Concept Selection
See above configuration for final selection. These
options were deemed to be the best selections using the
criteria and selection procedures listed earlier.
Reflect on the Results and the Process
Going through the decision making process allowed us
to find the optimal solution to our design challenge. The
concept we have settled on agrees with our gut intuition
and research, which gives us confidence to move forward
with our design.
