The purpose of this paper is to explore the applicability of lean construction (LC) concepts and tools in necessary, but non-value-added activities (NVAA) in small and medium-sized enterprises (SME). The application of the lean tools in this way facilitates the flow of information and handling material, improving productivity, quality and performance. Finally, practical results motivate a discussion on the real potential of LC principles and on the challenges related to its implementation.

The methodology makes use of direct involvement in the environment under study. Some of the activities performed were the value stream mapping and time and motion studies of the company’s process selected, identification of wastes and the proposition of improvements to be implemented.

The main findings are related to the benefits of the application of LC not only in value-added activities but in activities that can influence the development and workforce planning, especially for SME businesses. This company should be able to achieve better management decisions and results after implementing the LC principles, overcoming the limited resources.

This proposed method helps in overcoming the lack of systematic procedures, enabling LC in activities that not add value properly. It has the advantage of integrating existing tools and models effectively, which not only improve the shortcomings of the conventional methods but also result in more convenient calculation and application.

This paper aims to explore synergies between lean production (LP) and six sigma principles to propose a lean six sigma (LSS) framework for continuous and incremental improvement in the oil and gas sector. The Three-dimensional LSS framework seeks to provide various combinations about the integration between LP principles, DMAIC (define–measure–analyse–improve–control) cycle and plan-do-check-act (PDCA) cycle to support operations management needs.

The research method is composed of two main steps: diagnosis of current problems and proposition of a conceptual framework that qualitatively integrates synergistic aspects of LP and six sigma and analysis of the application of the construct through semi-structured interviews with leaders from oil and gas companies to assess and validate the proposed framework.

As a result, a conceptual framework of LSS is developed contemplating the integration of LP and six sigma and providing a systemic and holistic approach to problem-solving through continuous and incremental improvement in the oil and gas sector.

This research is different from previous studies because it integrates LP principles, DMAIC and PDCA cycles into a unique framework that fulfils a specific need of oil and gas sector. It presents a customized LSS framework that guides wastes and cost reduction while enhancing quality and reducing process variability to elevate efficiency in operations management of this sector. This is an original research that presents new and original scientific findings.

This paper aims to examine the relationship between the implementation of soft lean practices and organizational resilience development in the service sector.

A mixed-methods explanatory design that relied on two sequential and complementary phases was adopted. In the first phase, a quantitative analysis was performed based on data collected from practitioners from service organizations, allowing the identification of the significance of this relationship. In the second phase, the authors used semi-structured interviews with experts to qualitatively assess how this relationship occurs.

Findings indicated that soft lean practices are positively associated with organizational resilience, although the extent of their relationships varies depending on the resilience ability under analysis. Interviews with experts also provided specific details on how such relationships occur, adding insights to the numerical results.

This study provides a deeper understanding of the implications of lean management, specifically concerning the support of soft lean practices to develop organizational resilience. Additionally, the identification of this relationship (and how it occurs) allows service organizations to deploy human-related strategies to promote broader adoption of certain soft lean practices. As socio-cultural changes are usually time-consuming, anticipating these organizational resilience needs may result in competitive advantages in the face of disruptive events.

The purpose of this paper is to explore how rising technologies from Industry 4.0 can be integrated with circular economy (CE) practices to establish a business model that reuses and recycles wasted material such as scrap metal or e-waste.

The qualitative research method was deployed in three stages. Stage 1 was a literature review of concepts, successful factors and barriers related to the transition towards a CE along with sustainable supply chain management, smart production systems and additive manufacturing (AM). Stage 2 comprised a conceptual framework to integrate and evaluate the synergistic potential among these concepts. Finally, stage 3 validated the proposed model by collecting rich qualitative data based on semi-structured interviews with managers, researchers and professors of operations management to gather insightful and relevant information.

The outcome of the study is the recommendation of a circular model to reuse scrap electronic devices, integrating web technologies, reverse logistics and AM to support CE practices. Results suggest a positive influence from improving business sustainability by reinserting waste into the supply chain to manufacture products on demand.

The impact of reusing wasted materials to manufacture new products is relevant to minimising resource consumption and negative environmental impacts. Furthermore, it avoids hazardous materials ending up in landfills or in the oceans, seriously threatening life in ecosystems. In addition, reuse of wasted material enables the development of local business networks that generate jobs and improve economic performance.

First, the impact of reusing materials to manufacture new products minimises resource consumption and negative environmental impacts. The circular model also encourages keeping hazardous materials that seriously threaten life in ecosystems out of landfills and oceans. For this study, it was found that most urban waste is plastic and cast iron, leaving room for improvement in increasing recycling of scrap metal and similar materials. Second, the circular business model promotes a culture of reusing and recycling and motivates the development of collection and processing techniques for urban waste through the use of three-dimensional (3D) printing technologies and Industry 4.0. In this way, the involved stakeholders are focused on the technical parts of recycling and can be better dedicated to research, development and innovation because many of the processes will be automated.

The purpose of this study was to explore how Industry 4.0 technologies are integrated with CE practices. This allows for the proposal of a circular business model for recycling waste and delivering new products, significantly reducing resource consumption and optimising natural resources. In a first stage, the circular business model can be used to recycle electronic scrap, with the proposed integration of web technologies, reverse logistics and AM as a technological platform to support the model. These have several environmental, sociotechnical and economic implications for society.

The sociotechnical aspects are directly impacted by the circular smart production system (CSPS) management model, since it creates a new culture of reuse and recycling techniques for urban waste using 3D printing technologies, as well as Industry 4.0 concepts to increase production on demand and automate manufacturing processes. The tendency of the CSPS model is to contribute to deployment CE in the manufacture of new products or parts with AM approaches, generating a new path of supply and demand for society.

The purpose of the paper is to perform a review and analyze the literature on lean accounting (LA) to develop insights into how LA research is developing, offering a critique of the research to date and underlining future research opportunities.

The research uses a structured literature review (SLR) to categorize and analyze 39 research articles from relevant journals with a publication date from 1996 to 2020 (September) and to answer three research questions.

Findings demonstrated that although LA seems to be the most suitable method for lean companies, it still lacks research in terms of the role of accountants in lean organizations as well as how its concepts are integrated with the generally accepted accounting principles (GAAP).

The paper provides both academics and practitioners with valuable insights regarding the role of management accounting and accountants in the pursuit of lean transformation, presenting meaningful themes and a complete analysis of the literature along with research gaps for future research.

The paper contributes to lean manufacturing literature by providing a comprehensive SLR of articles regarding LA. Also, the paper serves as a basis for developing future research agendas in management accounting practices for lean organizations.

This study aims to present consolidated information on blockchain, which seeks to better clarify the concept of blockchain and the associated implications and characteristics.

The methodological procedure used was Grounded Theory, based on a Systematic Bibliographic Review on the adoption of blockchain in supply chain management. To add experts' opinion on the subject to the analyzed panorama, data from a survey were also considered in the analysis.

The Grounded Theory enabled the development of consolidated information on blockchain related knowledge, identifying benefits, fragilities and contributions of the concept for supply chain management.

An epistemological gap has been identified between the use of blockchain in supply chain management and a theoretical basis to support the application. The originality of this study lies in providing a proposition of this theoretical basis.
