UNDERSTANDING THE SIX SIGMA CONCEPT

even after two days of prestudy work on six sigma, i still harbour lots of questions.

what does six sigma really mean? is it more of a process redesign and improvement tool than a problem solving tool?

how effective is six sigma applications?

from our cbe module we know that for every new innovation in an organisation, there will be some employess and management leaders who are resistant to change and they have a strong conviction that things are very perfect as they are since it’s the approach that has brought them thus far. how challenging would it be to use six sigma to change the mindset and processes which organisations have built their results overtime?

if the sopk which comprises of systems thinking, variation, theroy of knowledge and psychology produces results, why would we want to change those results? referring back to wat jan gillet said about theory of knowledge, that a comon word doesn’t mean the same thing to everyone. for example everyone has a different way of veiwing what is acceptable, very acceptable, unacceptable and very unacceptable. if all this terms produce results in their different capacities, so then how can we measure, improve and control the changes which the different results produces?

    From my understanding, i don’t think that 6 sigma is simply a problem solving tool, rather it is a concept that employs the use of processes such as the DMAIC as well as tools within these processes to reduce business costs via a reduction in variability in business processes. I believe it is more holistic than simply being a problem solving tool.

    As to how effective it is, well literature seems to suggest that a high number of organizations have indicated that they have had success upon the correct implementation of the 6 sigma concept.

    As to your last question, I think that is where standardization is key. There has to be a generally accepted definition off what is acceptable and what isn’t based on carefully measured parameters.
