The document discusses four key skills that are missing from many project managers' skillsets: selling, negotiation, understanding goals and direction, and leadership. It provides information on each skill, including definitions and techniques. For selling, it covers the SPIN questioning process. For negotiation, it discusses preparation and exploration. For goals, it explains how strategy and initiatives define projects. And for leadership, it distinguishes between leading leaders versus contributors on a project. The overall document aims to educate project managers on these important soft skills.
