The DuPont ROI Model is a tool that helps businesses and organizations to assess the return on investment (ROI) of their marketing activities. The DuPont ROI Model has been around since the 1950s and it has evolved over time. The model was originally created by the DuPont corporation in order to assess whether their marketing efforts were worthwhile or not. The model is a three-step process that starts with identifying the business objectives, then determining how much each objective contributes to the overall business goals, and finally, estimating what impact each activity will have on those business goals.
