You made some interesting points about the use of the DuPont analysis and how it can be used to identify issues causing a drag on shareholder equity. As you said, if a company does determine where the problems might lie then they can focus their efforts on improving that area. When things are going well the company may just enjoy the profits and not worry about problems or issues in the future. You don't always want to seem like the executive looking for the problems. So how would you balance focusing on the problem areas while still growing the positive components of the business?
