all PTA projects are assessed on three axes : Human Context - Open Ended - Interaction. Both project and process are combined in a simplified diagram. These three concepts are taken from the method for a human based design process that is described below. It gives us a tool to evaluate and compare projects on their ability to provoke social relevance and a 'joie the vivre' for their users. The larger the triangle formed by the quotes on the three axes, the higher the impact on the human context.
