How to Perform Five Whys Analysis On the surface, the Five Whys process is very simple: simply ask “Why?” five times to get down to the root cause of a problem. However, there are some best practices to follow to make sure it’s effective. These steps can help you perform Five Why...
In this option, the tail of the fish is the main problem, each of the whys goes along the sides, and the final effects (or root cause) are up front. This allows those performing the analysis to easily write down known problems along with the whys that helped to find them. ...
How to conduct a root cause analysis using “the five whys” format What Is A Root Cause Analysis? A root cause analysis assumes that any critical failure is not the result of a single event, but a chain of events starting with a root cause. You can think of each of these contributing...
According to Minoura, the Five Whys do not ensure that the root cause analysis will be successful. One downside of the Five Whys exercise is that brainstormers tend to mistake symptoms of the root cause for the actual root cause. When this happens, participants tend to stop investigating, ...

Date: 12/20/04 Page 1 of 4 The Five-Why Process The Five Whys have been used as a root cause analysis tool for many years. The approach uses a systemic questionnaire technique to search for the root causes of a problem. The depth of layers of questions and answers is not set in...
In fact, at IMVU, we did exactly that. We started with a simple wiki page with a few bullet points of things that new engineers had tripped over recently. As we kept doing root cause analysis, the list grew. In response to Five Whys that noticed that not all new engineers were reading...
I did my first 5-whys analysis this week. The LW team has just run a big in-person event, and I got all the team together to go through about 4 of these. One main issue I ran into is that at every step of the 5-whys, there were a bunch of different things that could've ca...
Here's how to use Five Whys analysis to build an adaptive(相应的) organization:consistently make a proportional investment at each of the five levels of the hierarchy. In other words, the investment should be smaller when the symptom is minor and larger when the symptom is more painful. We...
Once that responsibility has been assigned, have that new person emailthe whole companywith the results of the analysis. This last step is difficult, but I think it's very helpful. Five whys should read like plain English. If they don't, you're probably obfuscating the real problem. The ...
