Which of the following measures is an example of inventory performance?

The measure of inventory performance is best represented by the rate of stock turn. The stock turn rate, or inventory turnover ratio, assesses how efficiently a company manages its inventory by measuring how often inventory is sold and replaced over a certain period. A higher rate of stock turn indicates effective inventory management, suggesting that products are being sold quickly and that excess inventory is minimized. This performance measure is vital for understanding the company's operational efficiency and financial health, as it ties directly to sales and revenue generation.

Other measures such as employee satisfaction surveys, product development time, and market share growth do not specifically relate to inventory management. Employee satisfaction surveys focus on the workplace environment and staff morale, which, while important, do not directly assess inventory performance. Product development time pertains to the efficiency of bringing new products to market and does not measure how existing inventory is managed. Market share growth relates to a company's position in the marketplace and overall sales effectiveness, rather than how well it manages its inventory levels. Thus, the rate of stock turn specifically provides insights relevant to inventory performance.
