However, all the members of the dissertation committee have several common purposes. And this article is aimed to discover the secret of the dissertation committee’s purposes.
 
So, the members of the dissertation committee have the following purposes:

• The members of the dissertation committee evaluate student’s intentions about his or her future research (these intentions are normally described in a dissertation proposal), and decide whether this research deserves being conducted or not. This prevents a student from conducting useless and hopeless researches (hence, from wasting students’ efforts).

• The members of the dissertation committee also help a student prepare his or her dissertation, conduct his/her dissertation research, design a dissertation correctly, and the like. To cut the long story short, the members of the dissertation committee render a student their assistance in preparing a dissertation.
• The members of the dissertation committee evaluate students’ works at their dissertation defense. They make sure that a student prepared a dissertation on his or her own; evaluate the dissertation’s quality, and the significance of the research results.

So, you may turn to the members of the dissertation committee any time you face some difficulties in preparing your dissertation.
