How to manage flow of information in an essay

Hi all,
I am looking for a tool or technique to help me manage the flow of information in my essay. As the essay has many pages and much information, I need to increase the visibility of information and flow in order to ensure that I am building up informaiton (requirements, recommendations, and solutions) in consistence with the problems, objectives and rationale which I established early in the essay; so that no conflict exists throughout the essay.

Thanks

if you are willing to write an essay for IELTS you should follow 4 paragraphs: introduction, two paragraphs of giving reasons and examples for your opinion, conclusion

in first paragraph you'd better mention the general idea or a background around the topic and very briefly cite your opinion
if it is argumental essay, you need at least two main reasons in two separate paragraphs to prove your idea (usually you have to follow one side but it's better that write about the other side in just one sentence, so that your essay would be more comprehensive and developed)

if it is discussional essay you should write advantages or fors in one paragraph and disadvantages or againsts in the other (make examples if it's possible)

in conclusion paragraph you need to sum up your idea and if it is possible forecast the future of the given trend or situation

Additional Details

This is not about IELTS or a computerized Information System but it is about an academic business and management essay carrying out in Office Word. I mean tools or techniques like Mind Map or diagram-based tools like an appropriate kind of Flow Chart or if any other effective approach. I am looking for ways to control coherency in my information word document.
