If a report sounds like waffle and jargon...

... it often means it is just waffle!

• Do you read reports that splash long, complex sounding, words everywhere?
• Do they seem to make no sense?
• Do they sound like waffle?

If you answered yes to each one of these then the author probably is waffling, and has nothing useful to say.

A useful report will have clear conclusions (and recommendations).  It demonstrates that the author is confident in that subject, and has discovered new knowledge.

Tips: 
Check the report's abstract, and if it makes sense then check the conclusions.  If the conclusions are interesting and relevant then read the report; else don't bother.

Write reports in plain english. 

Be clear about your conclusions and recommendations.
