Characteristics of Valuable Information
Accurate information is error free. Complete information contains all of the important
facts. Relevant information is important to the decision
maker. Timely information is available when needed. Verifiable information can be checked to make sure it
is correct. Accessible information can be obtained by the users
who need it. Secure information is safe from unauthorized users.

Usefulness of information depends on quality and accessibility
BUT…. Usefulness also depends on purpose and context Information comes in different forms - not all of
which can be quantified: hard vs. soft data Ownership is difficult to maintain More is not always better

Definitions
The business environment includes the firm itself and everything else that affects its success, such as competitors; suppliers; customers; regulatory agencies; and demographic, social, and economic conditions.
A firm (or government organization) consists of a large number of interdependent business processes that work together to generate products or services in a business environment.
A business process is a related group of steps or activities that use people, information, and other resources to create value for internal or external customers of a firm.

What is an Information System?
An information system is the set of interrelated components that collect, process, store and distribute information used by/support one or more business process.
Input: The collection of raw data. Processing: The manipulation of data into information. Output: Distributing valuable information.
Includes both technology and people
Information technology is the hardware, telecommunications and software that make information systems possible.

Definitions Input The capture or collection of raw data
from within the organization or from its external environment for processing in an information system,
Processing The conversion, manipulation, and analysis of raw input into a form that is more meaningful to humans.
Output The distribution of processed information to the people who will use it or to the activities for which it will be used.
15
Definitions Feedback Output that is returned to the
appropriate members of the organization to help them evaluate or correct input.
Computer-based information systems (CBIS) Information systems that rely on computer hardware and software for processing and disseminating information.
Formal system System resting on accepted and fixed definitions of data and procedures, operating with predefined rules.
16
Examples of Information Systems
17
Definitions: Organization Standard operating procedures (SOPs) Formal
rules for accomplishing tasks that have been developed to cope with expected situations.
Knowledge workers People such as engineers or architects who design products or services and create knowledge for the organization.
Data workers People such as secretaries or bookkeepers who process the organization's paperwork.
Production or service workers People who actually produce the products or services of the organization.
18
Definitions: Management Senior managers People occupying the
topmost hierarchy in an organization who are responsible for making long-range decisions.
Middle managers People in the middle of the organizational hierarchy who are responsible for carrying out the plans and goals of senior management.
Operational Managers People who monitor day to day activities of the organization.

Assumes that people behave rationally and focuses on creating systems with the best technical capabilities
Main emphasis is on the political , organizational, and human elements that impact information systems. What seems rational and technically correct may not work due to behavioral elements in the organization.

Brief History of IS 1950's : Electronic Data Processing/
Automatic Data Processing 1960's : Management Information Systems
(i.e. Report generating systems) 1970's : Decision Support Systems (DSS),
Office Automation Systems 1980's : Information as strategic tool, End-
User Computing, Managerial control 1990's : Integration: Core activities +
Information as a product
22
The New Role of Information Systems in Organizations Widening scope of information systemsData processing -> management control -> decision support->
information as a resource Network revolution Networked enterprise
Flattening organizations Separating work from location Reorganizing workflow Increasing flexibility of organization Mass customization: Products can be easily customized with no
added cost for small production runs. Changing management process – ERP Inter-organizational systems: Information system that
automate work flow of information across organizational boundaries
