One of the major mistakes a firm can make during the transition to industry maturity is to which?

a. steer a middle course between low cost, differentiation, and focusing because such strategic compromises typically result in a firm ending up "stuck in the middle" with a fuzzy strategy and no competitive advantage
b. expand into foreign markets
c. attack weaker firms and try to capture some of their market share
d. purchase rival companies at bargain prices-this simply makes the company a bigger slow-growth company
e. dissolve its strategic alliances and partnerships
