Management
|
is a process by which organizational goals are achieved through the use of resource (people, money, energy, materials, space, time).
These resources are considered to be inputs; The attainment of the goals is viewed as the output of the process; The ratio between inputs and outputs is an indication of the organization’s productivity |
|

|
monitor, disseminator, spokesperson
|
|
Decisional roles
|
entrepreneur, disturbance handler, resource allocator, negotiator
|
|
Decision
|
refers to a choice that individuals and group make among two or more alternatives.
|
|
Decision making
|
is a systematic process composed of three major phases: intelligence, design and choice (Simon 1977)
Implemetation phase was added later. |

Decision support systems (DSSs)
|
provide support primarily to analytical, quantitative types of decisions.
|
|
Executive support systems (ESSs)
|
support the informational roles of executives.
|
|
Group decision support systems (GDSSs)
|
supports managers and staff working in groups.
|
|
Structured
|
routine and repetitive problems for which standard solutions exist.
|
|
Unstructured
|
“fuzzy”, complex problems for which there are no cut-and-dried solutions
|
|
nature of decisions
operational control |
executing specific tasks efficiently and effectively;
|
|
management control
|
acquiring and using resources efficiently in accomplishing organizational goals;
|
|
strategic planning
|
the long range goals and policies for growth and resource allocation.
|
|
Decision support systems (DSSs)
|
are computer-based information systems that combine models and data in an attempt to solve semistructured and some unstructured problems with extensive user involvement.
|
|
Sensitivity analysis
|
is the study of the impact that changes in one (or more) parts of a model have on other parts.
|
|
What-if analysis
|
is the study of the impact of a change in the assumptions (input data) on the proposed solution.
|
|
Goal-seeking analysis
|
is the study that attempts to find the value of the inputs necessary to achieve a desired level of output.
|
|
Data management subsystem
|
contain all the data that flow from several sources.
|
|
Model management subsystem
|
contains completed models and the building blocks necessary to develop DSS applications.
|
|
User interface
|
covers all aspects of the communications between a user and the DSS
|
|
Users
|
are the persons faced with the problem or decision that the DSS is designed to support.
|
|
Knowledge-based subsystems
|
provide the required expertise for solving some aspects of the problem.
|
|
Virtual group
|
is a group whose members are in different locations.
|
|
Group decision support system (GDSS
|
is an interactive computer-based system that supports the process of finding solutions by a group of decision makers.
|
|
Decision room
|
is a face-to-face setting for a group DSS, in which terminals are available to the participants.
|
|
Organizational Decision Support System (ODSS)
|
is a DSS that focuses on an organizational task or activity involving a sequence of operations and decision makers and provides the following:
It affects several organizational units or corporate problems; It cuts across organizational functions or hierarchical layers; It involves computer-based and (usually) communications technologies. |
|
Executive information system (EIS)
|
is a computer-based technology designed specifically for the information needs of top executives and provides for:
Rapid access to timely information; Direct access to management reports; Very user friendly and supported by graphics. |
|
Exception reporting
|
reporting of only the results that deviate from a set of standards.
|
|
Drill down reporting
|
investigating information in increasing detail.
Easily connected within online information services and e-mail. Include analysis support, communications, office automation and intelligence support. |
|
Intelligent systems
|
is a term that describes the various commercial applications of AI.
|
|
Artificial intelligence
|
is a subfield of computer science concerned with:
studying the thought processes of humans; recreating those processes via machines, such as computers and robots. “Behavior by a machine that, if performed by a human being, would be considered intelligent.” |
|
Turing test
|
is a test for artificial intelligence, in which a human interviewer, conversing with both an unseen human being and an unseen computer, cannot determine which is which; named for British AI pioneer Alan Turing.
|
|
Expertise
|
refers to the extensive, task-specific knowledge acquired from training, reading and experience.
|
|
Expert systems (ESs)
|
attempt to mimic human experts by applying expertise in a specific domain.
Can support decision makers or completely replace them. |
|
Knowledge acquisition
|
Knowledge is from experts or from documented sources
|
|
Knowledge representation
|
Acquired knowledge is organized as rules or frames (objective-oriented) and stored electronically in a knowledge base.
|
|
Knowledge inferencing
|
Given the necessary expertise stored in the knowledge base, the computer is programmed so that it can make inferences. The reasoning function is performed in a component called the inference engine, which is the brain of ES.
|
|
Knowledge transfer
|
The inferenced expertise is transferred to the user in the form of a recommendation.
|
|
Knowledge base
|
contains knowledge necessary for understanding, formulating and solving problems.
|
|
Inference engine
|
is a computer program that provides a methodology for reasoning and formulating conclusions
|
|
User interface
|
enables users to communicate with the computer
|
|
Blackboard
|
is an area of working memory set aside for the description of a current problem.
|
|
Explanation subsystem
|
explains its recommendations
|
|
Natural language processing (NLP):
|
Communicating with a computer in English or whatever language you may speak
|
|
Natural language understanding/speech (voice) recognition
|
The ability of a computer to comprehend instructions given in ordinary language, via the keyboard or by voice.
|
|
Natural language generation/voice synthesis
|
Technology that enables computers to produce ordinary language, by “voice” or on the screen, so that people can understand computers more easily.
|
|
Neural networks
|
is a system of programs and data structures that approximates the operation of the human brain
|
|
