Chairman, President, CEO
Ginni Rometty has laid the foundation for IBM sales growth with $4 billion in cloud, mobile and analytics investments that she promises will deliver $40 billion in annual revenue for those lines of business in 2018. Rometty told partners earlier this year that transformations are only clear when they are told in revisionist history. For our money, the transformation at IBM is already in view.
