It is an interesting topic, as Enron has often been studied in terms of the complications it posed for the economy, investors, and accounting law, but not so much as an organizational breakdown of communications (at least not so far as I am aware). In terms of the length of your project, you have posed many questions to answer, but your hypothesis seems concentrated enough to keep you on 'track.' Also, all of your questions have a single focus, which is good. Selecting one theorist and theory to apply to a very complicated situation seems ideal, given the extensive literature that is available on Enron.
Of course, because your paper is just in the draft stages it is hard to critique your writing style, but your outline seems comprehensive,...
The only questions to ask are if you will be able to obtain enough information on the interior, communication processes going on at Enron to do your analysis, as you did not include a literature review. You may need to think about how to balance giving an introductory history to Enron, before launching into a discussion of the particular issue that is of interest to your research. Also -- will you focus on any particular actors or use specific situations to dramatize the events? You don't have to, but this is just something to think about. You may also want to include a 'lessons learned' section for readers, to show how they may avoid replicating the difficulties of Enron at their place of work. Great proposal!
