Among hypotheses supporters exists a belief that the hypothesis creates the research process framework, implying that the other elements of the research are not as important for reaching the goal. This opinion directly promotes a methodology built solely on a system of hypotheses with its variables and indicators as a sufficient road to project realization. Correctly constructing a hypothesis and its system of variables and indicators is never a trivial process. The conceptual definition of the hypothesis, its functionality, classification and structure requires additional research work and in most cases can be considered a separate research project. In this paper, special importance is assigned to the hypothesis and its conceptual definition; how it originates and is discovered along with its functionality, classification and structure and the derivation of the hypothesis and its variables and indicators with all their necessary scientific attributes.
