Work with your chair to determine any specific instructions or guidance that he or she may have for you about your topic selection development document. Let's consider an example. In the Week 1 Project instructions, a sample topic refinement emerged by adding the subtopic "ethics" to a main topic "transformational leaders." Suppose that your abridged review of the literature discovered several statements touting the idea that transformational leaders raise the ethical values and behaviors of followers. However, also suppose that you have been unable to locate any empirical research testing the proposed relationship between transformational leaders and the ethical behaviors of followers. Accordingly, you may have located a gap in the literature, a problem, or research that needs to be conducted. Your dissertation needs to defend the existence of that problem (gap) in the literature to explain the purpose of your study
