Abstract

Every weapon system operates in context with one or more system of systems (SoS). It is the SoS that provides warfighting capability. Each system is managed independently by a program office with program-centric priorities. These systems must be interconnected and interoperable, so the program office must collaborate across the SoS. The SoS are always changing and evolving, triggered by variety of stimuli. Acquisition program offices can be characterized with a set of organizational behaviors that respond to the environment, are influenced by SoS architecture, and can be described by their fitness and contribution to SoS. Using Geert Hofstede's cultural dimensions, integrated with a modified version of the Bak-Sneppen biological evolutionary model, this research highlights which set of behaviors are significant in affecting the SoS fitness. Through the use of agent based modeling, it was determined that organizational behaviors of willingness and ability were significant factors to local fitness with correlation of 0.548 and 0.535 respectively. Using these factors, a regression model was built to predict the local fitness of the system. Additionally, global fitness was highly dependent on the influence from connected systems. Lastly, the SoS global fitness remained highly stable after a period of time throughout different modeling strategies.
