What does a decrease in lead time generally imply for customer demand uncertainty?

A decrease in lead time generally implies a reduction in customer demand uncertainty. When lead times are shorter, a company can respond more swiftly to changes in customer demand. This agility allows businesses to plan better, adjust production schedules, and replenish inventory promptly in response to actual demand.

Shorter lead times enable businesses to operate with more precise data regarding customer preferences and buying patterns, ultimately leading to improved forecasting accuracy. This responsiveness reduces the need for companies to hold large amounts of inventory as a buffer against uncertainty, decreasing the overall risk associated with fluctuating demand.

Conversely, increased lead times create a wider gap between customer orders and the time it takes to fulfill these orders, which can heighten uncertainty by making it more challenging to predict and adapt to shifts in demand. Therefore, the correct interpretation is that a decrease in lead time does lead to a decrease in uncertainty regarding customer demand, enabling a more fluid and responsive supply chain operation.
