Design goal and metaphor

To define our design goal we looked at our target group, the effect we want to achieve and the interaction vision we have. As target group we have people that want to have spontaneous catch-up meetings. We want to enable people to schedule an appointment with friends. We want this in a convenient and friendly way.

Our design goal is:
We want to enable people, that want to have spontaneously catch-up meetings, to schedule an appointment with friends in a convenient and friendly way.

To understand our design goal better we made a metaphor for the experience of using our solution.
The experience should be like making popcorn.
