Depending on the goals and objectives of an exercise, an exercise can involve a narrow or wide range of potential participants. While broader inclusion would likely be more realistic, such inclusiveness needs to be weighed against the logistics of effectively managing a larger number of participants and the potential adverse effects of inclusion. For example, participants may be less comfortable discussing ideas, taking risks, or making mistakes, depending on who is in the room. Such constraints may impede the exercise process and undermine achievement of exercise objectives.
