Method Supporting Improving Products in Terms of Qualitative-Environmental

Abstract

Abstract. Problems with product quality during negative climate changes make the continuous improvement process difficult. The search for approaches consists of methodical and possible detailed analysis areas of these types of problem types. Therefore, the objective of the article was to develop a method to analyze problems with the quality of products considering the impact on the natural environment. The method was developed by a coherent combination of selected techniques, i.e.: brainstorming (BM), Ishikawa diagram, 5M rule, multiple voting, seven-point Likert scale, and the IPA method. A method was carried out for mechanical seal of the 410 alloy, on which a porosity cluster was detected. The originality of the study is that the proposed method supports a consistent methodical analysis of any problem with the quality of products and verifies these problems in view of their impact on the natural environment. Simultaneously, the result obtained from the method determines the main causes of the problem, from which to begin improving the quality of the product considering the impact on the natural environment. This method can be applied to any product and the incompatibilities detected on them. Therefore, the method can be used in service-production enterprises to improve products in terms of qualitative-environmental.
