MIS-12 Flashcards
1
Q
Types of Decisions in an Organization
A
- Structured decisions
- Semistructured decisions
- Unstructured decisions
2
Q
Structured decisions
A
- Can be automated because a well-defined standard operating procedure exists for these types of decisions
- Known as programmable tasks
3
Q
Semistructured decisions
A
- Include a structured aspect that benefits from information retrieval, analytical models, and information systems technology
4
Q
Unstructured decisions
A
- One-time decisions with no standard operating procedure
- Decision maker’s intuition plays an important role as information technology offers less support for the decisions
5
Q
Organizational Levels
A
- Strategic Management
- Tactical Management
- Operational Management
6
Q
Management Support Systems (MSSs)
A
- Different types of information systems that have been developed to support certain aspects and types of decisions
- Each type is designed with unique goals and objectives
7
Q
Phases of Decision Making
A
- Intelligence phase
- Design phase
- Choice phase
- Implementation phase
8
Q
Intelligence Phase
A
- Decision maker examines the organization’s environment for conditions that need decisions
- Data is collected from a variety of sources and processed
9
Q
Design Phase
A
- Defines the criteria for a decision
- Generates alternatives for meeting the criteria
- Defines associations between the criteria and the alternatives (Requires understanding how each alternative affects the criteria)
- Information technology does not support this phase of decision making
10
Q
Choice Phase
A
- Selecting the best and most effective course of action is from the alternatives
- Analyzing each alternative and its relationship to the criteria to determine whether it is feasible
11
Q
Decision support system (DSS)
A
- Helps sort through possible solutions to choose the best one for the organization
- Includes tools for calculating cost-benefit ratios
12
Q
Implementation Phase
A
- Organization devises a plan for carrying out the alternative selected in the choice phase and obtains the resources to implement the plan
- DSS does a follow-up assessment on how well a solution is performing
13
Q
Decision support system (DSS)
PART 2
A
-Interactive information system designed to assist decision makers in an organization
-Consist of:
Hardware
Software
Data
Mathematical and statistical models
14
Q
Requirements of Decision Support Systems
A
- Be interactive and incorporate the human element as well as hardware and software
- Use internal and external data
- Include mathematical and statistical models
- Support decision makers at all organizational levels
- Emphasize semistructured and unstructured tasks
15
Q
Components of Decision Support Systems
A
- Database
- Model base
