Assignment 5 Flashcards
memorize
Programmed decision
made using a rule, procedure or qualitative method
easy to computerize using traditional information systems.
Non-programmed decision
decision that deals with unusual or exceptional situations
not easily quantifiable
basic kinds of reports produced by MIS
scheduled reports: produced periodically, such as daily, weekly or monthly
key-indicator report: summarize the previous day’s critical activities
demand report: developed to provide certain information upon request.
Exception report: a report automatically produced when a situation is unusual or requires management. action.
drill-down reports: provide increasingly detailed data about a situation
list and describe some other MIS
accounting MIS: provides aggregate information on account payable, account receivable, payroll and many other applications.
geographic information system: capable of assembling, storing, manipulating, and displaying geographically referenced information.
difference between MIS and DSS
the type of problem solved
the support given to user
the decision emphasis and approach
the type, speed, output and development of the system used.
the stages of problem solving
intelligence stage: identify and define potential problems or opportunities
design stage: develop alternative solutions to the problems and their feasibility
choice stage: select a course of action
problem solving:
includes and goes beyond decision making
includes implementation stage
monitoring stage:
decision makers evaluate the implementation.
decision making
This refers to the process of selecting the option from multiple alternatives. It is a part of problem solving but does not necessarily resolve the entire problem. Decision-making focuses on choosing a solution rather than implementing it.
Problem solving
This is a broader process that includes identifying a problem, analyzing a possible solution, making a decision and implementing and evaluating a solution. It aims at completely resolving the issue rather than just selecting a problem.
define decision support system
what are its characteristics
-Organized collection of people, procedures, software, databases and devices used to help make decisions that solve problems
-characteristic of DSS are:
support for problem solving phases
support for various decision frequencies
support for various problem structures
support for various decision making levels
structured problems
A structured problems is one that is straightforward and requires known facts and relationships to resolve. These problems follow clear and defined process making them easier to analyze and to resolve. An example of a structured problem is an inventory management.
Unstructured problems
Unstructured on the other hand, is more complex, with unclear relationships, multiple possible solutions, and no predefined process for finding answers. Decision makers often do no know all the required information in advanced. An example of an unstructured problem is deciding the best location for a new manufacturing plant, as it involves many uncertain factors such as economic conditions, infrastructure, and workforce availability.
data driven DSS
performs qualitative analysis based on the computer’s database.
model drives DSS
performs mathematical and quantitative analysis
Components of DSS
the components of a DSS are a database and a model base and dialogue manager which allows decision makers to easily access and manipulate the DSS and to use common business terms and phrases.
what are the characteristics of an executive support system
Characteristics of ESS:
-Tailored to individual executives
-Easy to use
-Have dirll-down abilities
-support the need for external data
-can help situations that have a high level of uncertainty
-have a future orientations
Mobile commerce
Mobile commerce(m-commerce) is the use of mobile, and wireless devices to place orders and conduct business
difference between m-commerce and e-commerce
Mobile commerce(m-commerce) is the use of mobile, and wireless devices to place orders and conduct business
E-commerce can increase a company’s stock prices and market values
system development
system development is the process of creating and modifying an information system to meet business needs.
