If the delivery of an item is delayed or the consumption rate increases rapidly and unpredictably for any reason, the safety stock will cover the shortage of items.

If your suppliers supply raw materials on time, your production process does not disturb you. Now we use historical data to determine the standard deviation of lead time. Over time, it may be necessary to make adjustments to your ROP as a result of shifts in demand, lead time, or safety stock requirements. This system monitors your inventory levels and orders more when the level drops below a certain point. Reorder points typically include safety stock, as demonstrated in the previously discussed formula. Even if it is not explicitly stated, it is advisable to incorporate some allowance to account for unexpected events.
