- BEFORE You Do A 5 WHYs Root Cause Analysis Watch This Video.
In this video I'm going to explain how the 5 WHYs Root Cause Analysis Technique works and what most people do wrong. On top, I'm going to show how you can use the 5 WHYs Root Cause Analysis Technique correctly.
This Video is also appropriate for root cause analysis beginners or problem solvers using the fishbone diagram. I will show you root cause analysis examples and the weaknesses of the 5 whys.

5-Whys can't be used in isolation.
It is a great follow-up exercise to take if you've already done a Fishbone diagram and you've used that to narrow down on a clear and best contributing cause or factor of the problem.
However, if you haven't done a Fishbone, then yes, the Logic Tree combines both principles into one.
Great idea
Great video. The 5 why approach has felt intrinsically wrong compared to a multi path approach.
great insight!
Being forced to come up with a 5 why solution because Management wants it, i know the root cause but now I need to make management happy by going through this process. this solution just complicates the answer and really doesn't help. The 5 why process may work for some people but being applied globally to all problems is a huge waste of time and money for companies.
Thank you. I only knew the basic linear method, but I was a participant in a root cause analysis where the lead did it the best I have seen. I think he did with a tree. BTW it was a couple of years ago and looking back the root cause was not corrected 😔
thank you for your feedback :)
The linear method of the 5 why's should be done with data so that we focus on the right answers to the why
If I do not have any/minimal answers, this path is a good idea. A characteristic of humanity typically is that we do not like incomplete information and tend to fill that gap with "possible" reasons. This may or may not be a waste of resources depending on how one understands the challenge without resorting to a singular approach. This is a suitable method when developing multiple perspectives to avoid jumping to a particular conclusion. However, when a direct inquiry is possible, the answers collected provide a quicker path to creating a solution. The "multipath" approach may develop additional possibilities if the likelihood of a repeat incident of a similar issue arises, but it could be the result of different circumstances. The stewardship of dedicating resources to discover "what ifs" may or may not be conducive depending on other contributing factors in the environment. That to say I agree with this approach if I do not have answers and need (or crave) some to restrain irrational thoughts.
Makes sense! Thanks for sharing
5 whys in a linear way works better when you find answer that you have control over.
But what if the 5 why singular path did come up with a root cause that eliminates eliminates the issue from recurrence?….it’s possible
What if the 5 why’s singular path found a root cause that once corrected prevented 80% of reoccurrence, is that acceptable?
Let’s say the five wise determined that the reason you were late was because you go to bed late. I then correct that and go to bed and get the correct amount of time for sleep, i found that you I wake up earlier and have more time to deal with unexpected issues, i think more clearly and are less likely to make incorrect decisions like driving too slow or taking the wrong road so by keeping it simple the other issues turned out to be not likely to become issues.
I studied the root cause of an airline crash that happened in the 1970s. At the time it was the largest crash in the world. The investigators determine that the most single likely root cause was the fact they did not follow approved maintenance procedures. Oh there were many contributing factors that could be thought of as additional root causes. There was wrong tools used, dayshift and night shift did not finish their tasking, the airline company did not buy options that would have alerted the pilots to the problem earlier. Each one of those could’ve taken to another path of a root cause analysis and each one of those impacted the end desired result but in the end the investigators determined the approved maintenance procedure to install new engines was not followed and latent damages were caused in the mounting hardware of the engines. Now with an action that is complicated as that one I would say they probably use multiple tools, however it was possible even one that complex of a situation with high risk situations could’ve been done with 5 wise in a singular linear fashion
It's indeed possible, that the singular path identifies the root cause which eliminates the issue from recurring. However, I wanted to focus on not only relying on the first singular path people have in mind, but also thinking more broad about alternative paths and alternatives to the alternative paths.
My boss uses the 5 why's. Your fault, your fault, your fault, your fault, WHYYYY
How can I help you :)
@@theagilebusinessanalyst When a boss says he implements the 5 why system how do you convince him that your fault isn't part of it? Everytime we try to solve the problem he starts the your fault game.
sounds like the KT method.
What do you mean by saying KT?
Akahnda
Doesn't work for whom? It worked for me so I would like to know what you are on about. Please don't speak in generalities
Great that you have been able to solve your problem! When I referred to the statement, that the 5 whys technique does not work, I meant that very often people end in the wrong place or not the only right place when looking for the root cause. As pointed out in the video, when you ask "why", potentially there is not only 1 answer. But practitioners of the 5 whys very often think that there is only 1 right answer for the question "why". This is why they end up in a specific path, altough an alternatve path could have been the right one.
WHY did I watch this?
So, fishbone diagram then?
Actually Yes. I've already heard about the fishbone diagram before, but never really looked into it. Now I see the fishbone is actually doing the same thing as the logic tree.
@@theagilebusinessanalyst yep, pretty much. Cause and effect
This made me dangerous 😂
