    Default Six Sigma certification

    HI All

    I need to delve a bit deeper into six sigma and was wondering if there is anyone with some experience in this regard...

    Is there a reputable online certification program that one can follow?

    Thanks

    If I delve back into my manufacturing days with a UK corporate and if my memory does not fail me.

    Six Sigma was merely one component of LEAN Manufacturing. It would be difficult to implement Six Sigma without having the other disciplines under your belt. Kaizan, 5S's, Kanban, Pull Production etc. You may have to do other training first. A quick google brought this up. http://www.sixsigmasouthafrica.co.za/

    Google Lean Manufacturing Black Belt, this will get you closer to where you want to be.

    We found that we could not implement Lean manufacturing in our plant, machines to old, raw materials not good enough and working culture was wrong and could not be persuaded to buy in. So we selectively instituted elements of LEAN.

    Good luck on your journey

    I have to agree, six sigma has its place but is pretty useless without the other considerations mentioned above regarding broader system. Most importantly the systems thinking paradigm which could be more effective in various scenarios, which should by default in today's age consider TOC too IMHO.

    Not sure about the certification part, but there is a lot of content on Udemy.

    I did my training through TLC in Pietermaritzburg (https://tlc-global.com/all-courses/), certification was done by Acuity (https://acuityinstitute.com/) in the US. It was a combination of classroom and e-learning.

    Six Sigma is an expensive American commercialisation and packaging of basic principles and math that have been around for ages. I use the math almost daily particularly correlation and multiple regression analytics which Six Sigma packages as 2k3v Design Of Experiments (DOE).

    Granted, the framework and process punted is logical and works but the Belt System of grading is BS.

    The formula Y=f(x)e is central to Six Sigma where Y is the dependent variable or output, f is the process and x is an independent variable within the process that affects/results in Y.

    The basic process is: 1) Identify and quantify variation; 2) Identify the independent variables that result in Y (correlation analytics) and; 3) Identify an quantify numerically the effect of each independent variable on Y as well as the effect if these independent variables interact. (multiple regression analytics or 2k3x or DOE)

    The outcome is a solution that allows you to adjust each independent variable to generate the result you require of Y.

    (Pictures below)

    What is great about the multiple regression is that once you have identified the independent variables and their effect, you can model these solutions on a computer without having to adjust the actual process and wait to see if you have been successful or not.

    But to become a ''Black Belt'' Six Sigma operator is hellishly expensive when you can just learn the basic math

    The three math aspects of variation, correlation and regression can be used effectively outside of the Six Sigma process and these become more powerful when used with a Systems Thinking approach when establishing relationships between independent variables.

    Below is an ST model of an actual client's logistics operation and in this project TOC played a major role in the solution, particularly starving a constraint. The model represents the relationships between the elements of the logistics business plus the manufacturing, sales and other functions. The so called Six Sigma math was used identify and quantify significant independent variables that were contributors to logistics costs. The net result was a reduction in logistics costs of @ R390mio in the first 12 months, transporters reduced from 200 to 20 and the dropping of 12 additional warehouses in peak season along with related warehouse and staffing costs.

    Once I had mapped the relationships I used the math to analyse the connectors between the nodes and quantify, in monetary terms, those relationships.

    Its a fantastic means of identifying obscure but significant cost generators or ''waste'' in a business.

    Thanks for all the feedback...

    What I am taking from this is that Six Sigma is essentially more of a measurement tool (?) and it has to be used with either something like LEAN or TOC to obtain the best possible results..?!?

    I am possibly off target...

    Christo, 6S is a process methodology which consists of a number of tools. These tools can be deployed outside of 6S and you dont necessarily need to use Lean or TOC.

    As mentioned in my previous posts, I use some of the concepts/tools for identifying variation, establishing relationships and quantifying these relationships, daily and successfully without having to use the complete SS process. From time to time, I use other tools such as TOC should the project require it.

    What you need to understand is that 6S has become a commercial package costing an arm and a leg to get certification and then you need to renew certification annually where the tools such as the analytics components are widely available and have been way before 6S.

    So from my perspective, do I need to be or hire a 6S Black Belt? No, do I need the analytical skills? Yes.

    PM me so we can chat off-line about why you feel you need this.

    if i remeber correctly excel has a stats add on that will run decent regression, correlation, variace etc.

    play a little and you will be able to go a long way to measure and analise most processes.

    I agree with Estee, lots of buzz around.

    lean = reduce waste

    6sigma= reduce variation
    Both attempt cost saving = improved profit !
