The Carlyle Group is partnering with Patrick Doyle, the former CEO of Domino's Pizza known for turning around its business by overhauling its recipe and implementing new technology like online ordering. Doyle, 56, is now a private-equity investor and will help Carlyle identify multibillion-dollar deals in the consumer and retail sectors. Doyle spoke with Business Insider about how companies could improve operations and said they would increasingly benefit from the use of voice technology.
