Tasks in Global Information Systems Design
Critical tasks in the design of Global Information Systems are- Process and System Design: How are the processes between distributed actors organized, how are the systems distributed / integrated.
- Technical architecture: What is the technical infrastructure enabling actors to collaborate?
- Support mechanisms: How are actors in the process of communication, collaboration, cooperation supported?
A variety of examples can be found - basically, every multi-lingual website can be seen as a global information system. However, mostly a GLIS is referred as a specific system developed or used in the global context.
Examples
Specific examples are- Systems developed for multinational users, e.g., SAP as a global ERP system
- Global Information Systems for Education: The Global Learning Objects Brokered Exchange
- Support systems for global cooperation: Systems, e.g. Palantir
