Sony's CEO, Kazuo Hirai, talks to WSJ staff in April 2015, on ways in which it has changed as it adapts to the new competitive environment. He says the basic DNA remains the same with its focus on innovation. What has changed is the sense of urgency, accountability starting at the top, and the ability to adapt quickly to the competitive environment. Hirai describes his personal life at home alone in his condo, with his family in California. He spends the quiet time on the weekends in the condo thinking over decisions to be made, testing the logic, and adds that he rarely changes once he has made up his mind.
