ABSTRACT
Complex adaptive systems are dynamically assembled
systems characterized by multiple competing
stakeholders, fluid requirements, emergent behavior, and
susceptibility to external pressures that can cause change
across the entire system. Net centric operations for the
US Department of Defense (DoD) can be considered a
complex adaptive system, representing a shift from
traditional system-based interactions toward informationbased
web service transactions requiring highly secure,
reliable, and dynamic "on-demand" capabilities. This net
centric environment must accommodate unpredictable
external factors that demand rapid response and
flexibility to change. This paper presents an approach to
modernizing toward global net centric operations for the
DoD. We discuss key principles of complex systems
engineering to consider, approaches to on-demand data
and IT infrastructure strategy based on web service and
semantic web technologies, as well as guidance and
initial observations on spiral development and
management using Communities of Interest combined
with a Developer's environment.
