John Doerr

Grove built OKRs at Intel in the 1970s as 'iMBO' — his repair of Peter Drucker's Management by Objectives, adding a faster cadence, self-set measurable results, and a firewall between goals and performance reviews. Doerr absorbed the system in Grove's Intel classes, and as a Kleiner Perkins investor pitched it to Larry Page and Sergey Brin in 1999, when Google was 40 people in a converted house. Measure What Matters, two decades later, is Doerr's account of why it stuck — and his warning about every way companies deploy it wrong.

Doerr learned OKRs directly from their inventor — Andy Grove, who built the system at Intel as 'iMBO' and whose management classes Doerr attended as a young engineer. As the venture capitalist behind Kleiner Perkins' defining bets, he carried Grove's system to a 1999 startup called Google, where forty employees adopted it and never stopped; Measure What Matters later told that story and made OKRs the default operating cadence of ambitious organizations everywhere. Doerr's framing preserves what most implementations lose: objectives are inspiration, key results are proof, and grading them into compensation kills both.
