A comparing and contrasting diagram can also be used as an evaluative tool. To make accurate assessments about a given topic, you must first understand the critical points of similarity and difference. Many workplace assessments use a comparing and contrasting diagram as a primary tool. You've probably reached and contrasted yourself to your coworkers. Through comparison and contrast, employee advancement, pay raises, hiring, and firing is all done. Companies, departments, or individuals could be evaluated using comparison and contrast. Similarly, to concentrate on the comparison, choose two subjects that appear unrelated at first. You would not choose two apples or two oranges for a comparison essay because they already share many properties.
