A consequence table is a multi-objective decision-support tool that helps in structuring and comparing different options based on their expected outcomes across various criteria.
As defined by the provided information, consequence tables are multi-objective decision-support tools that deal explicitly with trade-offs. They are designed to make complex choices clearer by presenting the results or 'consequences' of each potential course of action in a structured format.
Core Elements of a Consequence Table
The provided reference highlights three core elements that are compactly reported in a consequence table:
- Alternatives: These are the different options, choices, or courses of action being considered.
- Expected Consequences: For each alternative, these are the anticipated outcomes or results under specific objectives or criteria.
- Trade-offs: Consequence tables make the compromises or exchanges between different objectives visible, allowing decision-makers to see what they gain or lose by choosing one alternative over another.
How Consequence Tables Work
A consequence table typically presents alternatives in rows and the relevant objectives or criteria in columns. The cells within the table show the expected consequence of each alternative with respect to each specific criterion.
This structure allows decision-makers to systematically evaluate how well each option performs across all important factors and to clearly see where one option might be better in one area but worse in another, thereby revealing the inherent trade-offs.
Example Structure
Imagine a simple decision about choosing between two different project approaches (Alternative A vs. Alternative B) based on Cost and Time. A consequence table might look like this:
| Alternative | Objective: Cost | Objective: Time |
|---|---|---|
| Alternative A | $50,000 | 6 Months |
| Alternative B | $75,000 | 4 Months |
In this simplified example, the table compactly reports the expected consequences ($50,000, 6 Months for A; $75,000, 4 Months for B) for each alternative across the chosen objectives. It immediately highlights a trade-off: Alternative A is cheaper but takes longer than Alternative B.
Practical Benefits
Using consequence tables offers several practical benefits in decision-making:
- Clarity: Organizes complex information in an easy-to-read format.
- Transparency: Makes the expected outcomes and trade-offs explicit and visible to all stakeholders.
- Systematic Comparison: Allows for a structured comparison of alternatives against defined criteria.
- Focus on Trade-offs: Explicitly helps decision-makers understand the compromises involved in choosing one option over others.
By presenting alternatives, their expected consequences, and the resulting trade-offs in a single view, consequence tables serve as valuable tools for supporting well-informed decisions, particularly in situations involving multiple conflicting objectives.
