<p>This research focuses on the application of existing assessment tools that may be  applicable to Marine Air Ground Task Force (MAGTF) Command, Control,  Communications and Computers (C4) System of Systems (SoS) performance assessment  efforts. An analysis of the Marine Corps Tactical Systems Support Activity's  (MCTSSA's) C4 SoS assessment approach provides a means for defining a MAGTF C4  SoS and for illustrating how that SoS is represented in the assessment environment. This  provides the framework and context for follow-on examination of SoS performance  metrics. The challenges with defining specific performance metrics and examination of  past assessment events using those metrics provide the basis for discussion of alternative  approaches and application of assessment tools specifically tailored for SoS assessment  efforts. Three specific tools, i-Score, Interoperability Quotient (IQ), and Dynamic  Software Architecture Visualization and Evaluation (DynSAVE), are examined. The  results indicate i-Score and DynSAVE offer the greatest potential applicability to the  MAGTF SoS assessment effort. In a culminating discussion, applying a multicriteria  identification process to obtain a mathematical model that correlates an interoperability  measure with measurable SoS performance criteria is proposed as a means of extending  the i-Score model for greater applicability to SoS assessment and performance  improvement efforts.
