Lean management has become a much-researched topic in operations management. Beyond

its technical aspects, nowadays the analysis of soft factors (corporate culture, organization,

management, human resource management, knowledge transfer practices) have come to the

fore. However, there are few sources available to the lean organization to find out what organizational

changes are taking place alongside the lean application, and what organizational

structures are being developed. In our study first we deal with the literature-based concepts

of lean organizational structure and with the international examples, and then through five

Hungarian corporate solutions and with help of the literature of organizational theories we

synthesize the lean organizational forms.
