Software can't tell you how to beat the competition, but it can determine which products and services have the greatest profit margin, who are the most productive employees, or how many pairs of socks customers buy when they purchase particular styles of shoes. Knowing this information helps you make the right decisions to adjust the product mix on your production line; retain and promote the best employees; or put certain shoes on sale. Having accurate, timely data takes the guesswork out of the decision-making process.
