many companies that maintain this technology as one of their core competencies see configured products, although they might have diverse characteristics, as standard products being produced in a so-called MTO process (make-to-order). The terms “nonstandard” or “customized” describe products, that cannot be completely configured and manual workarounds are needed. In general, such companies try to configure as far as possible and use an ETO process (engineer-to-order) to finalize the constructions.
