I am looking for a good dissertation topic about use of six sigma in construction engineering. I have a basic understanding of six sigma and I am studying B.Sc Civil Engineering in Bahrain. For me senior project/thesis/dissertation, I am looking for a topic which incorporates both six sigma and construction industry. One idea that comes to my mind is &quote;Implementing Six Sigma in Construction Projects&quote; But I don't know how and from where to start? Can you guide me here? How would I go about conducting the research? Thanks!
