This is a table where we vote for the priorities of the bridge. For example: Stability/Strength, Appearance, Safety, Size and the Quality of Materials. Yes, size does matter.
Decision making matrix
This is a table where you tabulate the number of votes too see which is the most preferred bridge among the group.
As you can see, Design Option 3 has the most number of votes.
Final design: Just as we were about to start construction, we realised that design option 3 would be using too much resources and also make the bridge too heavy so we had to combine a few of our design to create a better bridge.
