How Does a Decision Matrix Work?
A decision matrix works by listing your options as rows on a table and your evaluation criteria as columns. Each cell of the matrix is then filled with a score that reflects how well each option meets each criterion. These scores are usually numerical and can be weighted to reflect the importance of each criterion to the overall decision.
When to Use a Decision Matrix?
A decision matrix is most effective when facing decisions that involve multiple criteria and alternatives. Examples include selecting a new
vendor, choosing the best location for a new branch, or deciding on the best marketing strategy. It is especially helpful when you need to justify your decisions to stakeholders or when the decision will have significant long-term impacts.
Steps to Create a Decision Matrix
1.
Identify Options: List all the alternatives you are considering.
2.
Determine Criteria: Establish the factors that will influence your decision. Common criteria include cost, quality, and
time frame.
3.
Assign Weights: If certain criteria are more important than others, assign weights to reflect their significance.
4.
Rate Each Option: Score each alternative against each criterion.
5.
Calculate Weighted Scores: Multiply the scores by their respective weights and sum them up for each option.
6.
Analyze Results: The option with the highest total weighted score is usually the best choice.
Example of a Decision Matrix
Consider a company deciding on a new software tool. The criteria might include cost, user-friendliness, and customer support. Here's a simplified matrix: Option
Cost
User-Friendliness
Customer Support
Total Score
Software A
8
7
9
24
Software B
7
9
8
24
Software C
9
6
7
22
In this case, both Software A and Software B have the same total score. Further analysis or additional criteria may be needed to make a final decision.

Conclusion
A decision matrix is an invaluable tool in the arsenal of any business aiming to make well-informed, rational decisions. By providing a clear framework to evaluate multiple options against a set of criteria, it helps in minimizing biases and making choices that align with the company's goals and objectives. Whether you're selecting a new supplier, deciding on a marketing strategy, or choosing a location for expansion, a decision matrix can be extremely beneficial.
