What are the guidelines in selecting a research problem?

When selecting a research problem, it's essential to consider its relevance, feasibility, and originality. The problem should address a gap in existing knowledge or practice and be manageable within the constraints of time, resources, and skills. Additionally, it should align with your interests and expertise to maintain motivation throughout the research process. Engaging with existing literature and consulting with mentors can also help refine the problem and ensure its significance in the field.
