Purpose: The article presents an application of FMEA method in a process of chimney system production. The analysis allowed to decrease a potential defects and their effects in the analysed process. Design/methodology/approach: The technical analysis of the process of chimney system production indicated many defects in the product. Based on the FMEA results (value of RPN – Risk Priority Number) corrective and preventive actions were proposed. These actions decrease RPN level by half. Findings: In this paper characteristics of the chimney system and technical analysis of its production process were presented. Failure mode and effects analysis for selected operations of the production process was performed. Practical implications: In the analysed process are possible the nonconformities above the appointed RPN level, because they are dependent on applied technology and machinery. Increase of a quantity of control points and training employees caused a reduction of manufacturing costs, improvement of the product quality and creation of the possibility of effective quality control. Originality/value: FMEA analysis is an effective tool for identification, determination of a risk level, planning and implementation of corrective and preventive actions to decrease a quantity of defects in the final product. Periodic application of this method enables the continuous improvement of the processes and products in enterprises.
