Porter approach

According to Porter, these strategies are mutually exclusive and the firm must select one approach to the exclusion of all others.: 12 Firms that try to be all things to all people can present a confusing market position which ultimately leads to below-average returns. Any ambiguity about the firm's approach is a recipe for "strategic mediocrity" and any firm that tries to pursue two approaches simultaneously is said to be "stuck in the middle" and destined for failure.
