BlackBerry's Chief Executive John Chen said Sims' extensive experience in transforming businesses and redefining brands will be a tremendous asset to BlackBerry as the company seeks to turn around its fortunes.
Chen, who recently took the reins at BlackBerry, is keen to rebuild the company as more of a niche player focused on the so-called enterprise market of large government and corporate clients.
The company's new BlackBerry Enterprise Service 10 platform allows such clients to now manage BlackBerry, Android and iOS-based devices on their internal networks.
