26. Charlene Begley
After running GE Plastics for two years - and overseeing the first new polymer since the 1980s - Begley helped sell the unit to Saudi Basic Industries in May for $11.6 billion, a price that was considered a pleasant surprise. Now she's running GE Enterprise Solutions, a new business focused on boosting productivity through technology and automation solutions. GE estimates that it will be an $11.6 billion operation. Begley will report directly to CEO Jeff Immelt.
