Mazda Motors used fishbones diagrams to design the Miata (MX5) sports car. ![]() Details down to the design of the car’s doors, so drivers could rest their arm on it while driving, were considered. In nearly any industry or business, variation is quality’s and efficiency’s kryptonite. Once an order has been placed, a predictable and standardized process should be followed through to delivery. Variation in that process usually means variation in the final product.įishbone diagrams are a great tool to either determine potential variables in a process to mitigate defects or failures, or to figure out what’s causing a defect or failure that is currently occurring.Īdvantages and Disadvantages of Fishbone DiagramsĪs we dive into when and how to use a fishbone diagram, it’s important to note the advantages and disadvantages that can present themselves when using this root cause analysis tool. The process of asking why something happened repeatedly at each stage helps drill down to one or more root causes, The brainstorming process encourages broad thinking, keeping teams from limited thinking patterns that can lead to getting stuck, Help facilitate joint brainstorming discussions, Help identify cause and effect relationships with underlying problems, Advantages go in accordance with the purpose and method of the diagram. Help prioritize relevant causes, so underlying root causes are addressed first. Some disadvantages that can present themselves relate to the greatest strengths of the fishbone diagram. The brainstorming process can produce irrelevant potential causes along with relevant ones, which can result in confusion and a time drain.Ĭomplex diagrams with multiple factors can lead to a jumbled mess that is too difficult to display in a fishbone diagram.įishbone diagrams can lend themselves to the divergent approach – the temptation to identify and fix everything that might be causing the problem. This usually leads to a low success rate because hardly any team has the resources to fix every potential cause. Helps prioritize relevant causes, allowing you to address underlying root causesīased on opinion rather than evidence it needs testing to prove results Works well with the 5 Whys to drill down to a root cause quickly Helps develop in-depth joint brainstorming discussionĬomplex issues may lead to a messy diagram Irrelevant potential causes can cause confusion Helps identify cause and effect relationships For example, if you complete a fishbone diagram and it has 40 potential causes, the team will be left feeling like the problem is too big to handle. One of the first steps in creating a fishbone diagram is determining the factors that contribute to variations within a process. Ishikawa describes these contributing factors as the 6 Ms in the manufacturing world: man, machine, method, material, measurement and Mother Nature. These 6 Ms influence variation in all processes and serve as the first six main “bones” of your fishbone. All my rifle caliber JP's get spec'ed out with the Thermal Dissapator.Let’s take a look at how the 6 Ms are defined and how they can contribute to process variation. ![]() We have locally had Hosefest matches designed with the goal of 50 rounds into paper in ~15-20 seconds. Vortex 3 gun had a 60+ round rifle run with 50+ close paper shots followed by 10ish longer shots at the end. ![]() Some matches are getting to be wicked tests of whether a rifle has a POI shift after heating. Removing heat from the barrel lets me shoot more efficient practice sessions. I couldn't go without the Thermal Dissapator in any build though. Some friends in the Florida area don't see shots past 200 yards though so they go super light. I found that the PRS stock and extra weight helped keep me stable on the long range and get first round hits easier but the matches in Texas emphasized the longer shots. I also like a relatively heavy 3 gun rifle but rather than dropping weight at the muzzle with Ti I prefer adding weight in the rear with a Magpul PRS stock. Weight is one of those things that folks find their own balance on based on preference.
