I was especially entice by how the literature review is an essential part of a research process and a key component of dissertational process. It informs what is known about a research topic and what might benefit from further exploration (Creswell, 2009). One such strategy is to understand the mechanisms, or pieces, of the dissertation and their purposes before you begin writing (Creswell, 2009).
