Proceedings of the 1996 Command and Control Research and Technology Symposium: Command and Control in the Information AgeCurrent research involving adaptive archi tectures for Joint Command and Control (C2) seeks to examine the interactions between task (or mission) structure, and the way in which the organization charged with the mission is itself structured. In order to examine these interactions empirically, a flexible research paradigm is required with which to conduct controlled experiments in a laboratory environment. The 3rd-generation Distributed Dynamic Decision.making (DDD-111) paradigm was designed to meet this need by treating an air, sea and ground environment, a variety of task classes, and controllable platforms with subplatforms, sensors and weapons (resources). DDD-111 is implemented as a multi-player, real-time simulation running in a UNIX environment. The design of the DDD-111 focuses on the dynamic/execution phase of the mission and allows for manipulation of key structural variables in task and organizational dimen- sions. The DDD-111 has the ability to con- strain and/or to manipulate organizational structures such as authority, information, communication, resource ownership, task assignment, etc. This paper describes the new DDD-111 paradigm, its extensions beyond the DDD-11, the dimensions of task and organization structure considered, and how they are operationalized
