Type of Information SystemsInformation systems corresponding to each one of those levels(Laudon & Laudon, 2007): Executive information Systems(EIS) Management InformationSystems (MIS) /Decision Support Systems(DSS) Transaction ProcessingSystems (TS)
Types of Information Systems Three Types of Work-Changing IT (McAfee, 2006): Function IT (FIT), facilitates standalone tasks. facilitate the work of a single person (or task, job, function, or role) Network IT (NIT), facilitate interactions among multiple people (or tasks, jobs, etc.) enables unstructured interactions. Enterprise IT (EIT) , facilitate interactions among multiple people (or tasks, jobs, etc.) imposes structured interactions. There are also a few hybrid technologies
Types of Information Systems Function IT (FIT), facilitates standalone tasks. Spreadsheets and word processors - perhaps the most common FITs; they help analysts and writers, respectively, with their work. Function technologies also exist for specialists such as: − design engineers, − statisticians, − architects, − photographers, and − poker players. − ...
Types of Information Systems Network IT (NIT), enables unstructured interactions. Network technologies let people and groups come together, share information, and collaborate without specifying the terms of the collaboration. Network technologies fall into two groups: − channels and − platforms. Channels like email, IM, and SMS allow one party to send information to another privately. Outside of the sender(s) and receiver(s), no one can see the information transmitted over channels, or even know that a transmission took place. Platforms, on the other hand, make information visible and permanent.
Types of Information Systems Enterprise IT (EIT) , imposes structured interactions. There have been lots of attempts to ‘carve up’ the EIT space into ERP, SCM, CRM, eProcurement, etc. but these applications really have the same goal, just with different organizational footprints. Structure can be imposed at two different levels: − Data - EDI and XML are EITs at the data-only level; − Process parameters - ERP, SCM, and CRM impose structure on both data and business processes.
Types of Information Systems There are also a few hybrid technologies: Knowledge Management systems impose structure on data, but not on how people use the data. Groupware, on the other hand, establishes processes for sharing information, but does not pre-define what kind of information can be shared. Andrew McAfee coined the concept of Enterprise 2.0 (McAfee, 2009): Enterprise 2.0 is the use of emergent social software platforms within companies, or between companies and their partners or customers.

IOSInter-organizational Information SystemsAn information system that supports information flow among two or more organizations. IOS have developed in direct response to two business pressures (drivers): – the desire to reduce costs and to improve the effectiveness and – timeliness of business processes.
IOSTypes of Interorganizational Systems. B2B trading systems Global systems Electronic funds transfer (EFT) Groupware Integrated messaging Shared databases Systems that support virtual corporations.
IOSIOS classification based on the technology Electronic data interchange (EDI) Extranets XML Web services
