Part AAre organizational behavioral theories relevant in today's business world? Organizational theory is the sociological study of systematic social organizations, for example businesses and bureaucracies, also focusing on the relationship they have to the environment in which they function. Over the years, organizations have adopted these theories to shape and dictate how they manage and operate. No single theory is conclusive for all organizations as each organization is different and has different needs in which to operate. This article aims to analyze current organizations and the relevance of organizational behavioral theories in the modern business environment. It attempts to outline the main theories, how they are used in practice, how successful they are in practice and above all to provide an overview of their efficiency over the years and whether or not this has decreased over time. The certainty of the relevance of the first theory is questionable. Some may say that they are obsolete and cannot relate to modern organizations and social changes, others may say that they are fundamentally still valid and while society changes, the human psyche is still the same, while some are undecided and say that some are relevant. and some don't. This text hopes to demonstrate that these theories are still relevant today. There are many early attempts to theorize organizational behavior, these are often coined “classical organization theories”. The most famous are the socialist theories of Karl Marx (1848 - 1894), the bureaucratic theory approach of Max Weber (1922) and the theory of human relations of Elton Mayo (1933). Some may speculate that they are no longer relevant, but there are examples of how they are put into practice today. Elto...... middle of paper...... in his 360 BC publication "The Republic" addresses the topic of leadership. In it he highlighted the importance of specialization and discussed a primitive form of incentive-based structures in the hypothesis of how to convince people to embody the goal of the fair city (Jowlett. B, 2008).
