Legendary venture capitalist John Doerr's revolutionary approach to goal-setting, which has catapulted tech giants like Google and is spreading from Silicon Valley to the rest of corporate America and leading nonprofits. Objectives and key results (OKRs) are a goal-setting process to help organizations, teams, and individuals attain excellence. Objectives define what goals matter most; key results are metrics that show how those top-priorities will be achieved within a set timeframe. In contrast to traditional top-down systems, individuals and teams design their own OKRs to ladder up to the company's core objectives. Since everyone has a clear stake in the collective mission, all hands work together to execute at the highest level. This two-way dynamic sparks engagement, autonomy, and innovation. Legendary Kleiner Perkins venture capitalist John Doerr--an early investor in Google, Amazon, and Twitter--brought the game-changing OKR approach to Google in 1999, when the company had fewer than 40 employees. He taught Larry Page and Sergey Brin how OKRs worked, as Intel's legendary Andy Grove had once taught Doerr. Grasping the method's power and potential, the Google founders adopted it as a framework to discipline their thinking and spur growth. After 70 consecutive quarters of OKR goal-setting, Google has more than 55,000 employees and the largest market cap in the world. Meanwhile, Doerr and former Google employees have disseminated OKRs across Silicon Valley and beyond. The results are clear: greater productivity and workplace satisfaction; sharpened, more coherent cultures; and continual improvement as managers evolve into leaders, mentors, and coaches.The book explores the OKR "superpowers" that strengthen an organization's "goal muscle." Using a broad range of case studies, from Google and Intel to Bono's ONE campaign and the Gates Foundation, the book demonstrates the proven benefits of OKRs-- focus, agility, and explosive growth. It can help every organization, of any size or sector, capture the same magic.
