Porter stressed the idea that only one strategy should be adopted by a firm and failure to do so will result in “stuck in the middle” scenario. He discussed the idea that practising more than one strategy will lose the entire focus of the organization hence clear direction of the future trajectory could not be established. The argument is based on the fundamental that differentiation will incur costs to the firm which clearly contradicts with the basis of low cost strategy and on the other hand relatively standardised products with features acceptable to many customers will not carry any differentiation hence, cost leadership and differentiation strategy will be mutually exclusive. Two focal objectives of low cost leadership and differentiation clash with each other resulting in no proper direction for a firm. In particular, Miller questions the notion of being "caught in the middle". He claims that there is a viable middle ground between strategies. Many companies, for example, have entered a market as a niche player and gradually expanded. According to Baden-Fuller and Stopford (1992) the most successful companies are the ones that can resolve what they call "the dilemma of opposites". Furthermore, Reeves and Routledge's (2013) study of entrepreneurial spirit demonstrated this is a key factor in organisation success, differentiation and cost leadership were the least important factors.
