This session briefly traces the history, use, and concerns about ROI with the primary focus on the basics---how you do it. Using exercises, activities, job aids, and case studies, you'll learn about the types of data, the steps in the process, when to use ROI, how to save time with shortcuts, how to use the results, and how to minimize the fear of ROI. This session was recorded at the ATD 2019 International Conference & EXPO, May 19 - 22, 2019 in Washington D.C.
