ICT Infrastructure and Application Portfolio
ICT Services are built on the ICT Infrastructure and Application Portfolio. The ICT Infrastructure Portfolio should serve as a solid foundation, enabling new applications to be rolled out quickly.

These mainframes had to be fed with punch cards that took days or weeks to “program” and which had to be entered into the computer in a small available timeslot. CPU usage was extremely expensive, hence off-line programming and extensive preparation of the program via the Waterfall method. The only available bullet had to be on target.
