“…As proved with published knowledge [10,17,[100][101][102][103][104], employees of railway undertakings may contribute to the risk reduction on one hand and they may represent a risk factor themselves on the other hand. Respecting the ideas of García-Alcaraz, the appropriate implementation of Lean principles requires an education process and human knowledge [105]. The underestimation of risk factors and subsequently risks which result from an inappropriate approach of employees may negatively impact the quality of business culture.…”

The sustainability of services in undertakings which operate in railway passenger transport is closely connected with efforts to provide high-quality and time-acceptable services to the customer, to achieve lean processes, to standardise work processes, to eliminate wastage and to avoid those activities which do not add any value. Considering its ecological nature and big volume of passenger transport, railway passenger transport represents an irreplaceable sustainable system for the future. These facts and the entry of new railway carriers into this system highlight the importance of managing risks in a progressive way. This article focuses on the options of risk management when versatile and flexible tools, such as Lean tools, are set correctly. The aim of this article is to introduce a proposal for the application and a specific application of Lean philosophy in risk management which impacts train delays in railway passenger transport. From the point of view of quantitative data analysis, multiple mathematical-statistical tests have been used to assess data (e.g., Anderson–Darling test, Kolmogorov–Smirnov test, Jarque–Bera test, two-tailed test, Grubbs’s test and Thompson Tau test). Also, descriptive statistics and ANOVA test (Analysis of Variance) have been applied in the process of evaluating the monitored attributes. In order to assess the data dependency, Chi-Square Test and a correlation analysis have been applied. The research outcomes focus on highlighting the need for a systematic approach for train delays and to avoid delays through risk management. The case study applies selected Lean methods to monitor train delays in selected stations within the main railway corridor of the Slovak Republic for the period from 2015 to 2018. In 2019, the results were processed and created a basis for proposing a unique software tool like an aid for risk management in the case of train delays using Lean philosophy. The flexible software includes the participation of employees, and at the same time, it respects the needs of customers. The research results provide grounds for further study of risks in a challenging environment of railway undertakings, with different types of trains, railway stations as well as entire railway networks. The processed results of the article represent valuable material for railway undertakings not only in Slovakia but also for railway organisations in V4 countries.

“…In this sense, Caro Soto [73] highlighted that Mexican companies are currently developing a digital environment incorporating ICT in SC operations, managing information to generate competitiveness and productivity within the organization. With this, SC partners are motivated and confident since the information is reliable and timely to implement the Planning activities and the Execution and Control of operations, thereby reducing uncertainty, as indicated by García-Alcaraz et al [74]. With all of this, procurement, production, distribution, and demand can be coordinated by Planning requirements and capacities simultaneously with ICT implementation [68].…”

“…The findings allow us to conclude that ICT integration is crucial in the company's activities, as indicated by the company's CEOs, who mention that, especially in the SS, technologies help to Control through the wireless information transfer to track goods in real-time. García-Alcaraz et al [74] also indicates that, by accelerating the transfer of information by integrating ICTs in the operations of the different stages of Planning, Execution, and Control applied within the SC processes, the Benefits associated with increased efficiency, quality, and accuracy of information are expected, where better decision-making is finally expected.…”

This paper reports a second order structural equation model (SEM) with four latent variables and six hypotheses to analyze the Planning, Execution, and Control of the information and communication technologies (ICT) implementation in supply chains (SC) and the operational Benefits obtained. The model is validated with information obtained from 80 responses to a questionnaire applied direct to manufacturing companies in Baja California state (Mexico), specifically in Ensenada, Mexicali, Tecate, and Tijuana municipalities. The variables are statistically validated using the Cronbach’s alpha index for internal and R-squared for predictive validity. Partial least squares algorithms are used to validate the model’s hypotheses in software WarpPLS version7.0 ScripWarp Systems, Laredo, TX, US. Findings indicate that the direct impact of Execution and Control is positive and therefore are the basis for successful integration of ICT and obtaining agility and flexibility benefits in the SC.

“…Their implementation without adaptation to the environment may be another factor of failure. Garcia-Alcaraz et al (2017), for example, conducted an analysis to combine human factors with operational benefits. Based on the assumption that Six Sigma is a philosophy related to human resources and that it depends on management decisions, supporting organisational structure, and implementation strategy, we can state that the implementation of the Six Sigma concept is strongly influenced by the level of soft skills of human resources.…”

Most small and medium-sized enterprises in the furniture industry use simple partial approaches to improve or manage production processes. The article aims to present research results focused on continuous process improvement through the implementation of Six Sigma (SS) and Lean Six Sigma (LSS) concepts in furniture production. Their impact on the performance via the level of the ROE (Return on Equity) indicator was evaluated using statistical methods of Chi-square test and Cramer's contingency coefficient. The results of the research showed that furniture enterprises that had implemented selected methods of quality management reached a medium level of ROE values. The absence of a more comprehensive approach to managing the performance of processes was the impulse for a model creation based on the interconnection of SS and LSS concepts. The model should a practical use of appropriate methodologies and procedures in the management of furniture production processes, as well as in their optimisation. A thorough analysis of nonconforming products performed in furniture manufacturing processes transformed into SS and LSS metrics and the implementation of the model in the enterprise led to reduced process waste by reducing the number of non-conforming products, reducing the cost of such products, and increasing the capability of critical processes. Implications for Central European audience:The combination of theoretical knowledge in performance management and quality of production processes and practical knowledge from the real implementation of methods and tools for continuous improvement of production process capability in the company proved to be a good basis for creating a model within SS and LSS. These facts have contributed to the development of scientific knowledge. The presented application of methods and tools within SS and LSS will provide instructions for the use of new management methods. The specific outputs of the research work improve defining problems, measuring process parameters, analysis of measured data, improving furniture production processes.
