Greater commonality of a component SKU with respect to various finished product SKUs is a desirable objective in operations, since it increases the product’s range flexibility with respect to these finished products but not the volume flexibility.

The “JIT in the supply chain” focus in JIT manufacturing leads to having a limited number of suppliers for each SKU as a result of rigorously selecting only those suppliers that offer the highest level of excellence.

Saunder’s Bakery of Pancakes uses a weighted moving average method to forecast pancake sales. It assigns a weight of 5 to the previous month’s demand, 3 to demand two months ago, and 1 to demand three months ago.
