„As a long-time partner of the Sommer Informatik we use the software GLASGLOBAL® since the introduction of the DIN 18008. In cooperation with the TU Dresden we tested different Glasstatic software. As currently the only software program, GLASGLOBAL® achieved 100% of the mandatory requirements. In addition, Sommer Informatik was able to cover 52% of the nice-to-have criteria.”
