In order to become more and more competitive, the nowadays firm could face many problems and constraints. These could be solved by implementing the Japanese management techniques, which were not only successfully verified in the origin country, but also their implementation in other contexts (European or American ones) proved to be the solution for the survival and development of the firms in the present turbulent economic environment. The author’s proposal is a software system (its professional version) which realizes the application, in a perfect logic of the KANBAN system, of the algorithm that synchronizes the final assembly line of an industrial firm, in order to permit the small-batch production. There are presented the principles of the Toyota system, the way of functioning of the KANBAN technique as a useful tool of the Just in Time system. The software elaborated on the base of these principles uses the ACCESS medium and was already applied to the bearings industrial plant from Birlad.
