The mind-expanding tool! The Fishbone diagram helps us think beyond the person when looking for the reasons for problems.
Ask "why?" instead of "who?"
One of many ways to get us to think about the system of production, not just special causes or easy targets.
Actually, ask "why?" several times to get to the true causes.

Nice demonstration of fishbone. I've used this type of diagram/logic for several projects in the past but never put a name to it.

@rlcardcollection Год назад

I would like to go deeper into the six categories to understand the fishbone diamgram more.

@ChristopherStefan Год назад

Nice overview of the fishbone diagram. This tool is regularly used to troubleshoot processes and non-conformances in the manufacturing industry. It's helpful in finding the root cause of a potential issue.

@scotttyler1986 6 лет назад

While I have used fishbone diagrams, I never looked at them as a tool for exploring the teams mental map. I found this a very powerful interpretation.

@joshklinzing4608 6 лет назад

What I like about things like the fishbone diagram and the "tree" diagram in problem solving is that they are graphical representations of aspects of our problems. The analogies and layouts are easy to understand, and therefore help structure and direct our thinking about output and/or defect causes, giving us a chance to solve them.

@jenniferb5322 5 лет назад

i appreciated this explanation of the Fishbone diagram. During the in class activity we kept forgetting to ask, "Why". However, I do think this has practical applications within my current job role to help identify our issues and their root cause. Thank you!

@cesarlopez4907 6 лет назад

Very informative it enhances my thinking of to look at a problem, however i can see that we need to almost free our minds to just brainstorm first then formalized it in the ishikawa diagram.

@JamesBehn-pl4li 3 месяца назад

Very informative video on the Fishbone Diagram. The Fishbone Diagram is a useful tool to break down complex problems or processes. Using the Fishbone Diagram, we can brainstorm and identify what changes to test, to improve a problem or process.

@Davidconga 2 года назад

Excelent presentation!! Was pretty useful! Could you please create one explaining the Fault Tree Analysis? would be pretty useful!! Greetings from Costa Rica!!!

@GregBenz-de7nt 3 месяца назад

Very interesting concept to look at different categories of causes. I'm familiar with the "5 Whys" but didn't know that this was the origin.

@traceymathews9203 5 лет назад

Two points stand out to me when using this method for exploration. First, that these cause and effects are embedded into the way we work, which can mean so entangled they are unconsciously done . Also when using using the fishbone we must keep in mind and question both sides of things, the physical and non-physical or social.

@colleendriscoll6934 6 месяцев назад

I like the reminder to always ask why, or remember your why(s). Also, I feel like nearly anyone could make a couple of these for their business or place of employment, as there is always room for improvement. There's always a challenge. A suggestion. I'm big on analyzing and getting into the weeds to figure out the bottom line, so I can see myself using this quite a lot in my workplace.

@Student-uo1fn 6 месяцев назад

I've used this method for safety, quality and general process improvements ... always a good starting point

@BeatriceDosu 3 месяца назад

Another very informative video. The fishbone diagram visually helps to uncover the problems and their root causes. It can help in brainstorming to find the causes of problems; the ones that are not usually visible or likely obvious.

@christopherscott3264 6 лет назад

It kind of reminds me the scientific method of always asking 'why'?

@QuantativeCOD 6 месяцев назад

In the previous video, I was proactively thinking on what would be a method to bring this to people that would not necessarily understand what Six Sigma is and does. The Fish Bone diagram, along with the refined affinity diagram process is the solution. It forces you to elaborate on keen details based in sections, thus making it more palatable to whom ever presented. Yee-haw!

@Student-ws8wg 10 месяцев назад

A superior thinking exercise to empower brainstorming. The Fishbone diagram ensures teamwork to document and identify multiple causes of a process breakdown.

@sherisezynel5048 6 лет назад

Thank you for explaining the value of the fish bone diagram. It is such a useful tool to not only uncover problems but an aid in which to begin problem solving.

@adammademann4414 5 лет назад

I really enjoyed this "in class", hands on practice that we did in class. I'd never used let alone heard of the fishbone diagram, but I found it to be very helpful in breaking down the [previously] unknown causes into the 6 classification of causes that Dr. Ishikawa came up with. I also liked our instructors comparison, albeit with notable differences, to how young children practice the "5 whys" method. Clearly as adults we aim to be more pointed and prudent with our line of questioning with the goal of "peeling" back the top layers of explanations and seeking the true causes.

@jasonglatz232 5 лет назад

Fishbone diagrams are a great starting point to identify the next steps of a charter. Outline People, Method, Material, Machine Equipment, Measurement, Environment. This setups a solution for quick wins and gets the group to identify the problems of the process.

@donggunko9809 6 месяцев назад

Fishbone diagram is like putting brainstorm + 5 whys together. It sounds like an great tool, but I would like to see how it is being used in real life example.

@Samrwil-g6q 10 месяцев назад

Before this video, I didn't think about how the fishbone diagram seeks to explain a system of causes and highlight the invisible when we can simply focus on the visible.

@Music1234Man 2 года назад

This fishbone diagram seems like another very interesting tool to use. It seems that this would be a diagram that you would make before the SIPOC diagram.

@donnalevy8455 5 лет назад

Great explanation on the fishbone diagram! It is interesting going through the process not realizing that many of the causes and effects are hidden within how we work each and every day. By diagramming the causes and effects you can visually begin to see where the root causes of issues are so you can begin working to resolve them.

@oscarchiquito2609 3 года назад

From what I am understanding, this is pretty much a way to visualize cause. Every process that needs troubleshooting may use this to understand what needs fixing.

@alexissmoot6291 Год назад

I agree that causes are not visible or obvious. This problem has been the reoccurring issue across multiple departments and companies of trying to point blame versus understanding what it wrong with the system. Using the "five whys" has been an important tool that my company has begun to use multiple times.

@jameshoward6634 2 года назад

I've used these before but not with the Ishikawa template. Being more structured than the 5-why investigation this will be more useful for a process with multiple failures throughout the entire process.

@xxqqff 3 года назад

How do you go about weighting the actual effect of any of the individual fishbone causes? Just because something might be a cause, doesn't necessarily mean it is one. Is there a process for eliminating non-issues that isn't just running experiments?

@EricBennionDiaryDad Год назад

This seems like a great way to identify “low hanging fruit” opportunities for improvement while you work on solutions to the main problem.

@jdpatt904 5 лет назад

Fish bone diagrams will help identify problems you didnt think existed

@samanthadulceak7200 Год назад

The system of identifying multiple causes eliminates the finger pointing while adding employee value with the open discussion and brainstorming sessions.

@nathanfey6835 3 года назад

The corrective action process at my organization has the goal of finding the root cause. However, if someone outside the organization were to read through a sample of our corrective actions, they may find them insufficient. There tends to be a narrow focus on one or two categories towards solving a problem, without consideration to other areas. We are also lacking in a uniform and consistent approach to root cause analysis. If we were to introduce and train on the fishbone diagram, I believe we'd improve our root cause analysis by encouraging structured pathways of investigation and making sure we've considered all categories prior to closing out a corrective action.

@vaniavargasjimenez2358 3 года назад

I understand that is a brainstorming session with stakeholders, but after doing the fishbone by myself I realized that you have to have different points of view in order to do this activity successful.

@sblackmore27 6 лет назад

By using the 5 why's you can keep peeling away the layers of the problem and get to the root cause of the issue. The diagram helps to bring out the system of causes during a good brainstorming session.

@RogelioG52 4 года назад

Keep asking why until you find the problem.

@williamhansen4837 4 года назад

i have used the 5 way method both internally and externally from a customer request, i like the fishbone method because its not only a visual tool that every one can see but it encourages a natural collaboration that can be a lot more effective than a email with a PDF back and forth between peers who are not fully engaged with it anyways.

@lettyorozco3521 5 лет назад

If problems can’t be identified in 6 categories should additional diagrams be constructed until a root cause is identified?

@mariaflores-tl1gk 3 года назад

Fish bone is a creative way to collect ideas, find the root causes of a problem and plan for changes and implementation.

@patriciazuno1694 Год назад

Before we jump to the conclusion that something went wrong because of one person, we need to look at the picture as a whole and break it down. Looking at how each aspect impacts the outcome is critical to know where things may go wrong and implementing actions to control these situations.

@ryananderson8130 2 года назад

I think it is important to remember we are still not trying to solve the process breakdown we are trying to identify it. Another good tool to locate issue within the 6 categories.

@rebekkaherrington4509 3 года назад

I can see how this tool can help guide deeper exploration of the problem and help avoid clinging onto the first assumed cause as the sole area needing fixed.

@nicholaspesek5902 3 года назад

This video pairs well with the in class material. This tool will help to structure the 5 why process and get to the root of the problem.

@ryannew907 3 года назад

The fish bone diagram is an excellent tool to use when trying to find the why not The Who. This helps us get down to the root causes and then make a fix.

@stephenfaleti7529 6 лет назад

What if the Root Cause cannot be identified from the 6 categories listed. Should more variables be added and explored, for example, regulatory changes or constraints and other environmental factors.

@fkiQuality 6 лет назад

STEPHEN FALETI yes, do not feel constrained by the categories, they are a valuable starting point.

@leonardcarlson8839 6 лет назад

I have seen the process in action and I have seen it used wrong. It is best when you make sure what you are documenting are what is happening not what you think is happening.

@joshturnbull1850 3 года назад

The Fishbone diagram is a great tool that requires you to look at every part of the process to make sure you find the root cause.

@brief1206 4 месяца назад

Hello! Thank you for this lesson, you are a great teacher

@margaritorios 3 года назад

following the fishbone diagram is going to give us a better idea how to solve a problem

@karlajohnson8017 4 года назад

Ask 5 whys-free brainstorming to get to Hidden 6 categories (Data/material, people, machines/tools, method/procedures, how measured-physical & social/behavioral, physical & social environment)of Causes of the affect-I like this because it makes causes and affect visible

@fkiQuality 4 года назад

Karla, in addition to the 5-why's, you can use the fishbone along with the control chart in this way. As soon as the chart indicates a signal of special/uncontrolled variation, study the event by putting it in the head of the fishbone and ask "why" several times to get to the root causes. Now, sometimes the reason for the variation may be staring at you in which case you just need to try a change, see what happens and standardize the change (this is called the PDSA cycle).

@bradhentz7102 6 лет назад

This video mentions the fishbone diagram as well as the "5 Whys" multiple times. Towards the end of the video it sounded like the fishbone diagram is a derivative of the "5 Whys" methodology resulting in 6 broad categories. Am I understanding this correctly? Regardless, it seems that the "5 Whys" and Fishbone diagram are complementary methodologies wherein once the broad Fishbone categories are explored, the 5 Whys could be applied (again?) to really get to the more specific root causes?

@fkiQuality 6 лет назад

Brad Hentz the 6 categories are Ishikawa's guideline to look for causes. With or without these categories you may need to ask to uncover root causes. So, they are complementary techniques. Another one is brainstorming.

@mikhailsirota9556 4 года назад

Good system for finding the root cause of a result

@rafaelhernandez1981 3 года назад

Fishbone diagrams seem like a very useful tool for troubleshooting any kind of complicated problem. Doing it all in your head on such issues can have you spinning your wheels very quickly.

@fkiQuality 3 года назад

Good point, and keep in mind that the fishbone diagram should always be done with the participation of the team who knows how the work is done.

@aaroncrenshaw6540 4 года назад

The Fishbone is great, due to it is design to be hard on the process and not the people.

@cindygaborik4941 6 лет назад

Six Sigma Class - Fishbone diagram and asking 5 whys for root causes are helpful tools to getting to the true reasons for problems.

@fkiQuality 6 лет назад

The fishbone is supported by tools such as the 5-whys, brainstorming and affinity grouping. It requires strong facilitation to keep the discussions going and avoid too much consensus which risks situations where everybody agrees on everything like "it's all because of lack of training."

@Bittersweetdstny 10 месяцев назад

This reminds me of the Pros/Cons list we were taught as children. It's a logical approach to solving problems and finding the root cause to brainstorm solutions. Just keeping analyzing and asking why.

@ss-fs9gz Год назад

Significant in detail explanation!

@КсенияФедосеева-ж5ю 3 года назад

Very helpful thank you!

@Ace_theMaster 2 года назад

When conducting the development of Fishbone Diagrams or Affinity Diagrams, I do like the concept of giving people (the attendees of the meeting) some sticky notes (maybe like 3 per person), so that they write the ideas on the sticky notes themselves and then also let them put the sticky notes on to the diagram. I feel this small task inspires a sense of responsibility and ownership of the "process" for each person who participated in the activity, and thus, this exercise creates a great team-building experience for everyone.

@mattmack8103 3 месяца назад

Asking "why" multiple times is a terrific way to get to the get to the cause and effect. I've used this method with customers, and never knew it originated from the fishbone diagram.

@alanharker2433 4 года назад

I am a firm believer in asking the WHYs bc it will answer the root cause of a lot of current issues. I've been asking why the last couple days in several projects and slowly getting the same answer from each area. Placing this in a diagram would be a great visual tool to share the common issue spread through multiple departments. Great recap/ quick explanation.

@michaelparks8673 5 лет назад

Very good explanation of a Fishbone diagram. I have used the fishbone before in problem solving but with only 4 attributes.

@mitchzavesky4734 2 года назад

We just refer to this as "brainstorming sessions," but we do a similar version of a fishbone diagram when designing new product. We focus on different aspects of our product, and using sticky notes, all members can voice what they would like to see improved. In a similar vein, the fishbone diagram works to find the root cause of a problem by asking "why" and really diving deep into the problem.

@kimdaniels1736 6 лет назад

I've used the fishbone method(5 why's as well) to help drill down into the actual root cause of a particular problem(s). It's important to get the problem statement correct otherwise there can be scope creep or the issue can be defined too generally making it harder to drill down into specifics. I've found that using an IS and IS NOT table, helps stimluate the thinking of the inputters. Lastly, it's easy to get into "problem solving mode" instead of brainstorming possible causes; the facilitator needs to be strong in re-directing the team if they begin to go down a rabbit hole.

@johnstanley491 4 года назад

I've used several different root cause analysis tools. I think the Fishbone diagram is great because of it's simplicity and accessible visual way of organizing information.

@Ganjagoddessgrower 6 месяцев назад

The fishbone diagram is really helpful to provide structure to brainstorming sessions-which can be too random and get off track. I like that it is fast and easy to explain to others.

@sherryclayton1778 6 лет назад

The team's ability to exercise trust during questioning process is key. Sometimes people will either panic, withdraw or push-back at probing questions. It's usually recommended that the "whys" go at least 5 levels deep. If a culture of trust does not exist within the team, that process is likely not going to be productive due to negative reactions. The question becomes how to build that trust if the organization is currently in flux?

@kieshabracy7670 6 лет назад

Unfortunately, I haven't had the chance to utilize this particular diagram on any of my past projects, but based on the structure of how it helps to identify the cause of an issue is very helpful. That said, I look forward to utilizing this particular diagram on my future projects.

@musicotriste69 3 года назад

Homero Cardoso: This is a very useful tool to brainstorm problems and their causes. Visualizing in the diagram all of the problems and secondary problems give us a clear picture of what path to take to solve the issues.

@kirin357 2 года назад

Awesome. Thank you

@antrioneday1272 6 лет назад

The fishbone diagram is the best tool to use for investigation. It's a productive tool for laying out all contributing factors to the problem at hand. It has also allowed me to identify latent weaknesses within my process. I find useful when I include the Why-Why analysis. But alone it is very helpful.

@christianhagner6509 2 года назад

This is great, I was introduced to the fishbone diagram in college, but was never educated on all the facets of proper use, so I never used it. I'm excited to see how I can apply this to my current job.

@kristukker5279 6 лет назад

Take it from our kids. Asking "Why?" over and over is a very natural way to learn about our environment, our systems, and our processes.

@jamesmcelwee5666 6 лет назад

I have used this in problem solving as a PMP before. It is very effective in getting to root causes when accompanied by the 5 Why’s technique.

@victorgomez1437 3 года назад

Fishbone diagram in collaboration with the 5 why's makes for a great system for brainstorming many problems.

@stacieevans139 6 лет назад

fishbones are a good visual representation of a 5 why method of searching for the root cause. It is a very commong tool when performing OOS/OOT investigations.

@MarytheBad 2 года назад

Thank you very much!

@christopherrogers7303 2 года назад

Seems like an extremely useful tool, not sure I am ready for this one just yet. I can see how sitting down with a few employees and using this diagram to capture their reasons for a failed process can be effective as far a fostering inclusivity and also building trust within the department(s).

@cocor3672 5 лет назад

We have to always ask questions why. Ishikawa's categories of things can be used as guidelines mental map to help us brainstorm all of possible causes.

@nsmith9976 6 лет назад

The fishbone diagramming forces brain storming through examining 6 main branches or categories. The smaller branches narrows the path to the realization or discovery of the root cause and ultimately problem resolution.

@denisek743 5 лет назад

The six categories recommended by Ishikawa are great for getting the root cause. Then asking the 5 whys. And finally using the fishbone diagram to bring it all together.

@maureenurchel8835 6 лет назад

Fishbone diagrams list of series of causes. They are grouped into 6 categories (materials, person, machine, methods, measurements and environment. I like the idea that once you are good at this you can brainstorm your own diagram.

@karimerrills207 5 лет назад

There are many causes that can effect why something has occurred. The best way to narrow down what is causing the variation you have to ask why multiple times.

@fkiQuality 5 лет назад

Kari Merrills, a prerequisite for asking "why" is to be willing to go deeper and to think broadly. In this sense, the fishbone and 5-whys techniques are mind-opening.

@ernestbroom9995 6 лет назад

I like how the Fishbone diagram gives a focused way to brainstorm. It gives 6 categories of focus on when narrowing down ways to find our solution. Awesome!!

@GlennFrazee 2 года назад

I'll admit that looking at this in the course materials, I was having trouble knowing how to get started. But the in-class exercise where we went through the Fishbone Diagram really helped the idea sink in.

@mmaphefoseseni6625 3 года назад

Very informative

@scottslomka2667 6 лет назад

Using the Fishbone diagram can be an uncomfortable experience the first time around. Everyone needs to be made aware that there are no bad/wrong ideas! To start out, the group leader may ask everyone to write out 1-3 possible items on sticky notes and then put them all in a hat. Leader can then pull them out and read them 1 by 1 and put them onto the diagram.

@jeffreysundwall7812 6 лет назад

This is an organized way to do brainstorming and free association. As we know, Ishikawa promoted the use of Quality Circles and I am sure that the diagram was used in that exercise as well.

@joycestadter945 6 лет назад

Fishbone diagram is a good way of further exploring problems within the system.

@slee3249 5 лет назад

this helps to break down the problems into categories that are visual. And it helps to identify some of problem for quick wins.

@danagreene6800 4 года назад

This helped understand the fishbone diagram, having more tools. Thanks

@MustaqueAliPMP 6 лет назад

The 6 causes recommended on the Fishbone diagram is manageable, however if there are large number of causes, it would be interesting to see if there is a maximum limit to Ishikawa method.

@nicholashumphrey8654 3 года назад

I can see how this can be used with the entire team to both add ownership to the operation and get down to the nitty-gritty of what is really the cause of the problems. It is easy to think you know what the causes are, especially if you are in the work. But by having an open forum and brainstorming together you will realize the hidden causes.

@mitchellhoem2003 2 года назад

This is a great tool to use with your employees. Those performing the work know the ins and outs of each of the categories of a Fishbone Diagram better than anyone. Sitting them down and working through one of these diagrams will help to educate management and find ways to improve processes.

@miawang7632 4 года назад

Love this cause-and-effect analysis -- it allows us to see the overall picture of a problem, and to reach deeper for the root causes of a problem. We can apply this method to work and life in general.

@tedkozelka203 6 лет назад

This is an excellent tool for unlocking tribal knowledge to help find underlying causes.

@jeffmaes5892 4 года назад

This is a great visual tool to find a problem in an existing process or identifying potential problems when building a new process.

@jorgecifuentes7283 5 лет назад

We just started to learn about the fishbone tool and this video has added value by further clarifying its purpose and method for getting to the end result. I can see how following this method would help because it adds the structure needed to maintain alignment with the desired results of getting to the root cause. Definitely a useful tool. From personal experience, I have been exposed to the free brainstorming process but see the value for using the fishbone method first.

@kennethmckillip3983 6 лет назад

I have used these before. The one thing to keep in mind is that they work better when done as a team; not solo. The various ideas that come from "picking others brains" or as it was stated, using their mental map, is invaluable.

@sheiladwyer6482 6 лет назад

I like your suggestion to use this tool multiple times initially as you develop a comfort level and learn to use it effectively. Once you develop that comfort level use it for free brainstorming and/or affinity diagram. I don't have much experience using it but I can see its utility in getting to the root cause.

@ronaldtucci6091 6 лет назад

Fishbone diagram is very helpful when leading a team to explore for root cause analysis of a defect. It helps keep the team on track and opens up all possible issues.
