    Thanks for the video. Do you also provide pdf file or such book for learning or just a video?

    Is there a way to download the slides? Th Flash plugin isn't working on my browser which makes the slides not readable. Thanks

    Awesome! The best balance in theory and examples. Thanks for sharing!

    Thanks for the feedback, Arif. Yes, there was a way to expand the videos to full screen, however, the code recently changed from my provider and removed that capability. I just got it fixed so by clicking on the arrows at the bottom right of each video it should expand it to the full screen.

    Hi Matt,
    Thank you very much for sharing all these information for free.
    I have a very simple question: is there a way to watch the videos at full screen?

    Siju, thanks for your feedback about StatStuff and checking out the site! I'm glad it's been a help to you.

    ASQ is one of the most popular sources for getting Lean Six Sigma (LSS) certified, however, that doesn't mean it's the "best". In my opinion, their cert requirements (like many other training orgs) are not very stringent and I've seen many folks get certified by them who were not at all capable of applying LSS; those folks knew enough to pass the exam, but had not practical application of LSS. And no, their requirement of completing a project or two is not sufficient; they do not validate the person's LSS skills nor the actual completion of those projects. Despite this critical gap, I don't necessarily think this means they're "bad" or not worth pursuing. I tend to advise only those who have already proven their application of LSS in real-world situations to pursue a cert from ASQ since they're an affordable choice. If you haven't already seen it, I recommend you check out this article I wrote that explains this in more detail:

    Based on my above comment, there's no particular book I'd recommend to pass the ASQ exam. I'd only recommend you find whatever resources help you learn the most and then apply what learned - that way you won't need to memorize answers to an exam, but your practical experience will be your best resource. But as for StatStuff, many folks have claimed that the StatStuff training content has helped them pass the ASQ exam (as well as exams from other training orgs). You're welcome to also use StatStuff's book that many folks love to use as a reference for what they learn in the videos ( Regardless, you can't go wrong in pulling from many different resources to learn about LSS; I recommend using StatStuff (since it's free to use) and then for any gaps or for further study on any particular tool or topic, then just Google it for many other resources that may help you.

    Finally, if you haven't already seen it, I recommend you check out a comparison between all other LSS training organizations ( This is the ONLY source that compares dozens of training orgs to let you easily see which one(s) best fit your needs.

    Hi Matt,

    I am new to your site and find it extremely informative.
    I have recently completed APICS CSCP and now looking to pursue a six sigma certification from a reputed body/institute.
    I am based in Dubai and have zeroed in on ASQ.
    Will you be able to suggest how do I go about my preparation for the ASQ green belt.
    Can you suggest one book or some materials which would be comprehensive enough for my preparation for the ASQ Green Belt.
    Are the materials available on your website sufficient enough to prepare.

    Thanks in advance for your help.

    Good question, Vamshi. Since you said it will affect the output of the body shells (which I presume means leading to sub-standard quality), then I would treat it as output-related and use Six Sigma (specifically DMAIC since it's an existing process). But since you know the root cause is the oven, then Six Sigma would be moot so you'd only need to fix the oven.

    In your situation, if the body shells are meeting quality standards, but you're finding the process is too slow and not keeping up with demand, then it would be more related to the process where you can use Lean to make that process more efficient (while hopefully still attaining your quality standards).

    Hi Matt,
    In Process based shops efficiency and effectiveness are directly related, for example, if an oven in a paint shop is not working properly it will apparently effect the output of coated body shells.In most of the cases this proportionality will hold good.In these scenarios, which methodologies should we follow (Process related or output related)....???

    Alexander - thanks, I'm glad to help!
    Ahmed - thanks for checking out the site. StatStuff's content is the same you'd get from most other GB or BB training organizations, so I'm not sure why anyone would want to pay for it when it's available here for free. I'm glad you're enjoying it!

    Hi Matt.
    I responded to a linked post offering a chance to win a free access to a LSS GB course.
    this response was an opportunity for me to receive a mail from you inviting me to website.
    I register to and here I am enjoying all these free material.
    Really Great.
    Again, Thanks Matt.
    Best Regards

    Thanks for the feedback! There's often a lot of confusing info on the different LSS methodologies. This particular video is designed to simplify the general distinctions between them. However, since there's no official body of knowledge on LSS, I wouldn't be surprised if there are variances in how different orgs teach or apply the different methodologies.

    The similarity here between DMADV & DFSS is that they are both used for developing something new (as opposed to Lean & DMAIC used for fixing something that already exists). The distinction is that DMADV is intended for a new process while DFSS is used for a new product/output.

    Despite how this layout defines the different methods in terms of their purpose or goal, it's not uncommon for each method (or any roadmap for each method) to also share many of the same tools/concepts between them. These are not meant to define rigid rules or a checklist for each method; common sense should always guide the application of these methods to ensure the goal of solving the problem comes well before trying apply every step in a process that may otherwise not make sense.

    I only have limited experience with DMADV & DFSS (my projects tend to primarily use DMAIC or Lean), so unfortunately I don't have any resources to reference. But I think a simple online search can yield some valuable resources.

    If anyone else has suggestions for good DMADV or DFSS sources, then please add a comment about it here. Thanks!

    Dear Matt!

    This site is a great source of information.

    I need a clear understanding of different types of projects and corresponded methodologies next month. I've gain it.

    I have only one question:
    My previous believe was that DFSS employ usually DMADV project Roadmap, like Six Sigma employ DMAIC project cycle. In this case brick "Six Sigma use DFSS tools..."=brick "Six Sigma Use DMADV".

    Could You explain in more details how you differentiate this tools and roadmaps?


    Could You direct me to sources of additional information, where I can find detailed information on issue/

    Thank You very much in advance
