With its primary focus on business results and return on investment, American Express once again takes center stage and pioneers the research on how to most effectively deliver best-in-class training for its global population of people leaders. While companies all over the globe are scrambling to offer their employees a variety of training media, there exists little, if any, research to support their ultimate investment decisions. American Express, a $64 billion, global organization with more than 65,000 employees in 45 countries, has compared and analyzed three delivery options for its leadership training program - online, instructor-led, and a blended approach, using the results to inform its training strategies and maximize return on investment (ROI).
