In order to look at the trends in information systems it is important to firstly look at what is an information system and what value does it have in modern organisations. Information Systems are a combination of people, data , process, information technology and information presentation and these elements interact to improve all aspects of an organisations . Information systems play a vital role in all organisations, from a day to day basis using Transaction Processing Systems to strategic level decisions using an Executive Support System(ESS). Information systems are commonly used to achieve competitive advantage, secure customer intimacy, for improved decision making, to try out new models/products and for more or less survival in a modern business environment.
The role of information systems are now changing an there is more of a focus on customers as opposed to internal business procedures. Information systems are also now used in numerous different industries in order to improve efficiency across many sectors. For example, information systems are used across the health sector including Hospital Information System(HIS), Clinical Information System(CIS) and Patient Data Management Information System(PDMS). Information Systems are also being used across the banking sector, for example Data Mining and Data Warehousing. Riskompass has also being implemented across the banking sector in order to calculate risk and the Electronic Clearing Service which facilitates paperless transactions.( For more information regarding I.S in the Banking Sector see this interesting article http://www.scribd.com/doc/22553515/Management-Information-System-MIS-in-Banking-Sector
There is also an Geographic Information System(GIS) which is used to interpret data, trends etc and it offers huge benefits to the industry such as cost saving, increased efficiency and better record keeping. For more on its use in geography see the following link http://www.esri.com/what-is-gis. Information systems are also used in the steel industry, power industry and others. I believe the future of information systems will be in its use across all sectors, industries and organisations that will improve operations on a day to day basis and decision making.
