This document provides advice on how to influence others without direct authority. It recommends first listening to understand others' needs, wants, and definitions of success and failure. Norm-setting exercises can establish expectations for how groups will work together. Understanding different cultural maps and communication styles is also important. Speaking the language of the environment and finding ways to frame individual and group goals as shared ("make an US") can help build influence. Self-awareness of strengths, weaknesses, body language and how one is perceived by others also plays a role in wielding soft power over hard power.
