Fidelity is an important issue for good design so once the decisions are made about the nature of the Problem (the story, setting and stakeholders) the focus shifts to design of the details that add shape and dimension to learners’ enactment of a role play. These are identified as the Roles and Rules in the Design Space framework (Figure 4.1 in the previous chapter). Design considerations under Rules include:

• time in all its dimensions; • rules of participation; • modes of communication among participants; • where and how participants meet – virtually and/or face to face.
