Days Inventory Outstanding (DIO) can vary significantly across different industries. Companies that sell perishable goods or have high inventory turnover, such as retailers or manufacturers, typically have a lower DIO compared to industries with slower-moving inventory, like automotive or aerospace. Analyzing a company's DIO in the context of its industry peers can provide valuable insights into its inventory management practices.

Explain how Days Inventory Outstanding (DIO) is related to other working capital metrics, such as Days Sales Outstanding and Days Payable Outstanding, and how these metrics can be used together to assess a company's cash conversion cycle.
Days Inventory Outstanding (DIO) is closely related to other working capital metrics, such as Days Sales Outstanding (DSO) and Days Payable Outstanding (DPO), as they all contribute to a company's cash conversion cycle. The cash conversion cycle measures the time it takes for a company to convert its investments in inventory and other resources into cash from sales. DIO represents the time it takes to sell the inventory, DSO represents the time it takes to collect payments from customers, and DPO represents the time it takes to pay suppliers. By analyzing these metrics together, companies can identify opportunities to optimize their working capital management and improve cash flow. For example, a company with a high DIO and DSO but a low DPO may need to focus on improving inventory management and customer collections to shorten the cash conversion cycle and free up working capital.
