The Impact Equation

Thought leadership is the work of creating impact through ideas. Impact is yours to define.

  • For yourself: recognition, income, and legacy
  • For your clients: their revenue, reputation, and growth
  • For your learners: their clarity, capability, and trajectory

The Impact Equation:

Impact = idea simplicity × audience relevance × velocity × audience share.

These factors multiply; they don’t add. When any one approaches zero, impact vanishes. The equation tells you what’s working and where to apply more effort.

The Impact Equation: idea simplicity, audience relevance, velocity, and audience share

Idea Simplicity

Simple outperforms complex.

How to Test It

Ask someone who heard your core idea just once to repeat it in their own words. Note any critical differences.

Audience Relevance

Ideas must earn four things from an audience: time, effort, resources, and reputation.

How to Test It

Watch what key members of your target audience say and do. See the Comfortable Corners of Thought Leadership if your efforts aren’t earning their attention.

Velocity

Velocity measures the rate your core ideas travel. It’s powered by two sources: “you” and “not you.”

  • Personal velocity is finite. You can only do so much in a day.
  • System velocity scales, because effort can come from anywhere other than you: team members, fans, products, licensees, certified facilitators.

How to Test It

Tally the people, products, and partners producing velocity for your ideas in any given month. If you’re the only entry, your potential impact is capped by your effort. See the Three Business Models for Thought Leadership (Hobbyist, Practice Owner, Business Builder) if your velocity mix doesn’t match how you’re trying to practice.

Audience Share

The percentage of your target audience engaged with your core idea. Narrowing your audience raises your audience share. Serve them well.

How to Test It

Calculate a ratio: estimate the number of people in your target audience engaged with your ideas vs. the total size of your target audience. Are you reaching 1%, 0.01%, or 0.00001% of your target audience?

How to Use the Impact Equation

The Impact Equation provides directional guidance and helps you prioritize your efforts. If your audience share is near zero, sharpen your audience definition. If people see your ideas but can’t explain them, work on idea simplicity.

Fix the zero that’s preventing impact.
