What is the best way to structure a report or piece of writing?

I have a report to do, and i have all the answers or no where to find the answers, but i am just struggling to put it all together. Are there any techniques when putting a piece of writing together, as i am just lost completely.
Answers:
this works every time..

every report has an intro, body and conclusion.
first write the body, then the conclusion (just summarize everything u've said- nothing new), then the intro (explain what u are going to say and why)

because u know what to write in the body, dont worry too much about a plan, just start writing as if it is a first draft..dont worry too much about its structure to begin with- you'll find that as u write it your draft will become the main piece, its just a matter of starting it.the rest will flow.. good luck
Write out each question followed by the answer to that question. In effect, dissect the report by breaking down each segment, followed by the answer to that segment. Does this makes sense to you?
When writing a paper, always remember, you must have the a Thesis which is the 1st paragraph, then your body, which is the 2nd paragraph supporting your thesis, and then your conclusion, your 3rd paragraph, stating if your thesis was right, or wrapping up your thesis, it can go many ways depending on the subject. Hope this helped.
Absolutely there is! I assume you are writing something very factual, not an opinion or a critical analysis and I will use an 8-page report as an example. If this is correct, there are 4 basic components when you look at structure:

1 - Introduction: this is SO crucial because it tells your reader, very briefly, why you are writing this report (i.e. what your goal is, such as 'to provide conclusions regarding the way we must structure the Swindon-Oxford bus service based on patterns of usage recorded during 2005 financial year'), how you are going to present the facts/evidence/research, and what deductions you want to present for consideration. Remember to be brief, clear and just provide a guideline for the reader. Should be at least one chunky paragraph, maybe more depending on the length of the piece. My last research paper was about 40 pages, and the intro was 3 pages.

2 - Main body: this is where you present your findings/facts/research and make your fundamental observations. It should be broken down into separate sub-sections for each specific area of research, such as 'details of the existing bus service schedules', 'record of expenditure based on a 10 trips-per-day rotation', 'surveyed needs of countryside residents of 30-45 years age group' and so on. If it is an 8-page report, keep each sub-section not longer than a page. Now you can either wrap up your 'recommendations' based on all the facts in one last sub-section within the main text, or you can create a paragraph within each sub-section to present your conclusions for each specific part of the report. Up to you. The real work in drawing you findings together will happen in the next part of the report which is the.

3 - Conclusion: here you start by saying something like 'In light of the information and findings noted above, it can be concluded that.' and progress into about 1 page (in the 8 page report) where you very simply and clearly state your recommendations as they link up to the main body. It sounds very pendantic, like you are writing for a kindergarten reader, but it must be done like this so that you never run the risk of losing the reader's train of thought. It is better 'if wrong, to be clearly wrong' than to leave the reader wondering exaclty what you were saying!! The conclusion is therefore a more substantiated restatement of what was in your introduction.

4 - Bibliography: depending on how academic your style is expected to be, this is where you list your main sources. The idea is to avoid being accused of plagiarism and to allow the reader to know exactly where they can access the same sources you used, if they want to make up their own minds.
I haven't said anything about in-text referencing or footnotes, becuase I am assuming this is supposed to be a practical kind of report, not an academic one. If you are doing this for an academic course, the convener should tell you which referencing style must be used.

I hope this helps!!
