Opinion-based product design and development decisions are woefully ineffective.

“Design for Impact” gives you the science-backed tools you need to move beyond opinion and drive growth through experimentation. Packed with practical A/B testing advice and some hilariously instructive anecdotes, “Design for Impact” guides you through the entire Conversion Design process.

The Conversion Design process combines design, science, and business. Design by way of human-centered problem solving. Science by way of the scientific method. And business by way of value creation and transfer to stakeholders within the eco-system.

Unlike other design processes, which are based on linear thinking, Conversion Design is based on systems thinking. Systems thinking, is a practice and set of tools that helps you understand and capture things in a dynamic and interconnected way. With it, you can represent and understand the world around you more accurately to make optimal decisions in the face of complexity. 

Systems Thinking

Linear thinking vs. systems thinking.
Linear thinking has clear, cause/effect relationships. Systems thinking captures complex relationships between things.


Conversion Design works much like a machine. Teams work together and lean on each other’s strengths at different points in the Conversion Design process by representing a wide range of disciplines. Everyone plays an important role to get through each step.
