Decision Matrix

A method to evaluate and compare multiple solutions based on defined criteria and weights, assisting in the selection of the best solution.

About

A Decision Matrix is a tool used to evaluate and prioritize options based on specific criteria. By assigning weights and scores to different factors, it facilitates objective decision-making. Decision Matrices are valuable in product development, project management, and strategic planning, where complex decisions need to be made. By providing a structured approach to evaluating alternatives, they help teams align on priorities, reduce bias, and make informed decisions that align with organizational goals.

Suitable for

  • Rational selection of the best solution
  • Comparison of different proposals
  • Comparison of new proposals with existing solutions

Procedure

1

Identify the problem

Clearly define the problem or decision you need to make. This step is crucial, as it will help you understand the context and the factors that need to be considered while making the decision.

2

List the criteria

Identify the most important criteria (factors) that need to be addressed in the decision-making process. These criteria should be relevant, specific, and measurable. It’s recommended to limit the number of criteria between 5 and 10 to make the decision matrix easier to manage.

3

Assign weights

Assign a weight to each criterion to signify its importance in the decision-making process. The weights can be assigned on a scale of 1 to 10, where 1 represents the least important criterion and 10 represents the most important criterion. Ensure that the sum of all weights is equal to 1 (or 100%, if using percentages).

4

Identify the alternatives

List out all possible alternatives or solutions that could potentially address the problem. These alternatives should cover a wide range of options and should be viable in the given context.

5

Evaluate each alternative

For each alternative, evaluate its effectiveness in addressing each of the criteria. The evaluation can be done using a scale of 1 to 10, where 1 represents the least effective solution and 10 represents the most effective solution. Rate the performance of each alternative on each criterion, thus creating a matrix.

6

Calculate the weighted scores

Multiply the rating of each alternative for a particular criterion by the weight assigned to that criterion. Repeat this for all criteria, and then sum up the weighted scores for each alternative. The result will be the total weighted score for each alternative.

7

Compare and choose

Compare the total weighted scores for each alternative. The alternative with the highest total weighted score should be considered as the most suitable solution to the problem, as it best satisfies the chosen criteria. Make a decision based on the results of the decision matrix, taking into consideration any additional factors, if necessary.

8

Review and adjust

Review the decision matrix results, and critically analyze if the outcome makes sense in the given context. If necessary, adjust the weights, ratings, or even reevaluate the criteria, and repeat the process until you find a satisfactory and well-supported decision.
