2. Product selection
where to draw the push-pull boundary in the supply chain has a strong impact on what product portfolio can be offered.
e.g. if finished products are made-to-stock and kept in a central inventory until a customer order arrives, then it may not be possible to meet the demand for all types of product configurations.
On the other hand, if the push-pull boundary is at the assembly operation, as it is in the Dell case, it is possible to offer a greater variety of products.
