The IPD model seeks to create a team approach where all parties enter into a single contract, and where the decision making, the risks and the profits are shared. Proponents of the model suggest that this approach should minimize, if not eliminate the adversarial dynamic that can develop when each party pursues its own interests; and hopefully incentivize more cooperative and collaborative relationships.
