Slide 2

Objective Identify data handling as the establishment of administrative work Identify which media are more appropriate for supporting administrative work Describe basic leadership/critical thinking frameworks in Organizations Decision bolster substance of various sorts of data frameworks

Slide 3

Objective Differences in qualities of Information Systems Discuss models of basic leadership Describe basic leadership prepare Describe Decision Support Systems (DSS) Describe real subjects Describe advantages of DSS

Slide 4

Objectives Examine DSS association with: choice errand structure choice setting client mental sorts

Slide 5

Objectives Describe seven essential sorts of DSS Discuss diverse classes of DSS Based on bolster Data-Based DSS Model-Based DSS Expert System Based on nature of choice circumstance Based on number of clients Examine how DSS viability is decreased

Slide 6

How can data frameworks help administrative function? What do chiefs do? Capacities: Plan, compose, summon, organize, control. Parts interpersonal enlightening decisional

Slide 7

How can data frameworks help administrative function? Data preparing establishments of Managerial work Information taking care of, basic leadership, correspondence The motivation behind Information preparing decreasing instability and settling obscurity Media appropriate for dealing with vulnerability and dubiousness - Richness

Slide 8

Which media is more reasonable to bolster administrative work? Media Richness Rules & directions uncommon reports MIS Direct contact Group gatherings DSS Equivocality diminishment (illuminate, achieve assentions choose which things to ask) Uncertainty lessening (acquire extra information look for answers to unequivocal inquiries) Less Rich More Rich

Differences in System Characteristics

Slide 14

Models of Decision Making Rational model Economic reasonable on-screen character - gets every one of the actualities, measures probability of all the option results, and picks the one with the most elevated likely value.(expected esteem) Expected money related esteem $100M A $10M $200M B - $20M * Bounded judiciousness

Slide 15

Models of Decision Making Satisficing Less than enhancement More practical Limited number of options Organizational and Political Sub-units or individuals with possess "objectives" and "assets" Power battle Bargaining and arrangement

Slide 16

Decision Making Process Decision making process Intelligence Sensing, discovering, recognizing, and characterizing issue/opportunity Design Diagnosing the issue/opportunity Generating options Choice Choosing the best option

Slide 17

Decision Support Systems a data framework reason to give data to settling on educated choices intuitive (required for testing and prospecting)

Slide 18

Definitions of DSS Gorry and Scott-Morton (1971): Management Decision Systems - Interactive PC based frameworks, which help chiefs use information and models to tackle unstructured issues. Sharp and Scott-Morton (1978): Decision emotionally supportive networks couple the scholarly assets of people with the capacities of the PC to enhance the nature of choices. It is a PC based emotionally supportive network for administration chiefs who manage semi-organized issues.

Slide 19

Basic Themes of DSS Information frameworks. Utilized by directors. Utilized as a part of deciding. Used to bolster, not to supplant individuals. Utilized when the choice is "semistructured" or "unstructured." Incorporate a database or the like. Fuse models.

Slide 20

DSS Benefits Improving Personal Efficiency Expediting Problem Solving Fascilitating Interpersonal Communications Promoting Learning or Training Increasing Organizational Control

Slide 21

DSS as a System Man-Machine System DSS is man-machine framework for basic leadership purposes. Man part is more open and probabilistic while the machine part is more shut and deterministic. E.g. DSS for choosing PRICE and ADVERTISING levels Closed-circle framework with criticism outer to framework DSS utilizes input to modify yield. Input is not inward like a lift. The client gives judgmental contributions to DSS. DSS parts: Database, demonstrate base, learning base, interface which communicate with each other and the client.

Slide 23

DSS: Decision Task, Context, User DSS association with Task Nature of choice errand characterization by structure Structured Unstructured

Slide 24

DSS: Decision Task, Context, User DSS association with Decision Context Decision Context Emergent versus built up setting Level of basic leadership - Scope Strategic Managerial Operational

Slide 25

Information Characteristics for Different Types of Decisions

Slide 26

DSS: Decision Task, Context, User's Psychological Types To take a trial of your identity, go to http://www.davideck.com (discretionary) Introversion versus Extraversion less versus more quick association on line visit versus deferred electronic exchange Sensing versus Instinct expansive number of certainties versus less information more 'hunches " information arranged DSS versus less comprehensive DSS

Slide 27

DSS: Decision Task, Context, User's Psychological Types contd. Thinking versus Feeling more utilization of rationale versus more human/diverse Optimization or proposal models versus "amass product" Judgment versus Discernment fast to choose versus ease back to choose demonstrate situated DSS versus information situated DSS

Slide 28

DSS: Decision Task, Context, User DSS relationshio with User

Slide 29

Taxonomy of DSS Basis for scientific classification: how much the framework decides the choice

Slide 30

The DSS Hierarchy Suggestion frameworks Optimization frameworks Representational models Accounting models Analysis data frameworks Data examination frameworks File drawer frameworks

Slide 31

File Drawer Systems They are the least complex kind of DSS Can give access to information things information is utilized to settle on a choice ATM Machine Use the adjust to settle on exchange of assets choices

Slide 32

Data Analysis Systems Provide access to information Allows information control abilities Airline Reservation framework No more seats accessible give elective flights you can utilize the information to make flight arrangements

Slide 33

Analysis Information Systems Provide access to numerous information sources Combines information from various sources Allows information investigation capacities Compare development in incomes to industry normal obliges access to many sources The normal for the current "datawarehouse" is comparative

Slide 34

Accounting Models Use interior bookkeeping information Provide bookkeeping displaying capacities Can not deal with vulnerability Use s Bill of Material compute creation cost settle on estimating choices

Slide 35

Representational Model Can join instability utilizes models to tackle choice issue utilizing conjectures Can be utilized to enlarge the capacities of Accounting models Use the request information to figure one years from now request Use the outcomes to settle on stock choices.

Slide 36

Optimization Systems Used to appraise the impacts of various choice option Based on enhancement models Can join vulnerability Assign deals drive to region Provide the best task plan

Slide 37

Suggestion Systems An illustrative model used to propose to the chief the best activity A prescriptive model used to recommend to the leader the best activity May consolidate an Expert System Applicant applies for individual advance utilize the framework to prescribe a choice

Slide 38

DSS Categories Support based DSS (Alter 1980) Data-based DSS Model-based DSS Structured Semi-structure Unstructured Model-based DSS Data-based DSS

Slide 39

DSS Categories Based on the way of the choice circumstance (Donovan & Madnick 1977) Institutional Culture of the association Regularly utilized Used by more than one individual Ad hoc One of kind One-time utilize Used by single individual

Slide 40

DSS Categories Based on number of clients (Keen 1980) Individual, Multi-singular, Group

Slide 41

How can data frameworks help administrative function? Appropriateness of DSS as far as undertaking structure, choice setting, and client. How is DSS adjusted to fit the necessities of assignment, setting, and client? Look at a choice circumstance of your decision and talk about sought DSS highlights. For instance: take a gander at the structuredness of choice errands, administration level, client sort, ect. Is DSS useful? Why? Or, then again Why not? Distinguish inconvenient impacts of DSS. Could DSS add to settling on a terrible choice and even to the destruction of an association?

Slide 42

Detrimental DSS Effects Design blemishes Inadequate comprehension of assignment or client Inadequate demonstrating of "reality" Inadequate comprehension of human data preparing limitations Can advance subjective predispositions!
