The research process is not linear. As you begin your research and develop your topic, you will encounter new information that will create new questions. This is a normal part of the process.
Your research question will guide your research, determining what type of sources you need, and the concepts you need to explore. Your question may change as you discover new aspects of your topic, and you may need to repeat parts of the research cycle.
Once you identify a research question or thesis statement (problem definition) it's time to deconstruct it. Look at your question or statement and identify what the main concepts are.
