Hi,
We all are aware of the importance of quality aspect of six sigma,why is that not every company is making six sigma a mandatory phenomena?People who lead an organisation/MNC/PSU's etc are well aware of the Six Sigma concept,particularly a scenario like this where all the companies are going for cost cutting,still management is not making six sigma mandatory concept.
Is this due to the cost involved ,or time consumed in implementation or modification required in methodology of six sigma?
