CJML is a visual modeling language designed to help you learn, map, and explore customer journeys in a structured and intuitive way.

Although customer journey is the industry-standard term, CJML goes beyond just focusing on the customer. It takes the perspective of the human in any journeys, not only when the “human” is a customer. In CJML, the “customer” may also be a patient, user, employee, or any other role — reflecting the broader context of human experiences across different systems and services.

To dive deeper into CJML you can navigate to other sections below or take a look at the “Documents” section where you’ll find PowerPoint presentations that give a solid introduction to how CJML works.
