Concludes the Answer is Yes - Worlds best performing companies spent 7 more
per employee on IT than typical companies - They recouped the investment fivefold in lower
operational costs - Todays business professionals must know how to
develop and use IT
5The Power of Digital Systems
- Binary counting system uses only two digits
0 and 1 - Digital systems
- Computers and devices that use the binary system
- Can represent any information as a combination of
zeros and ones - Information can be represented, stored,
communicated, and processed digitally
6The Power of Digital Systems (continued)
- Digital information is stored and communicated by
means of electromagnetic signals - Extremely fast
- Digital copy is an exact copy of the original
- Accuracy and speed make digital systems powerful,
useful, and important
7The Purpose of Information Systems
- Businesses use information systems
- To make sound decisions
- To solve problems
- Problem any undesirable situation
- Decision arises when more than one solution to
problem exists - Both problem solving and decision making require
information
8The Purpose of Information Systems (continued)
- Keys to success in business
- Gathering correct information efficiently
- Storing information
- Using information
- Purpose of information systems is to support
these activities
9Data, Information, and Information Systems
- Data, information, and system are commonly
used terms - Important to understand their similarities and
differences
10Data vs. Information
- Data a given or fact
- Can be number, statement, or picture
- Is the raw material in the production of
information - Information facts or conclusions that have
meaning within context - Composed of data that has been manipulated
11Data Manipulation
- Data is manipulated to make useful information
- New information can be generated from data, such
as averages, trends, etc. - Survey is common method of collecting data
- Raw data is hard to read
- Information is more useful to business than data
12Generating Information
- Process the manipulation of data
- Usually produces information
- May produce more data
- A piece of information (output of a process) in
one context may be considered data (input to a
process) in another context
13Generating Information (continued)
14Information in Context
- Not all information is useful
- To be useful, information must be
- Relevant
- Complete
- Accurate
- In business, information must also be
- Current
- Obtained in a cost-effective manner
15Information in Context (continued)
16Exercise No. 1
- Give your own example on the difference between
data vs information. Take an example from the
different businesses here in Pohnpei like banks,
retail/wholesale stores, gas stations etc. You
could also use as an example our very own
departments/groupings here in the college like
the library, Business Office, Financial Aid etc.
(10 pts) - Give your own examples of at least two of the
characteristics that makes up a useful
information that is not on the textbook (see Page
11). (10 points)
17What Is a System?
- System array of components that work together to
achieve goal or goals - System
- Accepts input
- Processes input
- Produces output
18What is a System? (continued)
- System may have multiple goals
- System may contain subsystems
- Subsystem component of a larger system
- Subsystems have subgoals that contribute to main
goal - Subsystems can receive input from and transfer
output to other subsystems
19What is a System? (continued)
20What is a System? (continued)
- Closed system has no connections with other
systems - Open system interfaces and interacts with other
systems - Often a subsystem of a bigger system
- Subsystems by definition are always open
- Information system (IS) components that work
together to process data and produce information
21Information and Managers
- Systems thinking thinking of an organization in
terms of subsystems - Powerful management approach that creates a
framework for problem solving and decision making - Helps keep managers focused on overall goals

information among subsystems
22Information and Managers (continued)
- Information map description of data and
information flow within an organization - Shows a network of information subsystems that
exchange information with each other and with the
outside world - Information technology technologies that
facilitate construction and maintenance of
information systems
23The Benefits of Human-Computer Synergy
- Humans are relatively slow and make mistakes
- Computers cannot make decisions unless programmed
to do so - Synergy combining resources to produce output
that exceeds the sum of outputs of the separate
resources by themselves - Human-computer combination allows human thought
to be translated into efficient processing of data
24The Benefits of Human-Computer Synergy
(continued)
25Information Systems in Organizations
- Information system consists of data, hardware,
software, telecommunications, people, and
procedures - Computer-based Information system system with
one or more computers at center - Organizations lag behind and lose competitiveness
if they do not use information systems
