In this smart, practical, and research-based guide, Harvard Business School professor Frank Cespedes offers essential sales strategies for a world that never stops changing. The rise of e-commerce. Big data. AI. Given these trends (and many others), there's no doubt that sales is changing. But much of the current conventional wisdom is misleading and not supported by empirical data. If you as a manager fail to separate fact from hype, you will make decisions based on faulty assumptions and, in a competitive market, eventually fall behind those with a keener grasp of the current selling environment. In this no-nonsense book, sales expert and Harvard Business School professor Frank Cespedes provides sales managers and executives with the tools they need to separate the signal from the noise.
