rather they are the consequences of the activity being performed. The purpose of driver identify is to reveal the root causes. Thus, driver analysis is the effort expended to identify those factors that are the root causes of activity costs. For example, an analysis may reveal that the root cause of treating and disposing of toxic waste is product design. Once the root cause is known, then action can be taken to improve the activity. Specifically, creating a new product design may reduce or eliminate the cost of treating and disposing of toxic waste.
