Decisions’ modelling often relies on numbers and symbols and we might say that very often decision-makers interpret numbers in order to obtain symbols that are qualitative factors. Interpreting qualitative factors is an aspect that has little to do with rational approach of decision-making and in this way there are no static decision-models. We sustain in this article that defining decision steps and information needed in making decisions belongs to the decision-maker and in this respect the control on data sets must be specified by the decision-maker at the decisional place. In this scope, the aim of this research is to identify the way of making business decisions. The results discuss the optimal way of using different technologies.
