Measures of market performance, such as sales and market share, are backward-looking measures of success or failure.
Step-by-step explanation:
True. Measures of market performance, such as sales and market share, are backward-looking measures of success or failure. They provide information about how a company has performed in the past and indicate its market position. For example, if a company's sales have been declining and its market share has been decreasing, it may indicate that the company is not performing well in the market.
