John Doerr, the chairman of the venture capital firm Kleiner Perkins Caufield & Byers, talks with Recode's Kara Swisher and Teddy Schleifer about his new book, "Measure What Matters: How Google, Bono, and the Gates Foundation Rock the World with OKRs." Doerr credits two mentors, Andy Grove and Bill Campbell, with turning him on to that leadership strategy, which is short for Objectives and Key Results — or, in other words, communicating what you want to accomplish and how. Setting clear objectives and making them transparent to your entire company can help tech leaders succeed, but CEOs who don't commit or who build a cult of personality around themselves can put their businesses in jeopardy. Doerr also talks about the state of diversity in Silicon Valley, what he learned from the Ellen Pao trial and whether tech companies are taking privacy more seriously in the aftermath of the Facebook-Cambridge Analytica scandal.
