For two decades, companies have introduced new and potentially better tools to help employees collaborate, only to see tepid adoption. In the past several years, employees have begun to self-provision their own tools, like Dropbox and Skype. The cost of poor adoption is twofold: underutilized investment as well as unmet business objectives. This report details the skills and resources that application development and delivery (AD&D) professionals need to drive adoption and change management in collaboration initiatives. This is an update of a previously published report; Forrester reviews and updates it periodically for continued relevance and accuracy.
