Final answer:
The advantage of using ROI as a performance evaluation method is that it can be decomposed into profit margin and investment turnover.
Step-by-step explanation:
The major advantage of using ROI as a performance evaluation method is that it can be decomposed into two meaningful parts: profit margin and investment turnover.
Profit margin represents the percentage of profit obtained from each unit of sales or investment. It shows how efficiently a company is generating profit from its operations.
Investment turnover, on the other hand, indicates how effectively a company is utilizing its assets to generate revenue. It measures the amount of sales that can be generated from each unit of investment.
