This is an extensive study of two famous, influential and iconic leaders in the world of business, Jack Welch and Ratan Tata. They served in the corporate world as effective and successful leaders for more than 20 years. We found differences in their leadership styles across different cultures. We also determined key common elements contributing to their success. We isolated two contrasting styles of leadership from Jack Welch’s simplicity and speed in decision making to Ratan Tata’s ‘heroic’ corporate expansion. We suggest a list of recommendations for MBA students aspiring to be authentic leaders of the future.
