To create a sustainable digital culture, eBusiness leaders must embed digital skills, knowledge, processes, and technologies within their firms and must reinforce and adapt the culture as the world around them continues to evolve. This means embracing agility and learning to be truly cross-functional. This report examines some of the strategies that digital business executives employ to digitize business strategy from within their area of accountability and the ways they are making customer insight and agility core to their continuous improvement. This is an update of a previously published report; Forrester reviews and updates it periodically for continued relevance and accuracy. We revised this edition to factor in new ideas and data.
