Understanding Team Performance Measures: Applications of Petri Nets

Previous team decision-making research is reviewed and a Petri net representation of the replenishment-at-sea task is described. Three alternative Petri net representations of a team task are then presented. A functional representation which relies on a top-down decomposition of the task by function is a clear representation, but it lacks information about the task from the individual team member's perspective. A detailed individual representation is a top-down decomposition by team member, but it too has shortcomings. A third representation. called a parsimonious individual representation, is a top-down decomposition of the task within each team member. This representation retains the most attractive property of the previous two by maintaining the functional representation of the task, but it presents the task in terms of only critical behaviour from the perspective of each individual team member.
