Even though, from a theoretical standpoint, professional management (considered authentic management) is a truism, the economic practice often proves the opposite. We need to admit that, in recent years, we have witnessed an alarming increase in the number of conjectural managers, of conjectural leaders, a phenomenon with negative effects on the economic, financial and managerial performance of the organizations they run, whether they operate in the public or the private sector. The negative effects are certainly not limited to the respective organizations, but propagate at society level. An authentic manager is a person who has managerial competences both in the domain they manage, proven by means of having graduated from specialized educational programs of certain higher education institutions (certified by means of graduation diplomas in compliance with the law, which warrants that their owners acquired the respective program’s general and specialized competences), and, also, by means of the results of their exerting managerial prerogatives in actual practice (managerial performance indicators and implicitly the economic, financial and managerial performance indicators of the organization/management structure they run, the supporting documentation mainly being the management agreement, the respective manager’s institutional assessments, the management reports, the audit reports and the organization’s financial-accounting documents during the management term/agreement). The objective of the research is to create a tool which makes it possible to quantify managerial performance and to design a new situational management based on correlating result indicators with organizational and managerial competence.
