    Opis:
    Purpose: The aim of the work was to propose the integrated decision method with quality techniques to precision identify the root of the problem. Design/methodology/approach: The proposed method was integrated methods as the Ishikawa diagram, 5Why method and AHP method. An idea of the proposed method was improving the process of identifying the problem by using a new mixed-method, ie. after Ishikawa diagram the methods 5Why and AHP. Findings: It was demonstrated, that it is purposeful using the proposed mixed method (ie. qualitative and quantitative) to expand the horizon of identifying the root cause. Research limitations/implications: The limitation is the subjectivism of the entity using the method, which is revealed during assessing the causes of a problem. Therefore, future works will be based on the minimalization of subjectivism by using the fuzzy Saaty scale. Practical implications: The proposed method is a new approach to analyse different types of problems and support the process of solve decision problems. Therefore, this method can be practice in service and production enterprises to identify the root of product incompatibility. Social implications: Using the method allows improving the process of making the decision about causes of the problem, and limits the possibility of wrong decision about the source of the problem. Originality/value: The proposed method was used a new proposal of mixed-method, ie. it was used integrated the Ishikawa diagram, 5Why method and AHP method. The presented method is some kind of a new approach to identify the root of the problem.

    Opis:
    Analysis of the incompatibilities occurring in an organization relies on identifying the problem and then applying the appropriate corrective and improvement actions. It is possible by using appropriate instruments of quality management and, basically, their sequence, which is a modern way of solving the problem, and it enables the improvement of functioning of an enterprise. Therefore, it is advisable to select an appropriate group of quality management instruments and use them in the appropriate sequence, because then they are complete and lead to full analysis and conclusions adequate to the problem. The aim of the article is to analyze the correlation and influence of the selected factors on the incompatibilities in selected processes, i.e. the production process of furniture fronts and furniture in general. Moreover, the idea is to use the appropriate sequence of instruments of quality management to solve various types of incompatibilities. The analysis was made at a company where a lot of different kinds of incompatibilities in processes were identified within 9 months. It was important to solve the problem for this enterprise because it was generating relatively large financial losses, and the lack of identified causes of the problem precluded taking preventive actions and developing the enterprise. After the initial analysis of the processes and problems, it was decided to use the correlation analysis, the Pareto-Lorenz diagram, the 5W2H method, the Ishikawa diagram and the 5Why method. The methodology and conclusions drawn from the analysis may be useful in solving complex problems at other production and service enterprises.

    Opis:
    Purpose: The analysis process of the causes of the problem by often used the Ishikawa diagram is not effective when knowledge is lacking with regard to the particular causes and their validity about the problem. Moreover, its subjectivity is affected by the people undertaking the analysis. The aim of this paper is to reveal ways of improving the analysis process of problem causes by utilising the new method of integrated techniques, i.e.: Ishikawa diagram and FAHP method. Design/methodology/approach: An analysis process of problem causes was made by utilizing the integrated techniques, i.e.: Ishikawa diagram and FAHP method. The problem was identified after the FPI method, and it was a linear indication on the bearing cover from 410 steel. Findings: It was shown that implementing the FAHP method in the Ishikawa diagram allows a numerical analysis of the main causes of the problem. Research limitations/implications: Future analysis should be undertaken by applying the 5Why method, in order to fully identify the root cause of the problem. Practical implications: A new method can be used to precisely and reliably analyse different types of problems. Social implications: This method is an effective tool that supports the process of analysing the causes of the problem, and thus the process of making multi-criteria decisions. Originality/value: The article proposes a new method for integrating analysis techniques, i.e. the Ishikawa diagram and the FAHP method, which can be effective in precisely and reliably assessing the causes of the problem.

    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:
    Purpose: The aim of the study is to analyze environmental awareness among employees of companies producing plastics, and subsequently to draw conclusions about the level of their pro-environmental awareness. The motive for the implementation of pro-environmental awareness research in plastics-producing plants was their harmful impact on the environment. Design/methodology/approach: The research was a survey that was carried out among 44 workers of plastics enterprises located in south-eastern Poland in the first quarter of 2018. During the selection of companies for research, it was included: their location (south-eastern Poland), long-term operation (more than 30 years), the same type of activity (production of plastics), and whether pro-environmental activities were practiced. Findings: It was concluded that the level of awareness of the employees of plastic industry employees was on a low level. Research limitations/implications: The research sample is only a preliminary sample. It is planned to obtain data from a larger number of companies and verify the data. Practical implications: Enterprises should focus on meeting customer needs and maintaining high-quality products, but taking into account pro-environmental measures that should be a priority. This is possible if pro-environmental awareness is continually shaped. Social implications: The pro-environmental awareness is small among employees from the enterprises, in which pro-environmental actions were not practiced. Employees do not know how the processes are carried out in the company and whether they have any impact on the natural environment. Additionally, the employees of companies not used pro-environmental activities are unaware of the threats resulting from the activities of their company and do not know that other companies about the same activities already apply such activities. Originality/value: These results will allow better decisions in the context of sustainability and improvement actions to achieve a higher level of awareness among the plastic production companies' employees.

    Opis:
    Purpose: The purpose was to develop an approach to predict product quality considering current customers' expectations. Design/methodology/approach: The approach includes integrated techniques, i.e.: SMART(-ER) method, a questionnaire with the Likert scale, brainstorming (B&M), WSM method, and Naïve Bayes Classifier. This approach refers to obtaining customers' expectations for satisfaction from the current quality of products and the importance of these criteria. Based on the satisfaction of customers, the quality of the product was estimated and classified. Then, the quality of the product was predicted for current customers. Findings: It was shown that it is possible to predict product quality based on current customer expectations, and so based on the current existing product. Research limitations/implications: The proposed approach does not include the possibilities of determining the expected quality of the product. The approach focuses on predicting customers' satisfaction with the current quality of the product. Therefore, if there is a need for improvement actions, further analyzes should be carried out to determine which criteria should be modified and how. Practical implications: The presented approach can be used for any product. Therefore, it is a useful tool for any kind of organization, which strives to meet customer satisfaction. Despite the possibility to predict the quality of the product, the proposed approach can indicate at an early stage to the organization that it is necessary to make improvement actions. Social implications: It is possible to reduce the waste of resources by predicting that improvement actions are necessary. Moreover, the approach supports an entity (e.g., expert, enterprise, interested parties) in predicting current customers' satisfaction. Originality/value: Originality is predicting product quality based on current customers' expectations. A new combination of quality management techniques, decision support, and machine learning was implemented.

    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.

Design/methodology/approach: The research method applied in article is mainly standardized survey research making based on survey conducted in contact and remote way conducted in 78 enterprises in south-eastern Poland. The research process also accompanied analysis of thesource documentation. Findings: It was concluded that decision during improving quality of the product were making mainly in simultaneously with considering customers' requirements of the customers about the quality of the products and the impact of products on the natural environment. Research limitations/implications: Most of the verified enterprises from SMEs are tried integrating qualitative-environmental actions as part of improving the quality of products. This is a favorable condition for further research, so that it is possible to adjust the quality and environmental approach when improving the quality of products in SMEs. Practical implications: Discussion of the results of research have a series of practical implications mainly for product management staff. Especially in organizations that designed new products or also in significant modification of these products. Social implications: Building awareness improves not only quality of products, but also simultaneously in line with sustainable development, including in improving environmental aspects. Originality/value: The article has cognitive value for development of knowledge, science, quality, and environmental in the area of management of products.

    Purpose: The main goal of the research was to determine the spectrum of instruments supporting management processes that are used to improve the quality of products in terms of sustainable development. We analyzed the degree of their use in the practical functioning of the surveyed enterprises. In addition, the aim of the research was to determine the scope of application of the indicated instruments or the possibility of their use in the decision-making process relating to the improvement of the broadly understood quality of products. Design/methodology/approach: The research method applied are: 1) standardized survey research making based on a survey conducted in contact and remote way conducted in 78 enterprises in south-eastern Poland; 2) analysis of the source documentation and in-depth interviews. It is a component of broader research. Findings: The following methods were used in decision-making processes with varying frequency: the Delphi method by 58% of respondents, Tree of Failure Analysis (by 52%), Event Tree Analysis (by 44%), and the QFD method (by 41% respondents). The surveyed companies that have implemented a vapour management system based on ISO standards tend to use 5 methods out of 25 cited in this study (these are a survey, brainstorming, 5Why and/or 5W2H, benchmarking, and the Delphi method). As a result of using mainly the above mentioned methods in decision-making processes, 74% (out of all) of the respondents indicated an increase in the quality level of products, and 39% of respondents indicated the enhancement of the pro-ecological impact of products on the natural environment. Research limitations/implications: Most of the analysed enterprises from SMEs are tried integrating qualitative-environmental actions as part of improving the quality of products. This approach is crucial when improving the quality of products in SMEs. Practical implications: It is necessary to develop a multidimensional modl enabling the optimization of decision-making processes with the possibility of making full use of the available instruments for improving the quality of the product in such a way as to meet the rapidly changing requirements of stakeholders. Originality/value: The article has cognitive value for development of knowledge, science, quality, and environmental in the area of management of products.
