Influential business and management ideas have tremendous influence over us. Like it or not, they shape how organizations are run and how people around the world spend their days. And Harvard Business Review has introduced and spread many of these consequential ideas since its founding in 1922. HBR IdeaCast is taking this 100th anniversary to ask: how have these ideas changed our lives? And where are they taking us in the future? Each Thursday in October, the podcast feed will feature a bonus series: 4 Business Ideas That Changed the World. Each week, a different HBR editor talks to world-class scholars and experts on influential business and management ideas of HBR’s first 100 years: disruptive innovation, scientific management, shareholder value, and emotional intelligence. Listen to the conversations to better understand our work life, how far it’s come, and how far it still has to go.
