Conclusions
The great diversity of marketing definitions and characterizations is not favorable to management theory and practice in the 21st century, being generally the consequence of a non-systemic approach and analysis of organization/ company functions. The methodology of systemic approach and analysis has been applied at the level of the organization/ company functions, with deepening the complex mixed “marketing” function, while going through all classical stages: defining the problem; identifying related systems; developing and analyzing new alternative solutions to solve the problem; recommendations for applying optimal/ suboptimal solution. The systemic approach and the original matrix model "7 Environments - 7 Resources/ Products", with 7 external environment categories and 7 categories of organization/ company resources/ products, allowed relevant contribution: x a better systemic definition of the 11 organization/ company functions, x a more rigorous definition and characterization of holistic marketing and its components, x an extended definition of the "9P" holistic marketing mix, x a basic description of the stages of lasting/ sustainable competitiveness cycle “1+10” of holistic marketing. The practical application of the obtained results facilitates the orientation of organizations/ companies towards lasting/ sustainable progress. Deepening the content of self-contained cycles of lasting/ sustainable competitiveness of organizations/ companies and their subsystems, included marketing, is an objective of future research.
