People Technology
People are the 5th component of an Information System
Everyone forgets the importance of people in an information system.
Example: End User, Data Entry Person, Manager, Programmer, DB Administrator, Cashier, Secretary, Professor.

Information Systems Serve 3 Roles
IS can support 3 different levels in business
![Page 8: What is an Information System](https://reader035.vdocuments.net/reader035/viewer/2022081514/568134aa550346895d9bb975/html5/thumbnails/8.jpg)
Expanding Role of IS
Information Systems are being used in more areas, especial at the strategic level.
At the same time, Information Systems are expanding participation of End Users (The Grunts)
Biggest advantages of IS: Information can flow up the pyramid faster and more effectively.

Types of Information Systems
![Page 10: What is an Information System](https://reader035.vdocuments.net/reader035/viewer/2022081514/568134aa550346895d9bb975/html5/thumbnails/10.jpg)
Transaction Processing System (TPS)
Supports Operations Updates Operational Databases Examples:
ATM Machine System – Banking Transactions Cash Register System – Point of Sale Transactions Accounting System – Checking Account Transactions Even Pay-per-view or OnDemand is a TPS
![Page 11: What is an Information System](https://reader035.vdocuments.net/reader035/viewer/2022081514/568134aa550346895d9bb975/html5/thumbnails/11.jpg)
Process Control Systems (PCS)
Supports Operations Monitor and Control
Industrial/Manufacturing Process Examples:
Petroleum Refining Power Generation Automobile Manufacturing

Enterprise Collaboration Systems (ECS)
Supports Operations (Surprised?) Teamwork, communication, and collaboration Examples:
E-mail Chat Video Conferencing Calendaring Journaling Workflow File Sharing (Kazaa, Morpheus, Limework, Napster)
![Page 13: What is an Information System](https://reader035.vdocuments.net/reader035/viewer/2022081514/568134aa550346895d9bb975/html5/thumbnails/13.jpg)
Management Information System (MIS)
Supports Management (duh?) Analysis & Reporting Charts, Graphs, Summary Tools Examples:
SCT Banner – Managing College Information (Siena uses it)
Spreadsheet (Excel) – One of the first and most basic Oracle's Corporate Performance Management

Decision Support System (DSS)
Support Management What-if Analysis, Decision Modeling, Scenario
Building, Highly interactive, ad hoc. Examples
Enterprise Decision Manager 2.0 Fair Isaac Corporation
AIMMS 3.6 Most DSS’s are custom developed for specific
companies; very few out-of-the-box products.

Executive Information Systems (EIS)
Supports high-level strategic management Provides critical info from other systems (MIS and DSS). Portal Concept: one place will links to all information EIS’s integrate external information such as economic
developments and news about related markets and competitors. Helps strategic decision making, not necessarily tactical. Tactical – doing things the right way right Strategic – doing the right things
