Book excerpt: What makes a great leader? It's a question that has been tackled by thousands. In fact, there are literally tens of thousands of leadership studies, theories, frameworks, models, and recommended best practices. But where are the clear, simple answers we need for our daily work lives? Are there any? Dave Ulrich, Norm Smallwood, and Kate Sweetman set out to answer these questions—to crack the code of leadership. Drawing on decades of research experience, the authors conducted extensive interviews with a variety of respected CEOs, academics, experienced executives, and seasoned consultants—and heard the same five essentials repeated again and again. These five rules became The Leadership Code. In The Leadership Code, the authors break down great leadership into day-to-day actions, so that you know what to do Monday morning. Crack the leadership code—and take your leadership to the next level.
