For most T&D organizations, their big data are just data. At Grant Thornton, in the last 12 months alone, we gathered more than 750,000 evaluation question responses. Add that to our LMS, HR, and T&D financial data, and it is clear that we are not suffering from a lack of data. Our challenge, however, was to transform this big data into big insights and to do that, we needed both a strategy and a tactical plan. This case study shares the Grant Thornton journey as we transformed our measurement and along the way, recognized that it is “bigger than big data.”
