AI needs to be central to any organization's strategy today, but many are still not implementing the technology in the most effective ways. In this four-part special series, we'll share conversations from the recent HBR Strategy Summit to help you get ahead. In this episode, HBR editor in chief Amy Bernstein speaks with Nigel Vaz, CEO of Publicis Sapient, a digital transformation company. Vaz explains that many enterprise-wide AI initiatives fail because incentives, talent strategies and a sense of trust aren't considered thoroughly enough. He shares lessons from his front row seat to AI transformations in the last few years, and how he thinks you can create real operational value at scale.
