6Section I
- Decision Support in Business
7Business and Decision Support
- To succeed, companies need information systems
that can support the diverse information and
decision-making needs of their managers and
business professionals.
8Business and Decision Support (continued)
- Information, Decisions, Management
- The type of information required by decision
makers is directly related to the level of
management and the amount of structure in the
decision situations.
9Business and Decision Support (continued)
10Business and Decision Support (continued)
- Information Quality
- Timeliness
- Provided WHEN it is needed
- Up-to-date when it is provided
- Provided as often as needed
- Provided about past, present, and future time
periods as necessary
11Business and Decision Support (continued)
- Information Quality (continued)
- Content
- Free from errors
- Should be related to the information needs of a
specific recipient for a specific situation - Provide all the information that is needed
- Only the information that is needed should be
provided - Can have a broad or narrow scope, or an internal
or external focus - Can reveal performance
12Business and Decision Support (continued)
- Information Quality (continued)
- Form
- Provided in a form that is easy to understand
- Can be provided in detail or summary form
- Can be arranged in a predetermined sequence
- Can be presented in narrative, numeric, graphic,
or other forms - Can be provided in hard copy, video, or other
media.
13Business and Decision Support (continued)
14Business and Decision Support (continued)
- Decision Structure
- Structured decisions
- Involve situations where the procedures to be
followed can be specified in advance - Unstructured decisions
- Involve situations where it is not possible to
specify most of the decision procedures in advance
15Business and Decision Support (continued)
- Decision structure (continued)
- Semistructured decisions
- Some decision procedures can be specified in
advance, but not enough to lead to a definite
recommended decision
16Business and Decision Support (continued)
- Amount of structure is typically tied to
management level - Operational more structured
- Tactical more semistructured
- Strategic more unstructured
17Decision Support Trends
- The growth of corporate intranets, extranets and
the Web has accelerated the development and use
of executive class information delivery
decision support software tools to virtually
every level of the organization.
18Management Information Systems
- The original type of information system
- Produces many of the products that support
day-to-day decision-making - These information products typically take the
following forms - Periodic scheduled reports
- Exception reports
- Demand reports and responses
- Push reports
19Management Information Systems (continued)
- Management reporting alternatives
- Periodic scheduled reports
- Prespecified format
- Provided on a scheduled basis
- Exception reports
- Produced only when exceptional conditions occur
- Reduces information overload
20Management Information Systems (continued)
- Management reporting alternatives (continued)
- Demand reports and responses
- Available when demanded.
- Ad hoc
- Push reports
- Information is sent to a networked PC over the
corporate intranet. - Not specifically requested by the recipient
21Online Analytical Processing
- Enables managers and analysts to interactively
examine manipulate large amounts of detailed
and consolidated data from many perspectives - Analyze complex relationships to discover
patterns, trends, and exception conditions - Real-time
22Online Analytical Processing (continued)
- Involves..
- Consolidation
- The aggregation of data.
- From simple roll-ups to complex groupings of
interrelated data - Drill-Down
- Display detail data that comprise consolidated
data
23Online Analytical Processing (continued)
- Slicing and Dicing
- The ability to look at the database from
different viewpoints. - When performed along a time axis, helps analyze
trends and find patterns
24Decision Support Systems
- Computer-based information systems that provide
interactive information support during the
decision-making process - DSSs use
- Analytical models
- Specialized databases
- The decision makers insights judgments
- An interactive, computer-based modeling process
to support making semistructured and unstructured
business decisions
25Decision Support Systems (continued)
- Designed to be ad hoc, quick-response systems
that are initiated and controlled by the decision
maker - DSS Models and Software

three-dimensional graphic forms - Helps discover patterns, links, and anomalies
29Using Decision Support Systems
- An interactive modeling process
- Four types of analytical modeling
- What-if analysis
- Sensitivity analysis
- Goal-seeking analysis
- Optimization analysis
30Using Decision Support Systems (continued)
- What-If Analysis
- End user makes changes to variables, or
relationships among variables, and observes the
resulting changes in the values of other variables
31Using Decision Support Systems (continued)
- Sensitivity Analysis
- A special case of what-if analysis
- The value of only one variable is changed
repeatedly, and the resulting changes on other
variables are observed - Typically used when there is uncertainty about
the assumptions made in estimating the value of
certain key variables
32Using Decision Support Systems (continued)
- Goal-Seeking Analysis
- Instead of observing how changes in a variable
affect other variables, goal-seeking sets a
target value (a goal) for a variable, then
repeatedly changes other variables until the
target value is achieved
33Using Decision Support Systems (continued)
- Optimization Analysis
- A more complex extension of goal-seeking
- The goal is to find the optimum value for one or
more target variables, given certain constraints
34Using Decision Support Systems (continued)
- Data Mining for Decision Support
- Software analyzes vast amounts of data
- Attempts to discover patterns, trends,
correlations - May perform regression, decision tree, neural
network, cluster detection, or market basket
analysis
35Executive Information Systems
- EISs combine many of the features of MIS and DSS
- Originally intended to provide top executives
with immediate, easy access to information about
the firms critical success factors - Alternative names
- Enterprise information systems
- Executive support systems
36Executive Information Systems (continued)
- Features of an EIS
- Information presented in forms tailored to the
preferences of the users - Most stress use of graphical user interface and
graphics displays - May also include exception reporting and trend
analysis
37Enterprise Portals and Decision Support

and other technologies that gives all intranet
users and selected extranet users access to a
variety of internal external business
applications and services
