The success of the metallurgical industry depends on personality of its managers, their personal ability, and charisma. A manager is someone who makes important decisions concerning the company and its operations, who determines the purposes and prepares plans for the future. Production process of metallurgical products, especially of ribbed bars, is quite tough, it is usually conducted in a four-shift system, the results are impossible to be corrected. For high quality products, the appropriate production technology for the manufacture of these products should be used. Therefore the manager should properly organize the rolling process, predict possible production problems and motivate in good way his employees. Poorly organized work, lack of coordination in procurement of materials, incorrectly selection of materials, the reluctance of employees have a very big impact on the final quality of the ribbed bars and later can cause that the building reinforced with them does not meet the relevant requirements.
