Business communication is increasingly becoming social. Social business software is the next hot trend in business technology. As younger generations enter the workforce, they expect the same social collaboration tools they use personally to also be used at work. Over the next 5 years, the majority of companies will have a corporate social network to facilitate internal communication and collaboration among employees in a way that is more social and engaging. This transition will be led by top management and department leaders rather than IT, and will require new roles focused on digital strategy, community management, and user experience.
