Probably every organisation focuses on obtaining very significant market positions in their field of business. The production for customers is overriding for it. However, meeting this goal is preceded by its production. Now the preparation of production is sometimes on the edge of the interests of its staff, although it is now scientifically strengthened, e.g. in the field of maintenance or materials. The maintenance needs for operation of every device simple materials and spare parts. This article describes a pilot project of authors, carried out in the Czech Republic on a sample of selected organisations. The project deals with the control of materials and of spare parts inventory in organisations. It describes the current state of the problem and nonconformities occurring in this material field. Results of the survey are compared with findings from a brief literature research. The preparation of the device is a key part of material savings in terms of spare parts, but also from the perspective of a subsequent production. Therefore the article proposes a solution in the area of control of materials and of spare parts inventory for strengthening the competitiveness of these organisations.
