This document summarizes the key ideas from the book "The 80 Minute MBA" by Richard Reeves and John Knell. The book argues that a new type of leadership and business is needed in response to the financial crisis, recession, and global warming. It focuses on five main areas: sustainability, leadership, culture, cash, and conversation. Sustainability involves considering climate change, ethics, and environmental impacts. Leadership requires knowing direction, understanding people and teams, and focusing on execution over strategy. Culture depends on engaged employees who contribute and make improvements. Cash relies on accounting fundamentals. Conversation means moving from one-way marketing to two-way engagement through social media and customer interactions.
