Purpose: The main aim of the paper is to identify, evaluate and improve the factors that are responsible for the reliable operation of the guttering system using the Failure Mode and Effects Analysis (FMEA) methodology. Design/methodology/approach: To achieve the planned goal, the FMEA method was used. This is one of the suitable techniques of reliability modelling used to investigate the failure behaviour of a products and processes. The article presents the use of design FMEA on the example of a guttering system that is produced in one of the companies in the Podkarpackie province. In order to do this, potential defects and their effects have been identified. Later, the control methods used in the company were specified. The frequency of potential defects was then estimated, as well as their significance and possibility of detection. Findings: The design FMEA method allowed the authors to reveal defects, including critical defects, which may significantly affect the construction of a guttering system. The defects and their root causes were identified, and a proposal for corrective and preventive actions was suggested. Originality/value: An original solution of a guttering system that is currently in production in the Podkarpackie province was tested. This analysis should contribute to improving the quality of products manufactured here.

W artykule zaprezentowano wpływ parametrów nagniatania hydrostatycznego na wybrane parametry topografii powierzchni. Badania wykazały, że w wyniku zastosowania nagniatania hydrostatycznego uzyskano znaczącą redukcję parametrów wysokościowych powierzchni po procesie frezowania.

The article presents the influence of hydrostatic ball burnishing parameters on selected surface topography parameters. Studies have shown that as a result of the use of hydrostatic ball burnishing, a significant reduction in surface height parameters after the milling process was obtained.
