. This structure also allows you to tackle smaller chunks which have a large impact on the problem. One or two of these “causes” will have a greater effect than the others and will guide you to the root of the problem. Grouping the “causes” means you can think about the different elements of the problem as separate from the overall process. A fishbone diagram aims to break down and organise the Causes of an issue to reveal what elements have the greatest impact. WHY IS A FISHBONE DIAGRAM A GREAT PROBLEM-SOLVING TOOL?Ī recurring theme in a lean or six-sigma transformation is removing the clutter to allow you to see waste or opportunities for improvement. Using this structure removes the clutter and may allow you to see things you missed before. In this capacity, the advantage of the fishbone diagram is gaining a greater understanding of how elements of the process result in the outcome. If you are completing a DMAIC project you would use a fishbone diagram in the Analyse phase.Ī Fishbone diagram can also be used to analyse a new design, understand a current process and highlight opportunities to optimise the existing process. It is important that those closest to the issue complete the diagram or be involved in the brainstorming session to make it. Before you can create a fish-bone diagram you must have an in-depth understanding of the process or the problem.

A fishbone diagram can also be referred to as a cause-and-effect diagram, Herringbone diagram, an Ishikawa diagram (after the man who invented it). They are named for their shape which, when completed looks like a fish’s bones. It is used to figure out cause-and-effect and to breakdown the contributing factors of an issue.
