Concept Screening
The concepts arrived upon using the morphological chart are then screened against each other and against the customer needs. This is done as a preliminary decision matrix to see which concepts are going to be further analyzed.

As a result of detailed analysis, concept one was chosen to be the most compatible with the farmer’s needs. Also, model 1 supplied sufficient methods of the wants form the specification table.
This is one way of selecting a concept where no multiplying factors are used. However, another way includes the assignment of multiplying factors to the design criteria in accordance to each ones relative importance. Hence, different scores could have been obtained for the previous example, and a different concept may have been chosen.
