<p>Ginni Rometty, who has been CEO at IBM for a year and a half, is making two big changes in the upper echelons of her management teams; she is swapping the head of corporate strategy and the head of its Systems and Technology Group, and it is presumably to get better results than IBM showed in its first quarter of 2013 in its systems, storage, and chip businesses.</p><p>The very small game of musical chairs may also have something to do with a rumored spinoff of all or a portion of IBM's System x x86 server business to Chinese PC and server maker Lenovo Group. IBM has not confirmed or denied those rumors, and Lenovo merely said to the Hong Kong Exchange where its stock trades that it was in talks with someone to possibly buy something.</p><p>Rometty announced the executive changes in an email sent out on Wednesday, and it sees Rod Adkins, who has been running the Systems and Technology Group (well, sort of, and El Reg will explain in a moment) for several years, exchange jobs with Tom Rosamilia, who has worked for Adkins running IBM's System z mainframe and Power Systems businesses. This is what the email to IBMers from their CEO said:Effective today, Rod Adkins will become senior vice president, Corporate Strategy, reporting to me. Rod takes on this role at an important time. As you know, our strategic beliefs about the new computing model, new markets and clients, and the evolution of our own company our continuous transformation are really taking hold.</p><p>We are in a leadership position, and we will extend it by continuing to act aggressively on these beliefs. Rod comes to his new position with a wealth of leadership experience and insight in both business and technology. We will look to him to bring that leadership and insight to bear in helping to shape our long-term enterprise strategy.Succeeding Rod as the leader of Systems &amp; Technology Group will be Tom Rosamilia, reporting to Steve Mills. Tom has a rich background in all aspects of systems, from Power and mainframe to WebSphere. Tom will help the STG team further accelerate its transformation in pursuit of high-value opportunities.</p><p><a href="http://www.theregister.co.uk/2013/04/24/ibm_server_strategy/">Keep reading...</a></p>
