The concept of Lean Manufacturing is a set of techniques, methods and tools, whose application in manufacturing processes is expected to eliminate wastes and improve their economic efficiency. The challenges of Sustainable Development determine a new approach to conducting manufacturing activities. Issues related to caring for the environment and the social aspects of the business are becoming crucial from the point of view of business stakeholders. The article attempts to juxtapose the classical approach to Lean Manufacturing, presenting its main principles. The authors also highlighted the key legal and formal requirements that determine a different approach to Lean Manufacturing. The main sources of green wastage were then presented and possible ways of correlating the Lean Manufacturing (classical) concept with Lean Manufacturing seen in the light of Sustainability challenges were analysed. This combination was presented as Lean Green, thus indicating the possible relationship between Lean Manufacturing and Sustainability, in its environmental part. Using examples of specific companies, the potential benefits of implementing a Lean Manufacturing concept oriented not only on economic aspects, but above all on environmental benefits, are summarised. A review of the Polish and world literature, an analysis of available sources and the authors' own experience were used.

The role of visual management in the organization of safe work in production companies Workers play a superior role in the production process because they are responsible for its proper functioning (e.g. process efficiency, quality, technical condition of usage machines), and are also responsible for safety at work. The issue of work safety should be a crucial factor in the process of introducing changes in the company. The introduced changes should take into account safe working conditions and reduce the number of potential accidents, therefore employers should implement solutions aimed at improving work safety. One of the tools that can affect work safety is visual management (VM). The use of various forms of VM enables immediate response to emerging problems, which may translate into an increase in employees' awareness of health and safety issues. The article presents the possibilities of using of visual management tools in manufacturing companies in terms of improving work safety. The proposed solutions can be used by enterprises that register accidents at work and take actions to increase employees' awareness of occupational safety and health (OSH).

The high level of competition in the manufacturing industry requires the creation of working conditions that allow for the efficient implementation of production processes. One of the solutions enabling the adaptation of production stations to improve the work performed by employees is the implementation of a management system based on the Lean Manufacturing (LM) philosophy. The purpose of this article was to determine the potential impact of the implemented LM tools, in the form of 5S and standardization, on the efficiency of the production process in specific production conditions. The methodology of the conducted research included: obtaining data before and after the implementation of LM tools (in total 12 months). The data was used to determine the effectiveness of individual operations, and then to conduct a comparative analysis using statistical tests. It was found, among others, that the implementation of LM tools resulted in an increase in the efficiency of the manufacturing process by about 11 percentage points. The obtained results confirm the thesis that a manufacturing company, in order to maintain its position on a competitive market, can improve the efficiency of processes by using tools such as LM. The selection of tools must be adequate to the implemented processes, so that they bring measurable increase in efficiency.

Since there is so much empirical research in the field of lean manufacturing, to provide a comprehensive overview of the literature on this subject, a bibliometric analysis was required. Through science mapping and multi-dimensional bibliometric analysis, this study aims to identify common themes in the most-cited research on lean manufacturing. A bibliometric analysis was conducted using VOSviewer, including keyword occurrence, co-authorship network, and bibliometric coupling network analyses. From the 4,648 results in the SCOPUS database search, the 100 most-cited articles were analyzed. The analysis found four research clusters: “lean manufacturing,” “productivity,” “manufacture,” and “value stream mapping.” It was also found that most of the most-cited papers came from journals with a Q1 ranking. Based on these results, scholars work to learn as much as they can about the field. The results are important to researchers because they show how far the research on lean manufacturing has come. As far as the author knows, no other study has been done on bibliometric analysis of the topic. By making a scientific map of what is known about lean manufacturing, this study adds to what is already known.

The article presents the possibility of increasing the production efficiency in an enterprise dealing in the production of lounge furniture. The literature review shows that Poland is the sixth country in the world in the amount of furniture production. It is also one of the leading exporters of upholstered furniture in Europe. Each year, the value of furniture sales production increases by a few percentage points. Due to the constantly growing customer orders, many companies in this industry are struggling with delays in delivering products to customers. This problem also occurs in the analyzed company. While analyzing the production process, the occurrence of a large number of non-conformities was also noticed. An analysis was carried out to indicate the number of non-conformities and the place of their occurrence. The FMEA analysis was used, which indicated which non-conformities are the most important, and the 5Why method, which allowed to indicate the cause of their occurrence. The analysis of production processes showed which activities do not bring added value and how they can be eliminated at no cost. All these measures contributed to increasing the efficiency of the production of lounge furniture.

Value stream mapping (VSM) is a well-known lean analytical tool in identifying wastes, value, value stream, and flow of materials and information. However, process variability is a waste that traditional VSM cannot define or measure since it is considered as a static tool. For that, a new model named Variable Value Stream Mapping (V-VSM) was developed in this study to integrate VSM with risk management (RM) using Monte Carlo simulation. This model is capable of generating performance statistics to define, analyze, and show the impact of variability within VSM. The platform of this integration is under Deming’s Plan-Do-Check-Act (PDCA) cycle to systematically implement and conduct V-VSM model. The model has been developed and designed through literature investigation and reports that lead in defining the main four concepts named as; Continuous Improvement, Data Variability, Decision-Making, and Data Estimation. These concepts can be considered as connecting points between VSM, RM and PDCA.

This paper presents a solid methodology for improving the efficiency and productivity of assembly lines using Lean Manufacturing tools, in particular the Define, Measure, Analyze, Improve, and Control approach (DMAIC) and line balancing techniques, followed by a concrete application in a case study of a wiring industry assembly line. The first phase of the approach ensured a clear definition of the problem using the who, what, where, when, why, and how tool (5W1H) and a description of the manufacturing process. The measurement phase allowed the calculation of the Takt time (TT) and the timing of the cycle times of the 17 stations of the line with the use of data collected on the standardized work combination table (SWCT) documents. This facilitated the analysis phase by first establishing a Yamazumi chart showing the distribution of the load between the line's stations and allowing the identification of bottleneck stations, and then analyzing the situation through the 5-Why tools and the Ishikawa diagram. Thanks to the innovation phase and the ideal balancing conditions developed in this paper, it was possible to balance the line's stations using an action plan whose effectiveness was monitored during the control phase, improving efficiency from 78% to 95% with a saving in manpower by reducing the number of operators from 17 to 14.

Purpose: The study aim is an in-depth investigation of a Lean tools implementation sequence in an organisation as an expression of a Lean journey within that organisation. The success factors of Lean tools implementation and the relationship between them are studied. A model of Lean tools implementation in an organisation is aimed to be developed. Design/methodology/approach: A case study method is employed in this study. It is conducted in a manufacturing company from the fast-moving consumer goods (FMCG) industry. The employed method allows exploitation of a variety of techniques in the investigation process: in-depth interviews, observations, documents and data analysis. The study takes into consideration a systematic literature review and bibliometric network analysis supported by the Vosviewer software tool. Findings: The implementation of Lean Manufacturing approach, along with accompanying tools and methods, is aimed at efficiency and/or quality results of the processes within a company. Selected tools, to be successfully implemented, should support the elimination or reduction of losses related to current process flows. There are many Lean tools available, but most do not fit all organisations and all the kinds of manufacturing processes. Therefore, proper preparation before implementation is an essential issue for any organisation striving for Lean outcomes. The available Lean tools, along with their implementation sequences, are not studied comprehensively in the literature. Originality/value: An organisational-development-driven model of Lean tools implementation is elaborated, based on the literature and empirical investigations. The decision to choose the appropriate Lean tool should be guided by general organisational development. Several factors need to be considered before the implementation process, namely, capabilities, resources, gains and return on expenditure. Top management engagement, appropriate communication and listening to line employees look to be key success factors in Lean tools implementation.

Kaizen has long been known as an improvement philosophy that starts with small frequent changes to make larger changes in production. These changes come from the ideas and creative thinking of employees to ensure that the production conditions and processes are continuously improved. However, Kaizen not only helps motivate employees to think creatively with effective methods and skills, but it also helps them develop their capabilities, personality, and good work habits. The purpose of this paper is to show a new approach to human resources quality improvement through the Kaizen philosophy as a sustainable and active strategy to improve work performance. With analytical research on the relationship between Kaizen implementation, human resources quality improvement, and production efficiency and exploratory research on particular cases in manufacturing enterprises in Vietnam, the authors point out changes in production efficiency and human capacity before and after implementing improvement (Kaizen) projects. The paper finds significant changes of employee capability (Kaizen practitioners) after evaluating the human resource development process on the basis of six indicators of two groups (namely capacity development, personality development) and a set of criteria using a 5-point scale. In addition, the paper proposes a PDCA based framework with 12 contents corresponding to stages of the human resource development. This paper extends theories related to Lean Manufacturing or Kaizen, highlighting how philosophy of Kaizen has hard and soft impacts on the improvement of performance and human resources.

Purpose: The aim of the research was to assess the effectiveness of implementing Lean Manufacturing (One-Piece-Flow) elements in a company producing shock absorbers. Design/methodology/approach: With the help of VSM, the most important problem in the production process was diagnosed, and by using the 5 Whys tool, the root causes of the problems were identified. A simulation of introducing the One-Piece-Flow system into the production line was then used to estimate the most optimal solution. After choosing the solution, it was implemented, and the results obtained were verified. Findings: As a result of the conducted analyses, the most important problems related to planning, scheduling and the flow of intermediates were identified. The 5 Whys analysis allowed for the grouping of individual problems by common causes. Detailed solutions to the problems were proposed, which were included in the future Value Stream Map. Research limitations/implications: Conducting research in a working production process is limited and faces significant resistance from managers. Practical implications: The most important effects of implementing an improvement plan were minimising inventory from 138,062 units to 25,000 units, which reduced costs and indicates reduced waste. Lead time was limited to 9.67 days from 56.96 days. Originality/value: Research results confirm the effectiveness of introducing only some solutions of the Lean philosophy. This is particularly important if the enterprise is unable to comprehensively implement the Lean Manufacturing concept due to organisational or financial reasons.
