Organizations increase their cooperations more and more because of the globalization of markets and because of in- creasing complexity of products, be they physical or non- physical (services). However, to fully capitalize on the pos- sibilities for cooperation, automatic support is required that enables rapid decision making in selecting (or changing) which organizations to cooperate with, as well as support for setting up the infrastructure to enact the agreed upon co- operation. Cooperating organizations together form a vir- tual enterprise.
