Decision Making and Decision Support Systems
Introduction to Decision Making
- Definition of Decision: A choice among alternatives based on facts and judgments.
- Types of Decisions:
- Well-Structured: Simple, clear alternatives.
- Wicked Problems: Unique, complex issues with no clear solutions.
- Decision Support Systems (DSS):
- Designed for poorly structured problems.
- Provide frameworks for analyzing alternatives.
Rational Decision Making
- Definition of Rationality: Derives from logical reasoning.
- Information Needs for Rational Decisions:
- Must include data about alternatives and conditions.
- Economic rationality is key: optimize costs/profits.
- Types of Rationality in Decision Making (Figure 2.2):
- Procedural Rationality: Logistics of decision-making processes.
- Economic, Political, and Social (Ethical) Rationality: Evaluating choices based on different criteria.
- Legal Rationality: Ensures decisions comply with legal standards.
Technical Considerations
- Technical Rationality: Decision-making should align with goals.
- Importance of including technical criteria in DSS for effective evaluation.
Bounded Rationality and Satisficing
- Bounded Rationality: Decision-makers operate with limitations in data and methods.
- Satisficing rather than optimizing decisions.
- Muddling Through Theory: Preference for incremental changes over bold decisions.
- Organizational Limitations: Issues like corporate culture and cooperation can impact decision-making capabilities.
Nature of Managers
- Managers prefer informal, flexible decision processes:
- Use verbal versus written communication for efficiency.
- Require access to sources of information.
- DSS Design Implications:
- Must facilitate integration of communication and variety of data access.
Appropriate Decision Support
- DSS as Electronic Memory: Capture and recreate decision processes.
- Bias in Decision Making: Ensure systems help mitigate selective information perception.
- Structured information presentation can help avoid overwhelming users.
- Phases of Information Processing: Sensation, attention, and perception.
- Decision-makers filter information based on relevance and task goals.
- Novices require structure, while experts require flexibility in decision processes.
Group Decision Making
- Benefits: Collective intelligence can generate diverse solutions.
- Challenges: Group dynamics may lead to pressure and incomplete analyses.
- Improving group decision processes through guided brainstorming and time limitations.
Intuition, Qualitative Data, and Decision Making
- Significant decisions often rely on intuition despite available data.
- Integrated Decision-Making Style: Utilizes both analytic and intuitive processes to manage complexity.
Business Intelligence (BI)
- Definition of BI: Systematic approach to provide timely data insights for decision making.
- Importance: Essential for navigating competitive business landscapes and regulatory environments.
- Analytics Role in Decision Making: Crucial for devising strategies that set companies apart.
Competitive Intelligence (CI)
- Goal of CI: Enhance understanding of the business environment for strategic decision making.
- Importance of multi-source data gathering for early identification of threats/opportunities.
Conclusion
- This chapter provided foundational theories on decision making to be explored further in the context of DSS implementation and design.
