Want great employees? Grow them yourself. This was the philosophy that prompted global science and technology corporation Siemens to develop two new scholarship programs for advanced placement high school students excelling in science and math. The idea: Siemens would cough up $1 million to help bankroll college tuitions for top students, and later offer internships to the most promising grads. The catch was that organizers had less than nine months to get the program up and running.
