CHAPTER 8
What are the three levels
of management activity?
Operational
Tactical
Strategic
Operational management
level?
Composed of supervisory managers that
develop short-range plans such as
weekly production schedules.
Tactical management
level?
Composed of middle managers that
develop short- and medium-range plans
Strategic management
level?
Composed of a board of directors and an
executive committee of the CEO who
develop overall organizational goals,
strategies, policies as a part of a strategic
planning process.
What is a Structured
decision?
Repetitive and routine problems for which
standard solution exist.
The procedures to follow can be
specified in advance.
What is a Semi-structured
decision?
Some decision procedures can be prespecified, but not enough to lead to a
definite recommended decision.
What is an Unstructured
Decision?
The procedures cannot be specified in
advance.
Unstructured problems are novel and
non-routine, complex.
Ex: new business planning
Decisions made at the
operational management
level tend to be more
Structured
Decisions made at the
tactical management level
tend to be more
Semi-structured
Decisions made at the
strategic management level
tend to be more
Unstructured
What are the management
support systems?
Management Information systems
Decision support systems
Executive information systems
What is an exception
report?
Exception reports, highlighting only
exceptional conditions, such as when a
customer exceeds their credit limit, a
manager would probably get an
exception report.
What are the characteristics
of the Decision Support
Systems?
Interactive
Supports semi-structured and unstructured
decisions
What is a What-if
analysis?
What-if analysis attempts to check the
impact of a change in the assumptions
on the proposed solution.
What if we cut advertising by 10 percent?
What is a Sensitivity
Analysis?
When the value of one variable is
changed repeatedly and the resulting
changes in other variables are observed.
What is a goal-seeking
model?
Attempts to find the value of the inputs
necessary to achieve a desired level of
outputs.
What is Data
Visualization?
Data visualization refers to presentation
of data in graphical form instead of
traditional form of text and table.
What is Geographical
Information System (GIS)?
A GIS is a data visualization technology
that captures, stores, checks, integrates,
manipulates, and displays data using
digitized maps.
What are the characteristics
of Executive Information
Systems (EIS)?
Provide management with immediate and
easy access to information about the firm’s
critical success factors.
Are most useful to managers at the
strategic level of management.
Support unstructured decision-making
process.
What is drill down?
provides details behind any given
information.
What is Data mining?
organizing valuable business information
in a large database
What is Artificial
Intelligence?
AI is the effort to develop computer
based systems that behave as humans.
What are the major areas
of AI?
Cognitive science
Robotics
Natural interfaces
What are the major areas
of Cognitive science?
intelligent agents,
neural networks,
fuzzy logic.
What is an Intelligent
agent?
It is a software surrogate for end user or
process that fulfills a stated need or
activity.
Systems that use massively
parallel processors whose
architecture is based on the
human brain’s neuron
structure are called
Artificial Neural Networks
What is a Fuzzy Logic
system?
system that can process ambiguous data
and quickly provides approximate, but
acceptable solutions to problems.
What are the
characteristics of an
Expert system?
They are designed to replicate and then
to replace a human advisor.
They transfer expertise from an expert
and documented sources to a computer
and then to the user.
CHAPTER 9
What are the major
components involved in IT
Planning process?
Strategy development
Resource management
Technology architecture
What are the ways for
minimizing end-user
resistance?
Proper end user training
Improved communications with IS
personnel
End user involvement in the development
and implementation of new systems
What is the major focus of
organizational change
management?
People
CHAPTER 10
What are the steps in the
SDLC?
systems analysis,
systems design,
programming,
testing,
implementation (conversion),
and production & maintenance.
What is the function of
systems analysis stage?
ANALYSIS OF PROBLEM TO BE
SOLVED
What is feasibility study?
Determining whether the proposed
system is feasible financially,
economically, technically, and
operationally.
What is SYSTEMS
DESIGN?
describes how the system will accomplish the task.
What are the major forms
of CONVERSION?
Parallel
Phased
Direct
Pilot
What is parallel
conversion?
The conversion process in which both the
old and new system are operated for a
time.
What are the alternative
system-building approaches?
Prototyping
Application software packages
End-user development
Outsourcing
What is Prototyping?
Using prototype which is a working
version of an information system or part
of the system for discovering how a
system should operate.
What is outsourcing?
Purchase of product or service from another
company.
