How do companies stay competitive in a cloud-based world? According to AT&T, a company that now competes with industry giants like Verizon, Amazon, and Google, training is the secret sauce. In a recent New York Times article, AT&T CEO Randall Stephenson states the only way AT&T will stay relevant is to retrain its entire workforce. Most AT&T employees, including Stephenson's brother, have been with the company for more than a decade and are used to doing business the old way. How does Stephenson plan to retrain his workforce? In addition to partnering with Georgia Tech, he's taking a blended approach of online and live courses. Will AT&T's intense training make it a heavyweight contender? Only time will tell.
