    It is difficult to understand your question.
    My answer is as the following :
     If Six Sigma and ISO 9000 were equal. I would use ISO because  
    it is more popular. But in reality, they are not equal.
    Six Sigma emphasizes on quality improvement while ISO 9000 emphasizes on quality control.
    Normally (but not always), Six Sigma provides higher quality level.
    The advantage of ISO is it can be certified and more be reconized.
    I hope that I answered your question.

    ISO 9000 and Six Sigma are very different in structure and approach.  For the most part, ISO 9000 is “non-prescriptive”.  That is, it does not tell you HOW to do something, it just tells you WHAT you have to accomplish.  It requires that people who are asked to do a job must be qualified to do it.  It requires that you review contracts before accepting them.  It requires that you have a corrective action system.  It does NOT give you mechanisms for doing these things.
    The new ISO 9000:2000 standard has one paragraph the requires that you measure, analyze, and improve.  The very next paragraph requires that you control.
    Six Sigma is a process for actually carrying out needed improvements.  It has a roadmap, and a set of tools.
    If you properly do Six Sigma, you fulfill many of ISO’s requirements.  If you have ISO, you have an excellent framework within which to apply Six Sigma.
    We did ISO first, then Six Sigma.  Many of our Six Sigma projects involved fixing ISO processes that were less than optimum, because we did not understand Six Sigma principles when we designed them.
    My answer is that it is not an “OR” question.  I think that both are needed for world class quality.

    Pitamber, as Jaran and denton have noted, these are two different subjects, and I believe the differences have been explained well.  I would like to add one additional point, as well, coming from strictly a Quality managment perspective.  I feel that 6Sigma informs your customers that you are doing the utmost to establish and improve the quality of your product.
    However, I believe that ISO certification would need to be your first step, as (1) It informs your customer you have a management system in place, and that it has been approved by a third party process that is understood by their own people; (2) where 6Sigma is a continuing process, ISO reaches a stage of certified benchmark approval, and if your registrar is accepted internationally, it means that your system is compliant with basic expectations, certified independently, and that you are “qualified” as a suitable potential supplier.  I feel this certification needs to be the critical first objective. 
    You need to keep in mind what your customers also know that ISO certification is no guarantee of quality, only that you have a system in place by which you should be able to establish the expected quality in your product.  6Sigma can be your mechanism from there, or be developed in parallel with the ISO development.
    I hope this helps a little.  – Dewayne

    The ISO 9000 series standards define the internationally accepted minimum requirements for an effective quality MANAGEMENT system. They define requirements for the whole business process of an organization, from top management responsibility to measurement and control to listening to the voice of the customer. ISO 9001:2000 describes the management requirements in a way that they can be audited, either internally or by external parties. But it only describes the desired minimum state – it does not say “how” to do anything.
    Any organization will have many quality-related problems. An ISO 9000-based quality management system has processes to ensure that the problems are resolved. There are many tools available to help resolve those problems – to do the “how” part. The task of the quality practitioner is to determine the most appropriate set of tools and aid the organization in applying them effectively. Sometimes Six Sigma is the appropriate set of tools to use, especially in a high-volume manufacturing problem. Sometimes some other set of tools is more appropriate, especially in a service environment where every task is different from the previous one.
    ISO 9000 defines a management system.
    Six Sigma is a tool that, if appropriate, may be used by the management system.
