Using a Decision Matrix

A decision matrix is used to compare ideas against one another, using specific criteria. To use the decision matrix, we follow the following steps.


Step 1: List down all the ideas.

Example

What material would be best for creating models of puzzle pieces?

Idea 1: Modeling clay 

Idea 2: Caramel cubes

Idea 3: Dice

Idea 4: Centimetre cubes 

Idea 5: Foam blocks 


Step 2: Identify criteria which will be used to evaluate the ideas. 

Example.

  • Cost
  • Reusability
  • Geometry
  • Connection
  • Cleanliness
  • Resilience
  • Testability


Step 3: A grading scale must be developed to assign values for each criteria category.
