Decision Maker Tool

What is the WADM Method?

WADM (Weighted Average Decision Matrix) is a quantitative decision-making tool. By assigning weights to different criteria and calculating the weighted total score, it helps users make more rational choices in complex situations.

Core Steps

1. Identify criteria: List all relevant factors based on your decision goal (e.g., salary, commute time, etc.).
2. Assign weights: Allocate a weight to each criterion (total 100%) to reflect its importance.
3. Score & calculate: Rate each option for every criterion (e.g., 0-10), then calculate the weighted total.
4. Choose the option with the highest total score as the optimal solution.

Typical Scenarios

• Career choice: Compare jobs by salary, growth, etc.
• Business decisions: e.g., project evaluation, vendor selection.
• Personal life: e.g., buying a house, choosing education paths.

Advantages

• Structured analysis for transparent decisions.
• Flexible weights for different priorities.

Limitations

• Subjective weights and scores; results depend on input.
• Static assumptions; re-evaluate if circumstances change.
