Suppose a strategic plan is in place and the company discovers that it has failed to achieve the sales and profit increase it was expecting. When the results are reported, senior executives begin to blame other departments. Several senior executives have said privately that it might be better to scrap the plan and start over so that the top team can come to agreement. What strategic issues are involved. Would you agree that the current plan should be scrapped? Do you think it is better to concentrate on one source of competitive advantage (cost versus differentiation versus speed) or to nurture all three in a firm's operation? Cite strategic concepts to defend your answer.
