In addition, a case study is presented to demonstrate the application of such methodology and its effectiveness on the production process. To assess your understanding of the author point of views, read and answer the following questions:1. Refer to the article, in brief, explain the DMAIC stages implemented during continuous improvement projects (six – sigma)? (150 – 200 words).2. To what extent do you support the improvement propositions for machine Kolbus BF511 process mentioned at the case study? Explain. (200 – 250).3. From your point of view, discuss the efficiency of using six-sigma methodology at Saudi Arabia` industrial enterprises. (200 – 250).
