To choose the best concept, all three concepts are rated based on the requirements derived from the analysis phase. This way the best concept will be the concept that fulfills the users' needs best. 

​

Every requirement is in this case considered equally important. Every requirement is rated for the three concepts on a scale 0 to 4.

​

As can be derived from the table on the left, concept three fulfills the requirements best, with concept 2 being a close second.

​

Because concepts 2 and 3 both scored well on the concept selection and because the participants agreed on both concepts, we decided to combine both concepts in one final product.
