Let me get the ball rolling for you with the definition: Scientific management, also called Taylorism, is a theory of management that analyzes and synthesizes workflows. Its main objective is improving economic efficiency, especially labor productivity. :)
I am confused by your poor spelling or grammar. Is your question, "Discus, the real life example of scientific management?" Or is it "Discuss the real life example of scientific management?"
If it is the first, I really couldn't tell you how a round spinning object from an athletic field event relates to workflow, other than the faster it spins and the harder it is tossed the farther it will go. The force, if not properly controlled, might put the discus off course.
If it is the later, find an industry that interests you and follow the workflow. Since this question appears to be a homework/study question. I will not do your work for you. However I did find this link after doing an internet search for examples of scientific management that may help.
