Preliminary research should help the researcher to 

1. Identify the Topic and get a better understanding

Preliminary research should help the researcher to find answers to questions such as: “What is the problem?”; “Why does the problem exist?”; “Is the problem important?”; and “What are the benefits of solving the problem?”
