6The MIS Concept
- The MIS concept addresses the use of IT to
improve individual and organizational performance
at two levels - producing better tangible outputs
- developing tools and processes that allow better
management decision making
7Level 1 Better Tangible Outputs
- IT is used to make the process in producing a
tangible output more efficient and more effective - Implication Issues
- whether or not to use IT
- selecting the proper IT
- employing correct procedures for the utilization
of the IT
8Level 2 Intangible Outputs
- A schematic view - the information/decision level
- MIS involves identifying the key decisions that
are related to reaching objectives, on
determining the proper information needed to make
these decisions, and on improving the decision
processes employed to make the decisions. - Implications Activity at this level concentrates
on developing tools and processes that allow
better management decision making
9The MIS Concept - Level 2Intangible Outputs
(achieving desired objectives)
10Data versus Information
11Information Concepts
The body of guidelines and procedures used to
select, organize, and manipulate data to make it
suitable for a specific task.
A collection of facts organized in such a way
that they have additional value beyond the value
of facts themselves.
Raw facts
12Information Concepts
Knowledge Base The collection of rules,
procedures, and relationships that must be
followed to achieve informational value or proper
process outcome.
ProcessA set of logically related tasks
performed to achieve a defined outcome.
13Types of Data
- Data represented by
- Alphanumeric Data Numbers, letters, and other
characters - Image Data Graphic images or pictures
- Audio Data Sound, noise or tones
- Video Data Moving images or pictures
14The Value of Information(Figure 1.2)
15Characteristics of Valuable Information
- Accurate information is error free
- Complete information contains all of the
important facts - Flexible information can be used for a variety of
purposes - Reliable information can be depended on
- Relevant information is important to the decision
maker - Timely information is delivered when it is needed
- Verifiable
- Accessible
16Attributes of Information Quality
17System Concepts
- What is a system?
- A set of components that interact to accomplish
goals - Systems can be viewed as process models in terms
of their inputs, outputs, processing, and
feedback/control mechanisms. Examples. - What is an IS?
- A set of interrelated components that collect
input, process, and output data and information
and provide a feedback/control mechanism - What is a CBIS?
- An IS that uses IT.
- Components hardware, software, databases,
networks, people, procedures
18System Examples
- University an example
- Inputs students, faculty, textbooks
- Processing mechanisms teaching, research,
service - Output graduates
- Goal acquisition of knowledge
- The Manufacturing System
- - another example
- Other Examples
- Subsystem, interface,
- open, adaptive

20Systems Some Examples
- University
- Inputs Students, Faculty, Textbooks
- Processes Education/Courses
- Output graduates
- Feedback surveys, grades
- Toyota Plant
- Inputs raw materials, components
- Processes assembly line
- Output mini-vans
- Feedback customer surveys, quality reports
- Fast Food IS
- Inputs consumer orders
- Processes processing software
- Output receipts, cooks order list
- Feedback invalid entry message
- Video Store IS
- Inputs rentals, returns
- Processes processing software
- Output reports, rental agreement
- Feedback error repots
21System Classifications and Characteristics
Subsystem System Boundary Interface Open,
Adaptive Systems
22Input, Processing, Output, Feedback/Control
Output that is used to make changes to input or
processing activities
23Components of an Information System
24Procedures
- Procedures - set of instructions used by people
to complete a task - Procedures include the strategies, policies,
methods, and rules for using the CBIS. - Examples procedures describe
- When each program is to be run
- Who can have access to database
- What is to be done in case of a disaster
25System Performance StandardsEfficiency and
Effectiveness
- Efficiency a measure of what is produced
divided by what is consumed - an improved product
- the same level product produced cheaper or faster
- the improvement in the product exceeds the
increased cost
- Effectiveness a measure of the extent to which
a system achieves its goals. - Goal to reduce damaged parts by 100 units
- Q Actual reduction in damaged parts using a
control system is only 85 units. Effectiveness? - A The effectiveness of the control system is 85
percent
26An IS Framework for Business Professionals
27What You Need to Know
- Foundation Concepts Fundamental concepts about
the components and roles of IS - IT Major concepts, developments, and management
issues in information technologies - Business Applications The major uses of IS for
the operations, management, and competitive
advantage - Development Processes How end users or
information specialists develop and implement IS - The challenges of effectively and ethically
managing information technologies, strategies,
and security at the end user, enterprise, and
global levels of a business
28Major Roles of Information Systems
29History of the Role of IS
30Trends in ISs
- Data Processing 1950s -
- Transaction processing, record keeping,
traditional accounting applications - Management Reporting 1960s -
- MIS predefined management reports for
decision-making purposes - Decision Support 1970s -
- DSS interactive ad hoc support of the
managerial decision-making process - Strategic and End User Support 1980s -
- EUC, Executive Information Systems, Expert
Systems, Strategic Information Systems - Electronic Business and E-Commerce 1990s -
31The Electronic Business
32Ethical Dimensions of IT
- What uses of IT might be considered improper,
irresponsible, or harmful to other individuals or
to society? - What is the proper use of an organizations
information resources? - What does it take to be a responsible end user of
IT? - How can you protect yourself from computer crime
and other risks of IT?
