    Hi Paul,

    SIPOC – Supplier, Input, Process, Output, Customer is based on a project mangement technique for determining all the things that need to be done to complete the project and the order in which they need to be done. The core of it is IPO, you start with the process; “Prepare a report.” You ask, “What inputs do I need in order to create this report?” In all liklihood, those inputs are the outputs of one or more previous processes. The output of the “Prepare a report” process is the report itself, which, in turn will form the input for yet another process, say, “Give a presentation.”
    The supplier is that activity from whom you obtain the inputs. The customer is that activity to whom you deliver the outputs.

    Hello Paul,

    Peter Scholtes created the SIPOC model to help educate organizations on “Customer In” thinking. Mr. Scholtes is a world-renowned consultant. It is based on Dr. Deming’s “View of a System”. Traditionally with the use of the Western Management Philosophy, a “Product Out” mentality is used. Basically, this means that the organization knows best what the customer wants and not the customer. As anyone can see, this is not true (entirely, anyway).

    You may find his book “The Leader’s Handbook” at Amazon.com. This is a tremendous book, one you will likely read several times through. I rate this in my top 5 books of all time.

    Best regards,

    Kevin

    Your input is very important for my self, does any body know what is the concept of Sipoc, supplier-input-process-output-customer,
    If you can recommend some books of references will be GREAT !!!

    thanks in advance

    Thank you Kevin, I’m going to read that book and may be we can comment in some few days.
    By the way what is your point of view about this tool sipoc, is this something to use in any 6S project or may be for those under certain conditions ?, do you know how popular is this on the project development?

    THanks Paul

    Hello Paul,

    I look forward to discussing this book with you and others here. You will find the SIPOC model discussed in Chapter 3 of his book.

    I would say that SIPOC and Six Sigma could be used together. The SIPOC model works backwards, working right to left and starting with the “C” for customer. Identifying the customers in your customer chain is an important first step. Here you will identify the Critical Characteristics that will need to be achieved in order to deliver high quality products or services. You will need to monitor the inputs and the processes used to achieve the desired outputs (the “O”). To do this, many of the quality tools found in the Six Sigma plan (Kaizen, TQM, Lean, whatever) can help to review the inputs, trouble shoot processes, monitor processes, and establish control plans (the “I” and “P”). Where the Critical Characteristic is a life or death characteristic, for me, this is where operating at a Six Sigma level is paramount. Here, cost is secondary and safety is primary. Cost savings are in general, an ancillary benefit. The Six Sigma tool must be fairly and honestly applied.

    I like the SIPOC model and use it to explain Dr. Deming’s “View of a System”. Dr. Deming’s “View” isn’t as recognizable to the average person as I think the SIPOC model is. I’m not the one to speak about how well Six Sigma addresses the System’s View if in fact it does at all. For that I need to refer this question to someone in this forum with better practical knowledge of Six Sigma. As for how well SIPOC would work for Project Development I am not sure I am clear what you’re asking specifically. Perhaps you could offer more detail in your next post so that I could consider it in a better context.

    Regards,

    Kevin

    From Joe (MBB)

    SIPOC is one of my favourite tools. Very nearly every DMAIC (six sigma process improvement) project I have coached has benefitted from doing a SIPOC.

    SIPOC represents on one page the key parts to the process operation. Traditional coaching says start with the C and work right to left. I happen to start with the P, then O, then C… then I and finally S. (Whatever works for you.) So this gives you a clear, high level view of all the elements involved in doing that process from start to finish.

    Now where it gets interesting is in the relationship between I/P and O. Once you have determined the elements in the SIPOC, ask the customer how they define ‘critical to quality’ for the O. Then baseline how consistently and well you deliver that level of quality.

    The next key step is to understand what variables in I and P drive the quality in O. Focus relentlessly on improving and controlling the I/P variables. The ultimate end-state is that you do not need to measure quality in the O, because you can predict it by the measures of the I/P variables.

    I would be interested in hearing about Kevin’s life or death scenario.

    Hello Helen,

    I once worked for a medical device manufacturer. I recall the mantra given the inspectors at that time was, “The patient is on a operating table. Do your inspections!!” The feeling was that if we inspected hard enough, we would eliminate the defects from reaching the Customer. There was a much less expensive means to this end.

    Process Controls and robust designs to me are better solutions. Running the process to a six sigma level is what the customer expects (for that matter, so doesn’t the patient). Here, running to generally accepted +/- 3 sigma level is insufficient. It would lead to expensive litigation for the hospital. In addition, I would suspect other industries, automotive, aerospace, and defense might practically need six sigma levels of quality.

    Regards,

    Kevin

    Kevin, I appreciate your comments, let me explain for you and other what is my possible confusion with this tool,
    is this something to apply at the beginning of any project?
    I heard helps to improve the focuss on your project, is that true ?
    why we should use this and not other tools ?

    You know, I certainly need to read that chapter, let me get the book and we will share some comments.

    WOULD SOMEBODY HAVE SOME EXAMPLES TO SHARE ?????

    Regards, Paul

    Here is a book that covers SIPOC,
    Rath and Strong’s Six Sigma Pocket Guide.
    It should be available from Amazon.com.

    Joe, I have seen some diagrams of SIPOC, but something that is not clear for me is, how define the process ?,

    can you help me to understand this for me ?

    in a project how do you define the process ?

    tks

    Paul,

    I recommend ‘The Six Sigma Revolution” by George Eckes.
    This book is a good read and written in such a way that anyone can grasp the idea. By the way w/SIPOC you start with the ‘C’ customer, generate CTQ and work back.

    regards, M

    SIPOC is basic to identify the process loop holes which are to be attacked first to solve the issue.
