Government and private health agencies are being compelled by internal and external forces to integrate their electronic records and resources. Many medical systems consist of isolated, disparate implementations that are now being required to interoperate with other systems. This study reviewed the literature on healthcare and other large systems of systems (SOS) implementations and frameworks to determine common problem themes. Reports on large government systems revealed that planning frameworks had difficulty accounting for unexpected aspects of system behavior when a systems' whole exceeds the sum of its parts. System Dynamics modeling, first developed at MIT, was examined as a possible answer to comprehending large system behaviors without being overcome by implementation details.
