Return on Investment (ROI) also known as Return on Assets (ROA) is known as the broadest measure of profitability as it takes into account how well a company used its assets to generate profit (net income). However, it is often argued that net income may not be sufficient to measure a companys profitability. Therefore, the development of the DuPont Model was established. Discuss thoroughly the premise of the DuPont Model in comparison to ROI/ROA and if either measure of profitability is more advantageous than the other.
