This document discusses what constitutes a good research problem and the criteria for selecting one. It states that a research problem should arise from a practical or theoretical issue that needs investigation. Not all problems are researchable, as some involve individual preferences or values that cannot be scientifically identified. A good research problem should not be too vague or narrow, provide an overview of the subject, and make a general concept more specific. It also notes that a research problem must have an empirical basis. Finally, it outlines four key questions - what, why, how, and when - that underpin any research problem framework.
