Calculating quantitative attractiveness ratings for the industries a company has
diversified into involves:
A. determining each industry’s key success factors, calculating the ability of the
company to be successful on each industry KSF, and obtaining overall measures of the
firm’s ability to compete successfully in each of its industries based on the combined
KSF ratings.
B. determining each industry’s competitive advantage factors, calculating the ability of
the company to be successful on each competitive advantage factor, and obtaining
overall measures of the firm’s ability to achieve sustainable competitive advantage in
each of its industries based on the combined competitive advantage factor ratings.
C. selecting a set of industry attractiveness measures, weighting the importance of each
measure, rating each industry on each attractiveness measure, multiplying the industry
ratings by the assigned weight to obtain a weighted rating, adding the weighted ratings
for each industry to obtain an overall industry attractiveness score, and using the overall
industry attractiveness scores to interpret the attractiveness of all the industries, both
individually and as a group.
D. rating the attractiveness of each industry’s strategic and resource fits, summing the
attractiveness scores, and determining whether the overall scores for the industries as a
group are appealing or not.
E. identifying each industry’s average profitability, rating the difficulty of achieving
average profitability in each industry, and deciding whether the company’s prospects for
above-average profitability are attractive or unattractive, industry by industry.
