Chapter 10: Decision Support Systems
the manufacturing
MIS subsystems and outputs are used to monitor and control the flow of materials, products, and services through the organization
Define the term DSS and briefly describe the basic capabilities of a DSS
a decision support system (DSS) is an organized collection of people, procedures, software, databases, and devices used to help make decisions that solve problems (used at all levels). The focus of a DSS is on decision-making effectiveness regarding unstructured or semistructured business problems. A DSS provides rapid access to information, handles large amounts of data from different sources, provides report and presentation flexibility, offers both textual and graphical orientation, supports drill-down analysis, and performs complex, sophisticated analyses.
the group consensus
approach forces members of a decision making group to reach a unanimous decision
structured decisions
are ones where the variables that comprise the decision are known and can be measured quantitatively
decision support systems
are used for operational, tactical, and strategic decision making
subsystems for the marketing MIS and their outputs help marketing managers and executives to
develop plans for future products
a typical DSS includes many components such as the ________ _______ that allows decision makers to easily access and manipulate the DSS and to use common business terms and phrases
dialogue manager
the inference engine
is NOT a component of the typical DSS (components: database, user interface, model base)
the ability to use internal data stored in the computer system
is a characteristic of a MIS
the ability to provide to provide easy access to financial data through use of a corporate intranet to access corporate Web pages
is a function of a financial MIS
delphi approach
is a structured, interactive, iterative decision-making method that relies on input from a panel of reports
a profit center
is an independent business unit that is treated as a distinct entity enabling its revenues and expenses to be determined and its profitability to be measured
a key-indicator report
is the management report that summarizes previous day's critical activities and is typically available at the start of each workday
the design stage
is the second stage in the problem solving process during which alternative solutions to the problem are developed and their feasibility is evaluated
the goal of computer integrated manufacturing (CIM)
is to tie together all aspects of production, including order processing, product design, manufacturing and quality control, and shipping
teleconferencing
is used when the decision frequency is low and the location of group members is distant
an advantage of using the nominal group technique is that
it encourages participation from everyone
the choice stage
of the problem solving process requires selecting a course of action
the performance of design support systems is typically a function of design quality, decision-making speed, and
problem complexity
exception
reports are management reports that are automatically produced when a situation is unusual or requires management action
developers of group support systems
try to build on the advantages of individual support systems while adding new approaches unique to group decision making
a marketing MIS
uses data gathered from both internal and external sources to provide reporting and aid decision making in areas of product development, distribution, pricing, and promotions
the most significant internal data sources for a MIS are the organization's
various TPS and ERP systems and related databases
the focus of a DSS is on decision-making _____________ when faced with unstructured or semistructured business problems
effectiveness
an effective human resource MIS
enables an organization to keep personnel costs at a minimum while serving the required business processes needed to achieve corporate goals
Identify and briefly describe the various kinds of reports frequently produced by a MIS
1) Scheduled reports: produced periodically, such as daily, weekly, or monthly (key-indicator report summarizes the previous day's critical activities) 2) Demand reports: developed to provide certain information upon request 3) Exception reports: automatically produced when a situation is unusual or requires management action. Trigger points should be set carefully 4) Drill-down reports: provide increasingly detailed data about a situation
Briefly describe the five stage decision making process
1) identify the problem and uncertainties 2) obtain information 3) make predictions about the future 4) make decisions by choosing among alternatives 5) implement the decision, evaluate performance, and learn
