From "order placed" to "stocked on the shelf", lead time decides how much inventory you must hold. Count the days between two dates, get workdays, and plan your reorder point.
See both the raw gap and the Monday-Friday working days.
ROP = daily demand × lead time + safety stock — the number that prevents stockouts.
