One of the most important steps in developing your dissertation research project is to begin drafting the problem statement. At CTU, the term trio is used to refer to the problem, purpose, and research question as a set of three critical foundations for your dissertation project. You can find the trio in use in the template for the Research Prospectus, which is the first milestone deliverable for your future dissertation research, as well as in the CTU Proposal and Dissertation template. The trio provides the foundation for your dissertation. Research originates with a problem that will be the focus of a study, and the problem requires substantiation by the scholarly literature reviewed as part of the research.
