I'm not sure what "digital transformation" really means
I think a lot of companies go throught the "digital" motions, adding social, mobile, and big data projects or capabilites, for example, without really changing the way they do business. If it's a thin veneer of digitization, it's all for show. For me it gets down to the level of innovation, business transformation, new products, new services, and new business models that are created. It has to be meaningful, and that's hard to capture in a study.
