(Make-to-Order, Make or Buy)
"Make-to-stock" stands for the principle of producing goods so that they can be stored and delivered immediately with the next customer order. This is intended to shorten delivery times.
In contrast to this is the "make-to-order" principle, which means flexible contract manufacturing. In this case, production only takes place once an order has been placed. This usually makes sense in industries where individual products are manufactured.
Make or buy means that consideration is given in each case to whether an order is to be executed itself or whether it is to be outsourced to third parties. For this, order size and production costs usually play the decisive role.
