    How Standardized Are Lean Six Sigma Methods?

    Someone asked me recently if the Lean Six Sigma methods are really standardized globally. This seemed to be an incomplete question. I wanted to know about the intent. The revised question I got was - Can people get different results if they are using the same information and the same assumptions? My answer was - yes, and no. Methods are standardized to a large extent. People may or not get same results depending on the chosen method. The answer is yes for many statistical analyses for given data sets. Once a statistical method is chosen, the results obtained by different users making use of same data-sets are likely to be same. Let us consider some examples showing how such statistical methods are standardized by ISO. The list below highlights a few important ones. (there are many more) Let us assume you are trying to assess the average turn-around-time for a process using some sample data collected for a limited time period. There is an international standard for this and it is named ISO 2602:1980 If you wish compare average performance before and after a particular change, you may like to use ISO 3301:1975 If you want to know whether data capturing mechanism is reliable and shall provide trustworthy data, there is ISO 10012:2003. For detecting and treating out-liers in your data, there is ISO 16269-4:2010 For risk assessment and mitigation, there is ISO 31000:2009 Not all methods provide standard results The answer to the question is NO, if it comes to qualitative methods like Quality Function Deployment, Design FMEA and the like. No two teams are likely to get same results if they use the same methods. While using ideation techniques, the objective is not to get same standard answer but to generate multiple alternatives. You may notice that even such methods are standardized. For example QFD finds a mention under ISO 9000:2000 and Design FMEA is covered under TS 16949. Lean Six Sigma methods are largely standardized. However, methods being standardized does not necessarily mean that we are likely to get same results. The beauty of lean six sigma lies in diversity of available methods. It makes sense to learn more of these so as to consider the most suitable one's for a given situation.

    Six Sigma Vs Iso

    Hi, When I discuss about Six Sigma with people of similar interests, some of them argue with me that Six Sigma and ISO are similar concepts. Both strive to achieve process improvements, and both are implementable in all the domains. Though I have argued with them saying Six Sigma is about improving a certain process by analyzing and improving it to better quality and also about data driven decision making, ISO works on fulfilling the certain best standards for a prescribed quality., my friends were not completely convinced. If six sigma is a very powerful concept, why are organizations still going for ISO ?? Pls enlighten us with the differences between the two. Thanks, Viswanathan.

    QMS, EMS Implementation

    Hye One of the most common questions I ve been facing is why is the Quality Assurance function held responsible for the QMS, EMS implementation and why the QMS , EMS implementation is a part of the QA Job? Pls throw some light on this fuzzy regions
  4. I have been interviewing people from the construction industry for my thesis to see whether six sigma can be implemented in construction industry or not. All the companies I interviewed are using ISO 9001:2008. When I explain six sigma and how it works, they always say that it is similar to ISO 9001:2008, the question here what the difference is and if they are similar, why it is not used in the construction industry. your answers are highly appreciated
  5. Hi All, How can i differenciate ISO, CMMI and Six Sigma between each other by their 1) primary & secondary Objectives 2) Methodologies 3) Certification process I have gone through many documents and processess but i hardly able to explain the same to a layman since i'm not an expert.
