Analyze your aim and audience. When writing, limit yourself to answering one question. This will be the aim of your writing. If you know who you are writing for, their interests, knowledge and motives, you will be more successful when addressing them.
Research your topic. The information you will be collecting supports your content. This will make you more knowledgable on your own topic.
Build your argument and support it. Remember, you are writing to persuade as well as for delivering information. Use your research to build a logical argument and identify any fallacies in the argument. As you are trying to convince someone, others are trying to persuade you.
Organize your thoughts before writing. After researching, don't rush to write your draft, but take some time to think about the outline of your paper. A good outline connects one point to another, so that the audience can easily understand what you wrote.
Write the draft. This would be easy considered you have the information you need. Try to connect to the reader and make what they will read understandable. Avoid jargon, and go right to the point in the first paragraphs. As people may have not time to read the entire paper, summarize the main point in the first two paragraphs. Summarize your main points in the conclusions.
Edit your work. You can start from the structure or spelling and punctuation, but remember who you wrote for. Critique your work objectively. As writing requires creating something new, editing demands high criticism.
Ask for feedback. What you wrote may need to be checked by one of your superiors, so it is advisable to ask someone to evaluate your work beforehand.
