$1.$ The following three rating scales have been proposed to rate designers$$ quality in the best value selection process.

a$)$ Numerical rating from $1$ to $100$ with low being the lowest quality and $100$ being the best

b$)$ Color rating red, yellow, green, blue, with red being the lowest quality and blue being the best

c$)$ A descriptive method using the terms: poor, acceptable, good, very good and excellent

If asked which method is best, most students choose method $($a$).$ The most common defense of method $($a$)$ is that it is superior because it uses a numeric scale. Provide a critique of using method $($a$)$ and defend either method $($b$)$ or $($c$)$ as being superior.
