I copy this from the slack channel
I use it for interviews a lot. Mainly as an ice breaker:
Before we begin the actual interview we play a round of Testsphere. Important here is to use a subset of cards to which the applicant might be able to say something (use CV for that). If the applicant thinks he cannot say something you add a lot of stress in an already stressful situation. Played right you create a much more conversational atmosphere, because everyone is on the same level now.
I expand on the usage by asking questions into ; after the story and allow the same to the applicant. My dream is to at one point make a complete interview just one big round of Testsphere with detailed questioning in each others story.
2.) During Testing
Also I use TestSphere if I get stuck during Test session for new inspiration. Sometimes I even plan my sessions out like that. Here is a picture of Cards I choose to guide my testing for a UI feature in our mobile app.
3.) Starting conversations
Like Christina I have it on my desk ans people ask about it. I also use it at meetups or round tables and just start playing, usually I tell the first story but from there people keep up and it is a very good way to start talking about specific topics (the stories) to generic ones (the concept on the card).
