These sketches are the backbone of a customer experience Waveline. A Waveline provides the client with a visual representation of the experiences felt by their customers over the lifetime of a product. The map provides a framework to make sense of the way customers learn and interact with the various touchpoints over time.
This is a design variation showing the overlap of users and the delta between their experiences.
These were the initial sketches for the Waveline template. How to show time, intensity, multiple personas over numerous touchpoints.
