some years ago, one of my coworker used a visual card game to help define a, ideal customer Journey around an e-commerce site.
Based on a set of small visual item (like Customer, action like search or pay, etc..), used to build collaborativly a path and optimize it. It helped a lot our team and customer on defining the future product. Unfortunatly, i'm not in touch anymore with her, and i didn't keep any information on this card game method.
Edit : i'm aware of the plex card. What i've seen is a more "operational" set of cards.
Does anyone have seen similar methods and luckily have ressource to point me at?
Thanks, Antoine (and sorry for the approximative English)
