What term refers to products being in stock and arriving on time?

The term that refers to products being in stock and arriving on time is "Availability." This concept highlights the importance of having the right products accessible to customers when they need them. Availability ensures that businesses can meet customer demand efficiently, enhancing customer satisfaction and loyalty.

Availability encompasses both the presence of products in stock at various locations and the timely delivery of these products to ensure that they reach customers as expected. This involves not only maintaining adequate inventory levels but also optimizing the logistics surrounding the supply chain to minimize delays.

Other terms in the choices relate to different aspects. For example, reliability typically refers to the consistency and dependability of a service or product, whereas sustainability focuses on environmentally friendly practices. Inventory management deals with the processes involved in overseeing and controlling inventory but does not specifically address the aspect of timeliness of arrival or stock presence as directly as availability does.
