6. • What is IS? Simply, Information System is an organized
system for collection, organization, storage and
communication of information.
• Specifically, IS is concerned with the study of
complementary networks that people and organization
use to collect, filter, process, create and distribute data
• ‘Why we need IS?’ This question has evolved into a
moot issue. As marketing, accounting, finance, human
resource management, operation management,
information system has become an integral part of
many business organizations.
• In today’s world of technology, many call it business
imperative.

24. Foundation Concepts
The components of Information Systems

25. System
• A set of interrelated components, with a clearly defined
boundary, working together to achieve a common set of
objectives by accepting inputs and producing outputs through
a transformation process in an organized manner
• 3 basic functions of a system
– Input involves capturing and assembling elements that enter
the system (to be processed).
– Processing involves transformation method (that convert input
elements to output).
– Output involves transferring elements that have been produced
by transformation process to ultimate destination.
• Feedback is data about the performance of a system.
• Control involves monitoring and evaluating feedback, and
making necessary adjustment to inputs & process

26. Components of Information System
• Information Systems use people, hardware, software, data and network
resources to perform input, processing, output, storage and control
activities that transform data into information products.

27. Information System Resources
1. People are the essential ingredient for the successful
operation of all information system. It includes end
users and IS specialist.
 END USERS are people who use an information system or
the information it produces. They can be customers , sales
person, clerks, engineers, accountants, managers who are
found at all levels.
 Knowledge workers who collaborate & communicate
 IS SPECIALIST are people who develop and operate
information system. It includes system analysts, software
developers, system operators, technical & clerical IS persons

28. Information System Resources
2. Hardware Resources includes all physical devices and
material used in information processing. It includes not
only machines, such as computers but also all data
media, i.e. tangible objects on which data is recorded.
 COMPUTER SYSTEM : consist of central processing units
containing micro processors and a variety of
interconnected devices such as printers , scanners etc.
 COMPUTER PERIPHERALS: are devices such as keyboard,
electronic mouse for the input of data and commands , a
video screen or printers for the output of the
information, magnetic or optical drives for storage of
data resources

29. Information System Resources
3. Software resources includes all sets of information
processing instructions.
It includes the sets of information processing instruction
called programs which direct and control computer hardware
and the set of operating instructions called procedure that
people need.
 Example:
• System software: OS which control and supports the
operation of computer system
• Application software: sales analysis, payroll, word processing
programs
• Procedures: Operating instructions for the people who use IS
– Data entry, error correction, paycheck distribution procedures

30. Information System Resources
4. Data resources are the input elements that are stored in
databases. This concept has been broadened by managers
and information system professionals. They realize that data
constitute valuable organizational resources.
 Data can take many forms: alphanumeric, text, images,
video, audio
 Data can take many forms including traditional numeric data
composed of numbers etc. The data resources of information
system are typically organized, stored, accessed by a variety
of data resource management technologies into:
 Data base that hold processed and organize data.
 Knowledge bases that hold knowledge in a variety of forms
such as facts, rules and cases of best business practices

31. Information System Resources
5. Network resources includes communications technologies
and networks that are fundamental to all information
system. It includes:
 Communication Media- includes twisted pair wire,
microwave, cellular wireless technologies.
 Network Infrastructure- emphasizes that many hardware,
software and data technologies are needed to support the
operations and use of communication network.
– Communication processors such as modems,
communication control software, network OS, internet
browser packages.

40. MANAGERIAL CHALLENGES
• IS and technologies must be managed to support business
strategies, business processes and organizational structures
and culture of a business enterprise
• Success and failure of IT should not be measured only by
efficiency in terms of minimizing cost, time and the use of
information resources.
• It should also be measured by effectiveness in supporting
business strategy, enabling business processes, enhancing
organizational structure and culture and increasing the
business and customer values
• However, IS & technology could be mismanaged and
misapplied resulting into not only technical problem but
also a business failure.
• Ex. Dell - Corporate Support call center

41. MANAGERIAL CHALLENGES
• Developing IS Solutions
– Agile : system is defined at high level and then developed
in short iterations
– Usable software after each iteration
• Challenges and Ethics of IT
– What might be considered improper, irresponsible and
harmful to other people or society
– Proper business use of IT, internet and organization’s IT
resources
– How to protect yourself from computer crime and other IT
risks
– Ex. CRM and HRM cases
– Ex. Hannaford Bros – Importance of securing cust. Data

42. MANAGERIAL CHALLENGES
• Challenges of IT career
