Q2 What are the three fundamental types of IS within organizations?
1. Calculation systems: single purpose systems used to eliminate tedious human calculations that used a mainframe punch card.
2. Functional systems: business function system that used the computer to improve operation and management of individual departments that uses mainframe, stand-alone PCs, and networks and LANs.
3 Integrated systems: business process system that developed IS to integrate separate departments into organization-wide business processes that uses networked PCs, client-servers, the Internet and Intranets.
functional systems overcomes calculation systems by being able to do more than one thing and they didn’t have as many computer failures. Integrated systems overcame functional systems because functional systems cannot integrate separate departments and integrated systems of course can.
In my career I will probably have to deal with functional systems the most because it deals more with business functions. A problem I can see arising with functional systems in my career is well, since purchasing influences inventory, which influences production, which influences customer satisfaction, which influences future sales–then if something goes wrong with my functional system then I would find myself in big trouble. So much depends on it.
Will there ever be a system that is one up from the integrated, cross-functional systems? How would it be more advanced? What else would it do?
