Viable systems approach

The viable systems approach (VSA) is a systems theory in which the observed entities and their environment are interpreted through a systemic viewpoint, starting with the analysis of fundamental elements and finally considering more complex related systems (von Bertalanffy, 1968). The assumption is that each entity/system is related to other systems, placed at higher level of observation, called supra-systems, whose traits can be detected in their own subsystems (principle of system hierarchy).

The fundamental unit of analysis is a system made up of many parts or structures (Parsons, 1971). In this sense, every entity (a firm, or simply an individual, a consumer, or a community) as a system can be considered a micro-environment, made up of a group of interlinked sub-components which aim towards a common goal (this is the condition, for the aggregate, to be qualified as a system).

The viable system model was first proposed by Anthony Stafford Beer. In general terms, a viable system is finalized toward its vitality throughout viable behavior based upon consonant and resonant relationships (Barile, 2000; Golinelli, 2000, 2005, 2010; Barile, 2008, 2009).

Systems thinking contributed in a significant manner to the creation of a new conception of phenomenological reality, as a synthesis of philosophical, sociological, mathematical, physical and biological approaches, influencing culture and its prevalent values founded on the axiomatic corpus of Cartesian thought, has set off a paradigm revolution, moving on from a reductionist-mechanistic approach to reality, and modifying the traditional investigation model. Having rapidly spread to all areas of study, the systems approach has become the result of reflection, theoretical contribution, and formalisation, creating an epistemological approach to research and to the study of a complex reality.

The origins of systems theory go back to the 1950s when a group of scholars from various scientific and social fields (von Bertalanffy in 1956, and others) developed an interdisciplinary theory based on the concept of systems. Their systems viewpoint rejected the idea that certain phenomena could be fully understood exclusively through an analytical approach, especially when the investigated subject consisted of complex phenomenon characterized by significant interaction among its components, as with the firm. In such a case, full understanding could be achieved through a global vision of the subject in question—a systemic vision—by applying a research method of this organized complexity.
