For the search of the bibliographic documents, several documentary sources were used, the search was done in “google scholar”. We selected those documents that were related to the research, scientific articles, doctoral theses, methodologies used by different authors, to determine the selection of the literature found was made regarding the methodological quality and if they fulfill the criteria of scientific quality sought. A logical structure was developed that introduces the information in a sequential and reasonable manner, in such a way that the article is better written and allows easy reading and understanding. As a result, it can be said that there is a diversity of literature on the subject of study on which information has been collected and it can be said that there is information of all kinds and with different scientific levels, which is why there are no disadvantages regarding the existing literature for the approach of a doctoral thesis.
