Step #5 -- Compare each of the alternatives to the baseline concept

First, you should pick a baseline design (leftmost column). The baseline is typically the current design or favored design.

Ideally, the baseline design is a "fall back position"; if the new design fails for any reason, you can always go back to the old design.

Compare the design alternatives using the scale:

• +3 = Far Better than Baseline
• +2 = Much Better than Baseline
• +1 = Better than Baseline
• 0 = Same as Baseline
• -1 = Worse than Baseline
• -2 = Much Worse than Baseline
• -3 = Far Worse than Baseline
