A literature review demonstrates your ability to research. It also showcases your expertise on your chosen topic. By including a literature review in your project or thesis, you are also providing your reader with the most prevalent theories and studies on your topic, evaluations and comparisons of these studies, and gaps there may be in the literature. This helps your reading audience to understand your project/thesis better. It also makes you a more credible and reliable author.
