The essence of change

Behavior does not arise in a vacuum. It is always the result of an interaction between the person and the environment. This simple yet powerful insight is summarized by Leenman in the Change Formula: Behavior = Person × Interaction x Environment. Those who only work on the person – through training, coaching, or feedback – and ignore the environment, achieve at most half. And those who adjust the environment without understanding the person repeatedly encounter resistance.

Real change does not start with your plan, but with the other.

About the book

Change from the Other takes the reader to the origin of behavior and offers the Change Frame as a practical framework that connects classical insights with modern behavioral science. No abstract theory, but concrete tools, recognizable examples, and inspiring cases that are directly applicable in practice.

The book helps to look beyond superficial tips and truly understand what moves people. For anyone who has ever heard: 'But we've been doing it this way for years...'

Change Frame

The book offers a unique combination of classical and modern theories, translated into directly applicable interventions. The Change Frame is a clear visual model that makes complex behavioral change manageable, and it is filled with cases, tools, and smart tips that help you understand behavior and stimulate new behavior.

Who is this book for?

For leaders, managers, and advisors who do not want to impose change, but want to make it land. For anyone who understands that sustainable behavioral change does not start with a step-by-step plan, but with people.
