The goal is to end the brainstorming session with a list of causes to add to your fishbone diagram. Have someone lead the session, taking note of any ideas team members offer up and leaving room for discussion. That’s why it’s worth making sure your brainstorming session takes the shape of a clearly-defined meeting. When working alone, it’s easy to overlook certain areas and completely miss others. Instead of considering all the factors of a fishbone diagram by yourself, include others in the process. Brainstormingīrainstorming is a fairly common tool in modern businesses. In other words, it helps you clearly identify potential causes and add them to your fishbone diagram. In an actual manufacturing environment, this may include being present on the production line and viewing the system, taking notes as you go through the process.Ī process map is very effective at making sure you consider all the steps and influences involved in a system. Process mapping involves looking at each step of the process one by one and listing all the potential influences. It works best in areas like the manufacturing industry, where each product has a clearly defined process with multiple steps. Here are a few more tools to help you take your fishbone diagram to the next level: Process MapĪ process map is a flowchart of a specific system, showing all its inputs and outputs. In fact, part of learning how to make a fishbone diagram is knowing what other tools you can use to identify causes more effectively. Remember, a fishbone diagram helps identify a problem’s causes. Step 4 – Using tools to plan the way forward Expand your fishbone diagram as needed to encompass all possible causes. Some causes may have multiple sub-causes.Invite other team members in the process to make sure you’ve identified all the potential causes.Run a brainstorming session or lay out a process map to generate better causes for your fishbone diagram.The Fishbone diagram – determine actual causes Tips to determine the actual cause: To keep going, investigate each cause to establish its actual effect on your output. Regardless, you now have a starting point to determine root causes. Some might even have more causes than others. Note that not every area of your diagram needs to have causes. You should fill your fishbone diagram with as many different causes as you can come up with. Key functionality requires additional subscriptions.Software installation requires multiple plugins to function well.The software is unstable and crashes regularly.When it comes to the software itself, potential causes may be: Users don’t use the software continuously, only requiring it for a few days at a time.Users experience delays when contacting support.Users don’t know how to use all the functions.Users don’t understand the full benefit of the software.When considering the user, potential causes include: The system doesn’t send out reminders for renewals.The payment and registration systems are difficult to navigate. We aren’t offering enough payment options.Looking at the subscription system, some possible causes include: Look at each category and list every possible cause you can think of. Now that you’ve defined the key areas to look into, let’s go through each one to determine all the individual influences that can affect our output. The Fishbone diagram – decide on the key areas Step 3 – Determine the actual causes of the problem But to keep things simple, we recommend limiting yourself to no more than 10 - especially since we’re only learning how to make a fishbone diagram with this example. You can have as many areas as you need to. For example, If you think marketing impacted your retention figures, you could add that as a fourth area. But you can always add more categories if needed. Once you start considering potential causes, you might find that most of them fall within one of these three categories. Going back to our example of investigating a high churn rate, here are three areas worth looking into: Next, decide what areas of the problem are key to determining the actual cause. Step 2 – Decide on key categories of causes Place the causes with the biggest impact closer to the fish head and the causes with the smaller impact further away.The idea is that the “fish bones” indicate the impact of the causes. Place the problem (the fish head) on one side of the diagram, and build the rest of the diagram (the fish bones) out to its left or right.Your goals should be objective and achievable. If you’re using the fishbone diagram to design a process or increase productivity, it’s just as important to correctly define your output.
