Integrated digital manufacturing, product design, simulation...
This purchase completes the picture for Siemens, who will now be able to fully represent and manage a product from conception through end of life. Manufacturing, service, design, code, electronics, etc...

Integration, one single source of truth, team collaboration, global engineering all deliver very serious efficiencies when compared to discrete solutions, not unified in the way Siemens is doing.
