Welch was both an active manager and a master corporate ambassador. He was legendarily peripatetic, traveling constantly to visit GE's far-flung operations, tirelessly grading managers and shuffling them between business units, and developing companywide strategic initiatives with exotic-sounding names like Six Sigma and TQM. Welch had a lively, pugnacious personality and enjoyed his interactions with Wall Street and the business press. He was very comfortable in the limelight, and during his tenure at GE, he frequently appeared on the cover of Fortune magazine.
