Information Systems Midterm Review
Synopsis: In order to achieve an objective, you must use an Information System, which is
composed of Information Technologies (such as Data, Hardware, and Software)
Information Systems
-Information Technology (IT)
-hardware, software, etc. used to store and organized data
-Examples of IT (Types of Components that make up an IS)
1) Data 4) Media
2) Hardware 5) Procedures
3) Software 6) People
-Information Systems (IS)
-combo of hardware, software, etc. people use to accomplish a specific objective
Three Pillars of Information Tech Growth
You need pillars to make a DEC(k)
1) Digital
-if a good is digitalized, it can be replaced perfectly and distributed with
low costs and is easily measured
2) Exponential
-Information technology has been exponentially improving (the rate of
growth) in the past decades
3) Combinational
-Information technology can be combined by layering with other tech
advances
-Business Process
-Business Process
-collection of related activities that produce a specific product
-combination of different departments working together through a series
-Algorithm
-sequence of steps that solve a distinct problem
-sometimes just one activity or task
-Flowchart
-Diagram that provides visual view of an algorithm or business process
-Role of Information Systems in Organizational Change
-Process Improvement
-Business Process Improvement (BPI)
-Process=structured set of activities designed to produce an output
-Automation
-Business Process Automation (BPA)
-Redesign
-Business Process Re-engineering (BPR)
-Reengineering=fundamental rethinking and radical redesign of business
processes
-Process Control
-enforces business rules, ensures that processes are followed

-Information Flow
-improves communication and efficiency
-Types of Information Systems
-Different situations/objectives require certain types of information system
