5 Why Analysis

Lean Training Video

I’ve gotten another Lean video rolled out. This one is on the 5 Whys. If you are not familiar with it, the tool is useful for diving down to the root cause of a problem.

Please take a look at it and let me know what you think. Rating it well on YouTube, where I have it posted, will certainly help me. I’d also appreciate any comments on this page if you have ideas to improve future Lean videos.

If you want more detailed information on the 5 Whys, download our 6-page PDF file from our downloadable continuous improvement reference guide.

If you like this video, please help support this site by giving my 5 Why Root Cause Analysis Lean Video on YouTube a good rating.

    I have heard and read about the “5 whys” before, and I have even used the process a few times to get some answers for problems. You have found a way to make it simple and effective. I am so glad you pointed out that it should be used for simple and not too complex problems. I am finding that it helps to hear simular things form different people about these lean subjects.

    Thank you for creating a very simple to understand introduction to the 5 Why process.
    I was also pleased that you added the drawbacks of it also, as our team came across those very same ideas, without prior understanding.

    I was interested in your comment that the 5 why’s are useful mainly for those less complext problems.

    I will share your video with my team at work.

    Also, wish to thank you for a great website!
    I’m off to check out your book!

      Thanks for the comment. I always appreciate hearing that my work is helpful to people.

      And thanks for sharing the information. My site thrives when people spread the word.

      By the way–if you haven’t seen the forms page, I have a 5 Whys Worksheet that requires confirmation steps along the way. It is a method of combining the 5 Whys with more quantitative tools to be more accurate in finding the real root cause. It mitigates some of the drawbacks of using the 5 Whys with more complex problems.

      Thanks again.
