One fascinating aspect of the public health field relates to the dynamic complexity between the systems that link social determinants of population health and the institutional organizations that determine the collective response to threats to community health. Since the late 1980s, a number of national practice organizations have sought to describe the institutional systems (the “public health system”) and others have focused on the many factors that interact to impact population health. One particular area of emphasis described as a critical skill area for leaders in public health practice has been an understanding of “systems thinking.”
A common point of entry for public health workers into this subject area (usually in the form of a leadership institute or other continuing education program) is Peter Senge’s, “The Fifth Discipline.” First published in 1996, this book describes the characteristics of “learning organizations,” and includes systems thinking as one skill leaders need to foster learning organizations. While learning organizations translate tacit knowledge into higher levels of performance or competitive advantage, the role of systems thinking (one of the five critical disciplines) in public health relates to the ability to recognize the interconnectedness of system agents, as well as the multiple layers that represent linked systems (sub systems, nested systems). But more specifically to the experience of public health practice, an understanding of systems provides insight into the relationship between biological, behavior, economic and institutional systems that interact, and provide an understanding why some groups are more vulnerable to violence, economic distress or poor health.
The Association of Schools of Public Health, the Centers for Disease Control and Prevention, and the National Leadership Development Network have described systems thinking as a basic leadership competency. But what does “systems thinking” mean…really? In order to begin to understand the systems sciences as academic disciplines, one place to begin is with a conceptual framework contained in a recent publication of the National Cancer Institute, “Greater Than the Sum: Systems Thinking in Tobacco Control.” While the practical illustrations were specific to tobacco control, this work contains a very useful model to understand four disciplines that fall under the rubric of systems sciences.
These four areas each represent disciplines in themselves. Perhaps more important is the understanding of how the academic disciplines relate to each other. These include:
(1) Systems Organizing
(2) Systems Dynamics
(3) Network Analysis
(4) Knowledge Management
Taken together, these four categories encompass the various fields that comprise systems sciences. Each of these in turn are applied differently to specific discipline areas. The National Institutes of Health, Office of Behavioral Health and Social Sciences Research is coordinating an interdisciplinary approach to building the systems sciences within social science research.

My own interest relates to public health systems research, and how organizations are linked together as a network; how variety in network structure across public health systems impacts the ability of our institutions to assure that the public health essential services are adequately being addressed; and how institutional systems incorporate learning and knowledge into organizational practice.
