This document presents the lessons that have been learned during the development and operation of the Synthetic Theater of War Architecture STOW-A System. This product evolved over a period of more than four years, spanning both the Advanced Distributed Simulation Technology ADST 1 and ADST 2 contracts. In 1994, the Synthetic Theater of War Europe STOW-E demonstration provided the first step towards integrating virtual, constructive, and live exercise components. The system that resulted from the rapid modification of existing simulations was not designed for the set of problems inherent with exchanging data between dissimilar systems that used different protocols and computed different representations of units and basic loads, different terrain, etc. While the basic concept was proven, the system was not stable and had limited functionality. The first major upgrade to the initial STOW-A system was accomplished to support the Prairie Warrior 93 exercise. The limited virtual simulation and the interface of STOW-B were replaced, and the resulting system proved to be more reliable and extensible, but again the quick turnaround defined by the exercise date limited the ability to design or test the software. Significant improvements were achieved in the correlation of behavior, terrain, and fidelity between the constructive and virtual worlds. User comments and developers design concepts were collected, correlated, prioritized, and implemented in time for STOWEX 96. Over the next two years, there was sufficient time between exercises to discuss user needs, add functionality, and strengthen stability within the context of improving software design and implementing a controlled test approach.
