Because you’ve weeded out the worst and mediocre, you can take advantage of the fourth reason, which is that you can find the systems most suitable to your type of business. Have your list of requirements ready and check them off as you go through the review. Does a vendor mention gamification, but the reviewers consistently ignore the subject? It may not be all that the vendor cuts it out to be. Security options seem lacking in the reviews, or a reviewer mentions a hacking incident? Move on to another system’s reviews as quickly as you can. All this reading is important because it presents an unbiased view of the systems’ tools.
