Measure What Matters: How Google, Bono, and the Gates Foundation Rock the World with OKRs

Doerr's book is the popular introduction to OKRs — objectives and key results — the goal-setting system Andy Grove developed at Intel and Doerr carried to Google and from there to most of Silicon Valley. The case studies are the strongest part: Bono, the Gates Foundation, early Google, showing OKRs working in settings where the usual management vocabulary falls apart. The framework itself is deceptively simple; the book's real value is in the chapters that walk through how teams fail at it, which are more instructive than the success stories. For product direction it is worth reading even if your organisation uses a different system — the book's diagnostic on goal-setting is portable. Pair it with Grove's High Output Management (the source text) for the deeper version.
