A question we are often asked is ‘how do I link my critique or literature review to my research questions or hypothesis?’ Recently, a variation of this question was asked by Will. He had submitted a first draft of his thesis to his supervisor for comment and was advised that what he had produced a literature summary, not a critical review.
When we looked over Will’s work, it became apparent that he was synopsising what had been written by others at the expense of building on it to develop his own arguments. A hallmark of academic research is that it relates to the work of other scholars and practitioners. To improve his review, Will needed to directly address his research questions using appropriate literature, while at the same time, embedding it in a critique of the work from previous researchers. Following our guidance, Will produced his own unique academic positions. This helped him answer his research questions and draw on the concepts, theories and models from others to substantiate his arguments.
Like Will’s situation, many dissertations begin with questions (who, what, where, when, why, how, or some combination of these) or hypothesis (a tentative statement, or explanation, for an observation, phenomenon, or problem that can be tested by further investigation). Prior to finalising your questions or hypotheses, you need to establish what is already known about the topic. in other words, what ‘gaps’ exist in that knowledge (that is, a critical review).
A critical review enables you to build a scaffold for your main arguments. This scaffold will, in turn, provide you with information to answer your questions or hypotheses. A well-sourced critique should help you, firstly, set the context in which your research is located. If, for example, your broad research topic is ‘supply chain management’, the critique is partially an opportunity to introduce the topic, outline its history and bring the reader up to date on the latest thinking. This should facilitate you to align your research questions, or hypotheses, to what is already known about the topic.
Secondly, the critique should aid the identification, definition and exploration of your overall research problem in more depth. Searching for, reviewing and critiquing relevant books, journals and other material, permits you to situate your specific research within the accumulated archive of knowledge already associated with your topic. This helps to relate your questions or hypotheses to queries which have already been previously posited (and answered, or partially answered). Using this knowledge-base will also enable you to highlight seminal investigations, as well as describe, debate and explain the contributions of all key authors to the topic.
Exploring further, you should be able to recognise concepts and theories that are particularly relevant to your questions/hypotheses and discover other, similar inquiries associated with your topic. This literature should allow you to link your question or hypothesis and provide input into your conceptual and theoretical framework. It may assist you to establish specific research methodologies and methods that have been used in prior investigations. Furthermore, it should assist you to formulate and continuously improve your questions or hypotheses, making them more precise and relevant.
It is likely that you will return to your critical literature review many times on your thesis journey, updating, revising and rewriting it, while considering newly discovered ideas, concepts, theories and viewpoints. As you continuously review it, keep asking yourself: ‘How does this material contribute to the fundamental purpose of my thesis?’ The answer will help you maintain your focus on exactly what you want to achieve, why you want to do it, and how you intend doing it. Adopting this approach helps provide questions that lead to answers, which, in turn, add to and enhance existing knowledge. It also means you avoid two principal pitfalls when linking your thesis literature review to your research questions/hypotheses. ‘Brain dumps’ (describing everything you know about your topic) and ’sermons’ (lecturing readers who are subject matter specialists)!
