(MTO / BTO / ATO)
MTO, BTO and ATO describe slight variations on the same manufacturing concept – make a product after receiving a confirmed order. This is in contrast to the make-to-stock concept, in which production is scheduled to achieve target stock levels. MTO/BTO/ATO is most common for products which are customized, but may also be important to reduce waste or handle fluctuating demand. In general, customer lead times are higher for MTO/BTO/ATO compared to make to stock.
