Know the Problem of the Problem Statement
In a dissertation proposal, a problem statement is a brief description of the problems that must be addressed scientifically. In a complete contrast, a problem statement may be downgraded into a customary but tall claim written in couple of sentences. The problem statement should briefly mention the leading points, e.g. what is the actual problem your research is revolving around? The section may also discuss some of the missing information that is relevant to prove your research problem and its background, and perhaps the development of the research question itself by the following particular developments in the literature review. Also, give the reasoning for pursuing your proposed research in your dissertation.
Before Knowing the Answer, Know the Problem First
A real question should answer these questions: What is the problem? This should explain why the organization is required. What are the limitations and scope of the problem stated? The primary purpose of the problem is to draw the attention of the research readers towards the problem-solving aspects. Realizing the fact that a well-state research problem happens to be the gist of your dissertation and thesis, you have to make your best efforts in this crucial section.
