Our world has evolved through innovation from the Industrial Revolution of the 1740s to the information age, and it is now entering the Fourth Industrial Revolution, driven by technology. Technology is driving a paradigm shift in the way digital solutions deliver a connected world, changing the way we live, communicate and provide solutions. It can have a powerful impact on how we tackle some of the world’s most pressing problems. In this radio show, Caroline Dowling, President of Communications Infrastructure & Enterprise Computing at Flex, will join Women in Comms Director Sarah Thomas to discuss the impact technology has on society and how it can be a game-changer across the globe; improving lives and creating a smarter world. Dowling, a Cork, Ireland, native and graduate of Harvard Business School's Advanced Management Program, will also discuss her experience managing an international team focused on innovation in an age of high-speed change.
