    Opis:
    Dynamically identifying key product changes is a challenge for enterprises. It is even more complicated if companies strive for the sustainable development of their activities. Therefore, the aim of the article was to develop a method to help predict the direction of product improvement, taking into account its quality level and environmental impact during the life cycle (LCA). The method was based on the design phase of LCA and the process of obtaining and processing customer expectations. Techniques supporting the developed method were: a questionnaire, a seven-point Likert scale, a standardised list of criteria for assessing the product life cycle, the WSM method, and a scale of relative states. The product analysis was carried out according to modified criteria states, which were evaluated according to: i) customer satisfaction (quality criteria), ii) environmental impact of LCA (environmental criteria), and iii) importance of quality and environmental criteria for customers. The originality of the method is to support the product improvement process to make it environmentally friendly within LCA and, at the same time, satisfactory to customers in terms of quality. The method will be used mainly by SMEs that want to initially predict the environmental impact of a product, including taking into account customer expectations.

    Opis:
    The analyses of the nonconformity of products are made in order to achieve the desired level of their quality. This is also the case in the analyzed enterprise located in south-eastern Poland. Due to production character in this enterprise to identify the incompatibilities of products the non-destructive tests are used. In the current approach to quality after identified the nonconformities the cause her arise were determined, it was noted in order to use by statistical analyzes. Unfortunately, no deeper qualitative analyzes were made which could specify the source of its creation. Therefore, it was considered that it is necessary to propose to use (near current actions according to nondestructive tests) the sequence of quality management instruments. In order to improve the quality control actions, the sequence of techniques which complement each other, i.e. non-destructive tests, Ishikawa diagram and 5Why method, was proposed. To demonstrate the effectiveness of the proposed sequence, the rear cover of the bearing turbine was selected as the subject of the analysis. The choice was conditioned by the unit character of production, which till now was discouraged a detailed analysis of sources of nonconformities. After analyzed the product with used the fluorescent method the nonconformities were identified on the rear cover of the bearing turbine, which was the porosity cluster. In order to identify the causes these nonconformities the Ishikawa diagram was drawn up. Next, the selected main causes (i.e. supplier of the product and nonconformities created during the production of the product) were analyzed the 5Why method in order to identify the source cause of the problem. In this case, it was the nonconformity material from the supplier. The proposed sequence, which uses the minimal resources let to show the wide range of information, which should be used to the improvement of quality. The presented the set of activities can be practised in each of the enterprises to analyze quality problems in order to identify the nonconformities and their causes.

    Opis:
    The analysis of the problem of the mechanical damage was made for a company manufacturing furniture and furniture fronts. From January to September the company identified 285 pieces of mechanically damaged products. The management of the company wanted to identify the source of the incompatibility; therefore, it was purposeful to analyse the problem of the mechanical damage using the sequence of the selected instruments of the quality management that enable this. Additionally, until now the company has not used the instruments of the quality managements to analyse the problems involving nonconformity, so it was important to show the company their practical use. The aim was to analyse the problem of the occurrence of the mechanical damage in fronts and furniture and to identify the root cause of the problem. Also to show the effective use of the sequence of the quality management instruments (i.e. 52WH method, Pareto-Lorenz diagram, Ishikawa diagram, 5Why method) to solve the problem of incompatibility. It was concluded that the root cause of the mechanical damage of fronts and furniture was the lack of management knowledge and awareness of the need to implement visualization principles in the company. The analysis and the proposed improvement actions may be practiced in other companies from both the production and service industries.

    Opis:
    Purpose: The effectiveness of the NDT tests is to identify the incompatibility of the products without their destruction, but NDT tests do not point out the root of incompatibility. The aim of the study was to identify the incompatibility in the product (the mechanical sealer) using the fluorescent method (FPI) and to identify the root of this incompatibility using quality management techniques (5W2H method, Ishikawa diagram, 5Why method). Design/methodology/approach: To identify the root of incompatibility in the product the quality management techniques were used, i. e. 5W2H method, Ishikawa diagram and 5Why method. The subject (the mechanical sealer) on which being incompatibility (porosity cluster) was identified, was made from 410 steel. The problem in which the porosity cluster was identified after the fluorescent method (FPI). Findings: It has been shown that integrating NDT with the selected quality management techniques is an effective way to identify the problem and the root of its creation. Practical implications: This approach can be used in enterprises to analyze different types of products and incompatibilities. Originality/value: It was proposed to integrate the NDT tests with the selected quality management techniques. This integration allows identify the root of the problem and achieving the needed quality of the product.

    Opis:
    As part of continuous quality improvement in well-managed enterprises, identifying unconformity should initiate actions to find their causes. Therefore, it was proposed to the enterprise located in Podkarpacie to use in the sequential way the Ishikawa diagram and 5Why method. The aim was to analyse of unconformity (porosity cluster) on the turbine outlet nozzle and identify the root of its creation. In the enterprise, the quality analysis of the products with a fluorescent method was carried out, but after identifying the unconformity, non-analysis of their reason for their occurrence was not practiced. Therefore, it was intentional to propose the use of sequence i.e. Ishikawa diagram and 5Why method to identify the root of unconformity. The subject of study was the turbine outlet nozzle, on which the fluorescent method the porosity cluster was identified. With the use of the Ishikawa diagram, the main cause of the problem was pointed (unconformity during production), and by the 5Why method the root cause of the problem, i.e. unconformity material from the supplier, was identified. The proposed method sequence is a simple and effective way to make analyses of unconformities and it can be used in different products and service enterprises.

    Opis:
    Sustainable development encourages companies to anticipate actions that will help reduce their negative impact on the environment, but will also be beneficial to customers in terms of meeting their expectations. Hence, the purpose was to define the actions that can be expected from SMEs from the V4 countries when improving products and minimizing the negative impact on the natural environment. The research tool was a survey, the presented results of which were obtained from March to September 2023. They included 379 SMEs from the Visegrad Group countries, i.e. Poland, Slovakia, the Czech Republic, and Hungary. The results were analyzed using statistical tests performed in STATISTICA 13.3. For this purpose, the ANOVA test (repeated measurement designs) and the Mann Whitney U test were used to analyze statistically significant differences between the test results. Analyzes were performed at the significance level of α=0.05. The analysis showed that entrepreneurs from the V4 countries expect relatively different actions from SMEs when improving products and minimizing the negative impact on the natural environment. The results from the analysis may be useful in planning sustainable activities in SMEs from the V4 countries, so that these activities contribute to improving the quality of products and at the same time minimizing the negative environmental impact.

    Opis:
    Effective quality management of the product is an element that allows profit within the enterprise. Identifying unconformity and establishing their source enables quality. However, identifying unconformity is sometimes neglected. Such was evident in the analysis of the service-manufacturing enterprise located in Podkarpacie. In the enterprise, quality was assessed via non-destructive testing (via fluorescence), but decisions on sources of non-compliance were made without utilizing additional methods that allow source identification. Hence, the way of recognizing unconformity was not precise. Therefore, method sequence (Ishikawa diagram and 5Why method) approaches were proposed to enable this. The aim of this paper is to show the effectiveness of such approaches in identifying sources of unconformity. The subject of study was tubing that is used in aircraft engines. Via the applied analysis, the unconformity in production and the source cause was traced to material supplied from outside. The proposed method sequence approach can be used in other enterprises for quality analyses purposes.

    Opis:
    Identifying inconsistencies and taking adequate actions to eliminate them is an effective way to improve the quality of products. Casting products are one of the items commonly manufactured in the foundry industry. Determining their quality becomes problematic due to a large number of factors affecting them during production which can generate various types of incompatibilities. The problem with a large number of incompatibilities of castings arose in a company in the southern part of Poland. The aim of the research was to diagnose the state of a batch of castings of industrial robot arm parts and to precisely determine the most important reasons for the occurrence of unworthiness, in relation to which appropriate preventive measures could significantly contribute to the reduction of the number of non-compliant castings and hence, waste. The analysis of incompatibilities occurring in the casting using the Pareto-Lorenz method and the ABC method allowed indication of the most important (in terms of frequency and severity) incompatibility of castings - gas porosity. Continuing the analysis of the problem by means of a brainstorming session and organizing ideas via the Ishikawa diagram made it possible to identify the key cause of the problem, which was the inadequately prepared (wet) core of the casting mold.
