12th Commandment of Business Writing: How to write long reports

But I've never written anything so long! Well there is a first time for everything so suck it up this has to be done.

Long reports need to completely cover all the topics you wish to recommend, and as such they are going to be long to fully expound your ideas. The parts you need to cover are simple:

Introduction
Background
Body
Conclusions
Recommendations
References
Appendices

Writing them may not be as simple. To write an effective report make sure that you write as much as you can as soon as you can. Also, you need to spend most of the time writing on sections that support your recommendations. This does not necessarily mean spend most of your time on the recommendation section itself.

You want to write each section one at a time in order to devote full attention to your current section and fully develop your ideas. Anything that supports your recommendation should be included and any supplementary info should be paraphrased and cited.
