Writing a report

Sometimes we need to write a report and the only thing we do is to write ideas with no sense.
Reports are used by another person or group of people, they're often used to help them make decisions. The information always has to be clearly presented and easy to access, most of the times it includes suggestions, recommendations and conclusions.
 Some examples are:

1.  Financial situations of a company 
2. Evaluating the facilities that a place has to offer.
3. Scientific results.
