, Week 1: Introduction to IS (Ch. 1)
An Information System (IS) is the study of complementary networks of hardware and software that people and
organizations use to collect filter, process, create, and distribute data.
Piccoli’s components of an IS:
Social System vs Technical System.
Components: Structure (Social), Technology (Technical), People (Social), Process (Technical)
• Automation: Technology and Process (speed up, reduce costs, reduce error)
• Information: Technology, Process and People (interpret data, better informed)
• Transformation: Technology, Process, People and Structure (change structure of
org.)
Question 1: When structure is part of the IS. How does IS relate to organization?
According to Mark S. Silver it can be categorized between two viewpoints:
IS-Centered View of an Information System
• Hardware, Software, Data, People and Procedure
Managerial View of an Information System
• Business Process, People, Information Systems
Information System is a socio-technological system, it is covers one of the aspects that
covers a wide range of components.
Question 2: Where is the information?
One approach: Language/Action Perspective (LAP)
It focuses the IS that people are communicating with each other.
What is communicating? Communication is more than just data/information flow! A
computer as a data processing system, it cannot act like people do when they communicate.
• Focuses on what people do when communicating (how to do things with words)
