Make "right" the choice! The status of direction of application deyelopment. Go from anform to engineering! Spadab is engaged in deYelopment of new basic systems for nordic saYingsbanks. 'Characteristic for these systems is modularization at a high level (building blocks).· These principles gi\'es the dirrerent banks possibilities to create their own unique products from the new basic systems and own-developed systems.
