With a higher emphasis on human factors in the perceptions of modern and postmodern management in enterprises, individuals have now assumed the position of target and ceased to be means. Hence, enterprises need to renovate their corporate structures in such a way that they would give up old and rigid bureaucratic perceptions in order to adapt to social, economic and political changes, fulfil the requirements for a coherent structure in the framework of the conception of humanity, and satisfy employees special needs and interests. The Japanese Management style, i.e. Theory Z, which is believed to contribute to the management philosophy that would result in the desired change for the enterprises, constitutes the aim of the study. Therefore, the study mainly examines Type Z organisations, along with referring to Type A organisations which are employed in the USA. In addition, the study compares the cultural structures of Type A and Type Z. The study is conceptual and employs secondary data. In the conclusion part, the study provides findings and suggestions for the applicability of Theory Z in enterprises in order to create a sustainable organisational climate.
