The dynamic of informative varieties in the processes of decision making

Decision-making in top management is necessary, and continuously influences a given context. The process used by decision-makers is usually based on uncompleted data, and does not have a scientific basis. Decision-making studies, including recent works from the field of psychology, especially regarding the notion of subjectivity, use complicated and laborious procedures of calculation, where reliable and easily available data is necessary during this process. However, today it seems clear that organized working structures cannot make their decisions on sole calculation, for it is necessary to understand the nature of the elements, which become part of this process. So which factors bring to a right or wrong choice, and which knowledge-elements contribute to determine a safe solution? The Viable System Approach, VSA, (L'Approccio Sistemico Vitale), with the parameters of consonance and resonance, measures the appropriateness of a decision in a problem-solving context. This model bases its dynamics on the following concepts: system variation of information (V), categorical values (C) (strong beliefs) and patterns of synthesis (S). This paper, after a short introduction regarding basic VSA concepts, then concentrates on the concept of decision-making in complex contexts. The proposed model analyses the level of knowledge perceived in a knowledge-acquiring situation and allows us to identify possible paths of resonance.
