To this end, the approach makes use of teams of evaluators who present two opposing views (these teams are commonly referred to as adversaries and advocates). These two sides then agree on issues to address, collect data or evidence which forms a common database, and present their arguments. A neutral party is assigned to referee the hearing, and is expected to arrive at a fair verdict after consideration of all the evidence presented.[4]
There are many different models for adversary evaluations, including judicial, congressional hearing and debate models. However, models which subscribe to a legal-framework are most prominent in the literature.[5]
