What is the chief difference between the traditional DuPont disaggregation of ROE and the disaggregation based on RNOA?

The traditional DuPont analysis includes return on assets $($ROA$),$ which includes all assets in its numerator. That means that ROA is the average return on all the assets. The RNOA disaggregation method does not distinguish between assets that are used for core operations and those that are held as investments.
