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 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:
The research of railway track surfaces is aimed at improving the quality of railway infrastructure and providing the chance of improving the safety of driving. Therefore, it is advisable to constantly monitor track surface, but the research itself is not innovative because it is based on a known procedure. The crucial element are the techniques that allow to delve into the sources of problems. The aim of the article is to use the selected instruments of quality management to analyze the causes of track twist at high (180 km/h) speed of driving. The analysis of the causes of track twist was done on the basis of results from the measurement of one kilometer track section of the Krakow Glowny - Medyka route, which was made by using the TEC measuring device in April 2018. It was inferred that it is impossible to reach 180 km/h without track twist. In order to identify the causes of track twist it was proposed to use the selected sequence of quality management instruments, i.e.: brainstorming, Ishikawa diagram and the 5Why method. The identified causes of track twist include the abrasion of rail, scratches and exploitation point. The analysis and conclusions drawn from it may be useful in the analysis of other problems in railway transport as well as production and service industries.

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:
Making a complex analysis of the problem in order to identify the root of its occurrence, is the process burdened with the risk of uncertainty. This risk is in case of the quality analysis, in which the choice and making a decision is not confirmed by reliable information (number). This risk is in case of the quality analysis, in which the choice and making a decision is not confirmed by reliable information (number). But these techniques do not include the risk of uncertainty, so their sequence should be expanded about the appropriate method, to take this into account. It was considered beneficial to demonstrate that this method is the Fuzzy Analytic Hierarchy Process method (FAHP). The aim of the study to implement the FAHP method in the sequence of traditional quality management techniques (Ishikawa diagram and 5Why method) and proposition new, not practiced yet the method to complex analysis of the problem and identify the root of its root cause. The subject of the study was the furniture front, on which the incompatibility was identified (shortened foil). From the categories to which the potential causes of the inadequate foil were assigned, by using the Ishikawa diagram and the FAHP method in an integrated manner, were defined the most important categories (method and machine) in a precise (numerical) way. Next, using the same tools, the relationship between the potential causes was analysed and selected the main causes of the problem. Then, by using the 5Why method the root of the problem was defined (lack of the new machine and failure to comply with labor standards). The obtained results could differ depending on the subjectivity, however, the method itself proved to be effective and can be used to solve other types of the problem.

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:
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.

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.
