Bill Sherman’s Impact Equation for Thought Leadership

Source: Bill Sherman’s Impact Equation for Thought Leadership

Bill Sherman leads a members-only Expert Session for The Upside, Erin Halper’s community of independent consultants, advisors and coaches. He defines thought leadership as taking ideas to scale and creating impact, often without positional authority; argues that ideas cannot speak for themselves and that you put value into the conversation before you extract it; then walks the Impact Equation (idea simplicity, audience relevance, velocity, audience share), multiplied, so a zero anywhere sinks the rest.
