The findings reveal that, all of the outlined strategies do matter to the sales of stated MNCs but promotional gifts and sponsored trips they really work much than the rest of strategies considered, in long run only for Abbott Pakistan, while the differentiated and un-differentiated strategies for GSK and product development and establishing the brands for Aventis are revealed as the best most options for maximizing sales.
