Focus of the review:
The literature review should not be a general, leisurely browse through a number of human resource management texts. It is, rather a focused study designed to extract information of direct relevance to your project. You do not have the time to read everything about the subject area, so you need to concentrate on those texts which provide the information you need - and to know what information you need, you have to be clear in your initial thoughts about the subject.
As your reading of the literature continues, you should be thinking more and more about the precise definition of the problem or issue. This will make your selection of texts, and your study of them, increasingly focused on the final topic for investigation.
