Your research question (RQ) must concern a substantial issue that can drive every part of your research agenda. RQs typically arise either from your reading and/or from a lecture or presentation about a specific topic.
In a business research project, you should develop one single researchable question and no more. A common feature of the small student projects that fail is that many RQs are posed, often beyond the scope of what you could hope to achieve with the time and resource at your disposal.
You also need to ensure that how the RQ relates to your literature review is made clear. If the connections are unclear, examiners find that students do not answer their own RQs, and their answers fail to add meaningfully to the chosen literature.
Open and uncomplicated RQs that begin with ‘What … ?’, ‘Why … ?’ and ‘How … ?’ are preferable to closed, yes/no questions that limit respondents’ answers. Good RQs may also be included as part of the title of your report: the title then suggests the article’s argument and substance.
