A critical analysis of the reasons why companies fail/go into administration/liquidation. Relevance to different

So my investigative study topic helped me to analyze and understand the critical factors and reasons of company’s failing / going into administration/liquidation. This topic seems to me very useful and helpful from the point of view of companies getting involved in the bankruptcy process. They should clearly know what the “rules of the game” are and how the process operates.
Nevertheless any study begins with difficulties and obstacles. They connect with your personal nature (I would call them internal difficulties) and material I have to find and study (external difficulties).
My internal difficulties were connected with the time which we are everybody lack of. So at the first stage I scanned some material and then created plan to have some vision of what I am going to speak about in my investigative study. External issues were connected with selection of appropriate bibliography and split the articles related to emerging economies from those one which did not.
