To create a Fishbone diagram, you need a clear statement of the problem or the effect that you want to solve or improve. For example, if you are implementing a new software system, your problem statement could be "Low user adoption of the new system". Then, you need to brainstorm the main categories of causes that could affect the problem. These categories could be based on the 6 Ms (Manpower, Method, Machine, Material, Measurement, and Mother Nature), the 4 Ps (People, Process, Product, and Place), or any other framework that suits your context. For example, you could use the 4 Ps to group the causes of low user adoption. Next, you need to brainstorm the sub-causes or factors that fall under each category. For example, under People, you could list factors such as lack of training, resistance to change, or low motivation. You can use the 5 Whys technique to dig deeper into each sub-cause and find the root cause. For example, you could ask "Why is there resistance to change?" and then "Why is there fear of losing skills?" and so on. Finally, you need to draw the Fishbone diagram by placing the problem statement at the head, the main categories at the spine, and the sub-causes at the bones. You can use a paper, a whiteboard, or a software tool to create the diagram.
