For your convenience, here is one approximate example of a dissertation literature review. All titles and names were intentionally developed to provide this example only.
Issues of the building of an organizational structure were covered in any academic and practical works. This subject is extremely important for a company’s development and growth. To cover all the important aspects, the basic conceptions were covered.
Precisely, current developments related to building a structure of any organization can be divided into two major groups. Smith, Jones, and Lloyds are adherent to centralization and consider that management is related mainly to control. On the other hand, Thomson, Williams, and Backer see management as decentralized and focused mostly on oversight.
However, both major conceptions fail to address the role of management in the course of natural changes in a market. Apart from covering the main conceptions, possible ways to address any kind of uncertainty in terms of the appropriate company’s management were developed in this dissertation.
Preparing a good literary review requires a lot of work. Firstly, you should identify the goals of your research and writing. Afterward, you research all sources that can be relevant to your topic. You select among such the most valuable that contain basic approaches related to your topic or identify the main gaps in it.
In your review, you address all such points along with the literature where such were described. For the convenience of your readers, you logically separate the introduction of your review, its main body, and the final part.
At the end of your work, the review should appear as a part of your writing that familiarizes your readers with all the important questions of your work and how does your literature address such.
