Your report is done. The hard part is over. You just need to tie up the loose ends. The abstract, a short, condensed version of the work, is a big part of it.
Before you can write a good abstract, you’ll have to know what qualities an effective one usually comes with.
It can stand on its own. A well-written abstract can stand on its own merits. When someone reads through it, they’ll understand exactly what the piece is about – no more and no less. Of course, it should be readable, so put it through a good English grammar software.
It follows the report’s chronology and structure. Abstracts should follow the order of the report, from the introduction to the body down to the conclusion. It makes it read more like the report, effectively preparing the reader for what to expect.
It strictly summarizes the report, adding no new information. The abstract is a preview of the report, not a real part of it. As such, all information included in it should be drawn directly from the material, with no unwarranted extras.
It provides all important topics, with logical connections. While you obviously can’t make it as detailed as the real report, your abstract should feature all the major topics it covers, leaving no pertinent details out.
