A weighted competitive strength assessment is generally analytically superior to an un$-$weighted strength assessment because:

d$.$ A weighted ranking measures each competitor on a scale of $1$ to $10$

b$.$ An un$-$weighted ranking doesn't use the overall ratings to draw conclusions regarding competitiveness

a$.$ All of the various measures of competitive strength are not equally important to a company's competitive strength

c$.$ Business process engineering is analytically superior and always results in a weighted assessment
