Determine the Purpose

Start by asking yourself some questions: 
1. Why am I writing this? 
To answer this question, you should determine: 
> What specific information do I require? 
> Do I need to explain known facts? 
> Have I been asked to analyze a situation or recommend a particular line of action? 
> Do I need to review a course of action? 
2. What do I want to achieve? 
To answer this question, you should determine: 
> Is the report meant to generate an action? 
> How persuasive should I be? 
> Do I need to come to a conclusion or make a decision about a specific matter? 
Your “Purpose Sentence”

Should new vehicles be purchased to replace the older models? (question)
