Developed by Marc Stickdorn and Jakob Schneider the Customer Journey Canvas is a nice tool described and used in their book on Service Design Thinking.
The idea behind the canvas is to supports the audit of existing services, covering not just the period of time associated when customers face the service, but also the time before (pre-service) and after (post-service) of the customer journey. Since I found it useful I’ve took sometime to translate it to portuguese, so if you’re interested you can find it download it here, or from the service design thinking website.
Put your service to the test and ENJOY! 😉
