DSS Characteristics
  • Supports individuals and teams
  • Used repeatedly and constantly
  • Two major components data and models
  • Web-based
  • Uses subjective, personal, and objective data
  • Has a simulation model
  • Used in public and private sectors
  • Has what-if capabilities
  • Uses quantitative and qualitative models

29
Working Definition of DSS
  • DSS
  • is an interactive, flexible, and adaptable CBIS,
    specially developed for supporting the solution
    of a unstructured management problem for improved
    decision making
  • utilizes data, provides easy user interface, and
    allows for the decision makers own insights
  • DSS
  • may utilize models
  • is built by an interactive process (frequently by
    end-users)
  • supports all the phases of the decision making
  • may include a knowledge component
  • Central Issue in DSS
  • support and improvement of decision making

30
Capabilities of DSS
  • Provide support in semi-structured and
    unstructured situations, includes human judgment
    and computerized information
  • Support for various managerial levels
  • Support to individuals and groups
  • Support to interdependent and/or sequential
    decisions
  • Support all phases of the decision-making process
  • intelligence, design, choice ( implementation)
  • Support a variety of decision-making processes
    and styles

31
Capabilities of DSS
  • Are adaptive
  • Have user friendly interfaces
  • Goal
  • improve effectiveness of decision making
  • The decision maker controls the decision-making
    process
  • End-users can build simple systems
  • Utilizes models for analysis
  • Provides access to a variety of data sources,
    formats, and types

32
Capabilities of DSS
  • Decision makers can make better, more consistent
    decisions in a timely manner

33
DSS Components
  • Data Management Subsystem
  • Model Management Subsystem
  • Knowledge-based (Management) Subsystem
  • User Interface Subsystem
  • The User

34
DSS Classifications
  • Text-oriented DSS
  • Database-oriented DSS
  • Spreadsheet-oriented DSS
  • Solver-oriented DSS
  • Rule-oriented DSS
  • Compound DSS

36
Evolution of EIS
  • DSS and ODSS
  • 1980s
  • Executive Information Systems
  • 1995s
  • Everybodys Information Systems
  • Enterprise Information Systems

37
Executive Information System (EIS)
  • A computer-based system that serves the
    information needs of top executives
  • Provides rapid access to timely information and
    direct access to management reports
  • Very user-friendly, supported by graphics
  • Provides exceptions reporting and "drill-down"
    capabilities
  • Easily connected to the Internet
  • Drill down

38
Executives Role and Their Information Needs
  • Decisional Executive Role (2 Phases)
  • Identification of problems and/or opportunities
  • The decision of what to do about them
  • Flow chart and information flow
  • Use phases to determine executives information
    needs

39
Methods for Finding Information Needs
  • Wetherbe's Approach
  • Structured Interviews
  • IBM's Business System Planning (BSP)
  • Critical Success Factors (CSF)
  • Ends/Means (E/M) Analysis
  • Prototyping
  • Watson and Frolick's Approach
  • Asking (interview approach)
  • Deriving the needs from an existing information
    system
  • Synthesis from characteristics of the systems
  • Discovering (Prototyping)
  • Ten methods
  • Other Methods

40
Characteristics of EIS
  • Drill down
  • Critical success factors (CSF)
  • Status access
  • Analysis
  • Exception reporting
  • Colors and audio
  • Navigation of information
  • Communication

41
Critical Success Factors (CSF)
  • Monitored by five types of information
  • Key problem narratives
  • Highlight charts
  • Top-level financials
  • Key performance indicators (KPI)
  • Detailed KPI responsibility reports

42
Characteristics and Benefits of EIS
  • Quality of information
  • Flexible, correct, timely, relevant, complete,
    validated
  • User interface
  • GUI, user-friendly, secure access, quick
    response, mobile accessibility, reliable, easy
    input, quick retrieval, tailored, self-help menu
  • Technical capability provided
  • Global information, email, external data, written
    interpretations, hypertext hypermedia, ad hoc
    analysis, multidimensional, hierarchical,
    graphics text, management-by-exception reports,
    trends deviations, historical current data,
    critical success factors, forecasting, drill
    down, tracking of critical data
  • Benefits
  • Attainment of organizational objectives,
    productivity, quality of decision making,
    competitive advantage, time saving, communication
    capacity quality, better organization control,
    anticipation of problems opportunities,
    planning, search for cause of a problem, needs of
    executives

43
Comparison of EIS and DSS
  • Focus
  • EIS Status access, drill down
  • DSS Analysis, decision support
  • Typical users
  • EIS Senior executives
  • DSS Analysts, professionals, managers
  • Impetus
  • EIS Expediency
  • DSS Effectiveness
  • Application
  • EIS Environmental scanning, performance
    evaluation, identification of problems and
    opportunities
  • DSS Diversified areas where managerial decisions
    are made

44
Comparison of EIS and DSS
  • Decision support
  • EIS Indirect support, mainly high-level and
    unstructured decisions and policies
  • DSS Supports semi-structured and unstructured
    decision making, ad hoc decisions, and some
    repetitive decisions
  • Type of information
  • EIS News items, external information on
    customers, competitors, and the environment
    scheduled and demand reports on internal
    operations
  • DSS Information supporting specific situations
  • Principal use
  • EIS Tracking and control, opportunity
    identification
  • DSS Planning, organizing, staffing, and
    controlling

45
Comparison of EIS and DSS
  • Adaptability to individual users
  • EIS Tailored to the decision-making style of
    each individual executive, offers several options
    of outputs
  • DSS Permits individual judgments, what-if
    capabilities, some choice of dialog style
  • Graphics
  • EIS A must
  • DSS Important part of many DSS
  • User-friendliness
  • EIS A must
  • DSS A must if no intermediaries are used

46
Comparison of EIS and DSS
  • Processing of information
  • EIS Filters and compresses information, tracks
    critical data and information
  • DSS EIS triggers questions, answers are worked
    out by DSS and fed back into EIS
  • Supporting detailed information
  • EIS Instant access to the supporting details of
    any summary (drill down)
  • DSS Can be programmed into the DSS but usually
    is not
  • Model base
  • EIS Limited built-in functions
  • DSS The core of the DSS

47
Comparison of EIS and DSS
  • Construction
  • EIS By vendors or IS specialists
  • DSS By users, either alone or with specialists
    from IS department
  • Hardware
  • EIS Mainframe, RISC workstations, LANs, or
    distributed systems
  • DSS Mainframe, RISC workstations, PCs, or
    distributed systems

48
Comparison of EIS and DSS
  • Nature of software packages
  • EIS Interactive, easy access to multiple
    databases, online access, sophisticated DBMS
    capabilities, complex linkages
  • DSS Large computational capabilities, modeling
    languages and simulation, application and DSS
    generators
  • Nature of information
  • EIS Displays pre-generated information about the
    past present, creates new information about the
    past, present future
  • DSS Creates new information about the past,
    present future
