IBM doesn't like drama - and it proved that with its appointment of Virginia Rometty as its new CEO earlier this week.

In taking the job, Rometty replaces a somewhat reserved figure, CEO Sam Palmisano, who did not seek the stage in Washington or Silicon Valley. But when it came to strategy, Palmisano brought big changes to IBM and set clear directions for the company through 2015.

Palmisano's influence on IBM's future will outlast his tenure by years, which helps to explain why IBM saw Rometty as an ideal candidate for the job.

Rometty, senior vice president and group executive for sales, marketing and strategy, is following a tough act. She will take over the company on January 1, while Palmisano will continue as board chairman and remain a powerful presence.

Overseas interests

Chris Ambrose, an analyst at Gartner Inc, believes that IBM takes a different of view of leadership roles than some of its competitors and puts the IBM brand - not any one individual - on centre stage. With Rometty, the company is tapping someone who understands where the company is moving, who "understands and accepts that strategy," said Ambrose.

Rometty has been at IBM since 1981, when she was a systems engineer.

Palmisano, appointed CEO in 2002, redefined IBM as a "globally integrated enterprise," meaning a firm that "that locates operations and functions anywhere in the world based on the right cost, the right skills, and the right business environment" and is completely integrated.

Palmisano increased IBM's overseas hiring, at the expense of North American jobs, and put a lot of attention on what the company calls "growth markets." It considers those markets to be every place in the world but North America and western Europe.

Smarter Planet

In 2006, IBM said 16% of its revenue came from growth markets, By last year, that figure had reached 21%. By 2015, the percentage of revenue the company expects to earn in growth markets will approach 30%.

Under Palmisano, IBM has already outlined a corporate strategy through 2015 that also calls for continued development of "higher value" services and software, and an entirely new category of services and software it calls Smarter Planet.

Last year, IBM announced a plan to spend $20 billion to buy companies through 2015, more money than it spent in the previous 10 years. Many of those acquisitions will be aimed at business analytics, cloud services and related software.

In her role at IBM, Rometty had a role in shaping those strategies, say analysts.

Short-term stability

"I would not expect to see a huge amount of change in the short term, but she is an intelligent executive and I would expect her to see her put her own stamp on the company," said Charles King, an analyst at Pund-IT.

The fact that under Palmisano, IBM's workforce grew overseas and decreased in the US tells something about world today.

In 2006, IBM employed 127,000 workers in the US, a figure that dropped to 105,000 by 2010, the last time the company publicly reported its US-based employment.

Lee Conrad, that national coordinator of the [email protected], which is part of the Communications Workers of America union, said he expects "IBM US employees will continue losing jobs as work is shifted offshore." The Alliance estimates that IBM's US workforce is now at about 98,000.

"The decline in US IBM employee population has been steep under Palmisano and Rometty," said Conrad.

Worldwide, it's a different story: IBM's employment has been growing and is now at about 436,000 people.
