Roadmap


Quantitative analysis is being applied to CASoS primarily through incremental adjustments to current theory and analysis tools. The sheer complexity of CASoS, the subtlety of their adaptive behaviors, the difficulty of running experiments and the problems of integrating the different analytic frameworks and representations required to understand their component systems underscores the need for new theory, methods and practice. However, this larger field is currently poorly understood, far from integrated and lacks consistent foundational theory or approaches for either discovery or application.

Sandia leadership commissioned a Roadmap for pursuing CASoS Engineering (2007-2008) in which we first articulated a set of Defining Examples for a broad spectrum of CASoS to verify our assumption of underlying commonalities. A presentation developed as an invitation to the roadmap illustrates the CASoS engineering approach as implemented in real time on Pandemic Influenza to demonstrate what a CASoS is, how problems can be defined and solved within CASoS and the use of CASoS principles to actualize solutions.

We identified theoretical principles and an iterative adaptive structure for actualizing solutions influencing CASoS. This envisioned structure is composed of a set of five continuously expanding critical components:

The goals for this roadmap were to:

Defining scientific terms for an emerging field is surprisingly difficult. We developd our shared understanding through the use of ordinary language, metaphor, analogy and social interaction, but the formal definitions that are our goal must be expressed in terms that transcend cultural idioms and individual ambiguities.

Our approach to defining CASoS was to compile a small set of examples we agreed were CASoS and then draw a working definition out of their common qualities. This definition went beyond essential qualities to encompass the activities necessary to define CASoS as a field of scientific or engineering study, the actualization of engineered solutions within CASoS (getting them used) and the requirements (theories, technologies, tools and approaches) for enabling the influence of CASoS. These Defining Examples cover many of the nation's (and humanity's) most important current and future concerns.

The Roadmap also identifies theoretical principles and iterative adaptive structure we envision for actualizing solutions influencing CASoS. In response to the Roadmap, we have created the Phoenix Pilot to begin building the discipline of CASoS Engineering within Sandia.
