Abstract

Purpose

The benefits of adopting lean manufacturing for leveraging corporate sustainability have been highlighted in the literature. However, these studies have neglected the social side of sustainability compared with the attention given to the environmental aspects. Addressing this gap, this paper aims to investigate the influence of lean practices on the dimensions of employee social sustainability (ESS), which enabled the identification of the most critical practices.

Design/methodology/approach

This paper conducted an exploratory study in two phases: first, seeking evidence in the literature, and second, applying the analytic hierarchy process (AHP) to connect ESS to lean practices based on expert opinion.

Findings

From the literature review, this paper found linkages between eight lean manufacturing practices and four dimensions of ESS. Based on evidence from the literature, the authors designed and applied an AHP model to set priorities among lean practices and social dimensions. Therefore, “health and safety” was evaluated as the most critical social dimension, and 5S was considered the most influential lean practice on ESS.

Originality/value

This study contributed to introducing the perspective of lean manufacturing practices as enablers of ESS. Notably, it pointed out which specific practices should be prioritized in the lean implementation process with social sustainability purposes. In addition, it identified relationships not reported in the literature, raising questions for further investigation.

Abstract

Purpose

Although there are general methodologies for lean implementation in manufacturing companies, a specific methodology for the implementation of lean healthcare in hospitals has not been addressed by the literature. Addressing this gap, the purpose of this paper is to develop a practice-driven methodology for implementing lean in hospital operations.

Design/methodology/approach

Three case studies were conducted to collect evidence on the lean implementation process in Brazilian hospitals. From empirical evidence and literature, the implementation methodology was proposed and submitted to critical assessment by experts from the field.

Findings

The process of lean implementation was very similar in all cases, triggered by strategic planning and operationalized by continuous improvement projects. On the other hand, in all cases, the lean implementation teams had to deal with employees’ resistance. These findings were valuable inputs to the development of the implementation methodology. After refinement, it was proposed a feasible, useful and user-friendly methodology.

Research limitations/implications

The proposed methodology was raised from the practice through case study research. However, the proposed methodology was not fully applied, and the associated performance measures were not elaborated in this paper. Therefore, more case studies and applications will be necessary to generalize the findings.

Practical implications

The methodology provides practical guidelines that support lean implementation in hospital operations. Although it demands adaptations for each specific hospital setting, this initial step may encourage hospital managers to start the lean journey.

Originality/value

This study addressed the gap in the literature regarding the lack of methodologies for implementing lean healthcare in hospital operations. The methodology synthesizes the knowledge, principles and tools of lean thinking that can be applied in hospital operations.

Abstract

Purpose

Developing a lean supply chain is a continuous improvement effort, so it requires tracking the implementation progress by assessing the achieved level of leanness. However, lean supply chain practices depend on firm-to-firm relationships and an assessment method should consider these network interactions. Given the absence of such a method, this study aims to propose an alternative approach for assessing the leanness level of supply chains.

Design/methodology/approach

The authors extracted 18 typical lean supply chain practices from the literature, constituting the leanness assessment parameters. Then, the authors developed an assessment method based on the graph-theoretic approach due to its properties of capturing the interdependencies between elements of a system. The authors tested the proposed method in an automotive supply chain, selecting the focal firm and three of its first-tier suppliers.

Findings

The authors positioned partial and overall results in a visual classification scale and the supply chain presented a moderate leanness level. After empirical testing, the proposed method demonstrated its practical feasibility.

Research limitations/implications

This paper contributes to the literature with a novel approach for supply chain leanness assessment. However, to increase its generalizability, it would be beneficial to test the method in non-automotive supply chains, extending the assessment scope to downstream firms and second-tier customers and suppliers.

Practical implications

For practitioners, this paper provides a self-assessment tool to monitor the supply chain leanness and set priorities for improvement.

Originality/value

Besides tackling the interrelationships between firms, the proposed method considers the interdependencies between lean practices, providing partial and overall feedback to enable a systemic assessment.

Abstract

Purpose

Studies addressing barriers to implement lean production (LP) from the perspective of risk management (RM) have not been so usual in the literature. Re-interpreting barriers to lean as potential risks that should be avoided or mitigated, this paper aims to identify and categorise risks in the implementation of LP to propose a framework, which provides an overview of risks that negatively influence this process.

Design/methodology/approach

Through a systematic literature review exploring papers in the Web of Knowledge database, 69 papers were selected. A descriptive analysis was first carried out to identify the evolution in the number of papers, usual terminologies, research methods, analytic tools and the RM phases approached by each paper. After that, an in-depth study of the paper sample was conducted to find risk factors and categories.

Findings

The authors found a list of 61 risk factors. Then, considering the sources of the identified risk factors, six broad categories of risks were defined, namely, top management risks, human resources risks, lean knowledge risks, technical risks, supply chain risks and cultural risks. The authors also defined 34 subcategories, resulting in a risk classification framework.

Research limitations/implications

Based on the review, the authors identified literature gaps and provided a research agenda. A noteworthy research limitation is that the authors only selected papers about LP, so the authors might have missed some potential risks in lean implementation that may arise from other-related areas. Thus, the exploration of lean risks adopting other perspectives may constitute a promising pathway for further research.

Practical implications

The classification framework may help practitioners and researchers in risk identification, evaluation and mitigation. It can also enable the creation of response plans to risks in lean production implementation, as it indicates the potential risks that may be faced along with this process.

Originality/value

This study contributed to add the perspective of RM to the literature on lean implementation. The introduction of RM concepts and tools may generate more robust models of lean implementation. Therefore, the classification framework may represent a starting point to produce new knowledge about this research topic.

Abstract

Purpose

The paper aims to present a hands‐on activity for operations management (OM) education that simulates assembly operations common in industrial settings using polyvinyl chloride (PVC) threadable fittings utilised in water pipes as interchangeable parts for easy manual assembly.

Design/methodology/approach

The teaching method followed the philosophy of active learning and was applied in an action research approach; the proposed activity was tested and improved during applications in the classroom.

Findings

The applicability of the method was proven during in‐class exercises. The results were confirmed with positive feedback from the students involved in the exercises, which was obtained through a survey conducted after a set of applications.

Research limitations/implications

Although the proposed activity may have several possibilities for application, this paper focuses specifically on teaching the topics of work measurement and assembly line balancing, thus limiting the generalisability of these findings to other OM techniques. Therefore, it is important that the activity is further adapted to teach other OM topics.

Practical implications

The activity performed with pipe fittings represents a practical exercise that contributes to reduction of the gap between theory and practice in OM education. Using simple and low cost materials, the students are involved in creating a real process from a fictional product.

Originality/value

This paper presents an experiential learning exercise applied using an innovative approach, using pipe fittings as interchangeable parts assembled in a production line.

Abstract

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

Abstract

Purpose

From the agency theory’s point of view, this paper aims to analyze corporate governance mechanisms about the characteristics of the companies quoted in the segments Bovespa Mais and Bovespa Mais 2 and their influence on the creation of value in preparation for the opening of the initial public offering (IPO).

Design/methodology/approach

A quantitative approach was adopted to achieve the proposed objective using the panel data with fixed effects and secondary data collected on the Comissão de Valores Mobiliários website, using statistical software Stata® 13.0 for statistical tests. The population comprises non-financial companies belonging to the Bovespa Mais and Bovespa Mais Level 2 groups, as the survey sample took into account the period of adhesion of the companies, totaled in 15 companies, which cover the period from 2008 to 2019. The selected variables correspond to the ownership structure’s characteristics, then the board’s composition and the fiscal council as the body responsible for supervising the administrators’ acts.

Findings

The main results indicate that the number of independent members on the board of directors and the supervisory board’s participation positively influence market performance. However, it also reveals that the concentration of ownership brings fundraising for other companies’ acquisitions, risk reduction concerning information asymmetry between investing powers.

Research limitations/implications

The main results indicate that the number of independent members on the board of directors and the supervisory board’s participation positively influence market performance. Despite this, it also reveals that the concentration of ownership brings fundraising for other companies’ acquisitions, risk reduction concerning information asymmetry between investing powers.

Practical implications

This paper advances a comparative institutional perspective to explain capital market choice by firms making an IPO in a foreign market. This paper finds that internal governance characteristics (founder-chief executive officer, executive incentives and board independence) and external network characteristics (prestigious underwriters, degree of venture capitalist syndication and board interlocks) are significant predictors of foreign capital market choice by foreign IPO firms.

Social implications

While product market choices have been central to strategy formulation for firms in the past, financial markets’ integration makes capital markets an equally crucial strategic decision. This paper advances a comparative institutional perspective to explain capital market choice by firms making an IPO in a foreign market.

Originality/value

This situation generates value to shareholders and is perceived by the market and, ultimately, generates a direct relationship with the market performance of companies. While product market choices have been central to strategy formulation for firms in the past, financial markets’ integration makes capital markets an equally major strategic decision.

Abstract

Purpose

Lean Six Sigma (LSS) implementation follows a structured approach called define-measure-analyze-improve-control (DMAIC). Earlier research about its application in emergency healthcare services shows that it requires organizational transformation, which many healthcare setups find difficult. The Kotter change management model facilitates organizational transformation but has not been attempted in LSS settings till now. This study aims to integrate the LSS framework with the Kotter change management model to come up with an integrated framework that will facilitate LSS deployment in emergency health services.

Design/methodology/approach

Two-stage Delphi method was conducted by using a literature review. First, the success factors and barriers of LSS are investigated, especially from an emergency healthcare point of view. The features and benefits of Kotter's change management models are then reviewed. Subsequently, they are integrated to form a framework specific to LSS deployment in an emergency healthcare set-up. The elements of this framework are analyzed using expert opinion ratings. A new framework for LSS deployment in emergency healthcare has been developed, which can prevent failures due to challenges faced by organizations in overcoming resistance to changes.

Findings

The eight steps of the Kotter model such as establishing a sense of urgency, forming a powerful guiding coalition, creating a vision, communicating the vision, empowering others to act on the vision, planning for and creating short-term wins, consolidating improvements and producing still more change, institutionalizing new approaches are derived from the eight common errors that managers make while implementing change in the institution. The study integrated LSS principles and Kotter’s change management model to apply in emergency care units in order to reduce waste and raise the level of service quality provided by healthcare companies.

Research limitations/implications

The present study could contribute knowledge to the literature by providing a framework to integrate lean management and Kotter's change management model for the emergency care unit of the healthcare organization. This framework guides decision-makers and organizations as proper strategies are required for applying lean management practices in any system.

Originality/value

The proposed framework is unique and no other study has prescribed any integrated framework for LSS implementation in emergency healthcare that overcomes resistance to change.

Abstract

Purpose

The purpose of this paper is to analyze the attitudes of meat consumers in Rio Grande do Sul, Brazil, concerning cultured meat. This State is characterized by its strong cultural identity and social practices, barbecue being its typical dish.

Design/methodology/approach

The authors applied a cross-sectional survey with meat consumers residing in Porto Alegre/RS, the sample of which, composed of 538 individuals, expressed the population heterogeneity. The data were analyzed using the Pearson chi-square, Cramer's V, and correspondence analysis.

Findings

The results demonstrate that although six of ten people were willing to try cultured meat, only four of them responded positively to the willingness to consume it over conventional meat. Young individuals demonstrated a favorable attitude towards the product, expressing a greater propensity both to try it and to include it in the diet regularly. However, the rejection of cultured meat gradually intensified after 40 years old. The previous knowledge and familiarity with the investigated subject are not predictive of the intention of experimentation so that almost two-thirds of the individuals who did not know the product were positively willing to try it.

Originality/value

Despite the recent intensification of studies about consumer behavior towards cultured meat, its analysis in a context in which meat historically plays a fundamental role in socioeconomic development is still little explored. The originality of our research is circumscribed by the understanding of the behavior of meat consumers, members of a culture where it plays a central role.

Abstract

Purpose

This paper aims to analyse the influence of the thickness of different layers [diamond-like-carbon (DLC) and chromium nitride (CrN)] on the sliding wear behaviour of a multifunctional coating on AISI 1020 substrates. When small and cheap components need to be manufactured in large scale, they are often produced using soft metals, such as unhardened low carbon steels and pure iron.

Design/methodology/approach

Two families, one with thicker films and the other with thinner films, were deposited onto a soft carbon steel substrate by plasma-enhanced chemical vapour deposition (PECVD). Reciprocating linear tests with incremental loading assessed the durability of the coatings. In addition, friction coefficient and wear rates of both specimens and counterbodies were measured at a constant load.

Findings

Thinner layers presented lower sliding wear rates (four-five times lower) for both specimens and counterbodies, less spalling and protective tribolayers on the wear tracks.

Originality/value

Although multilayered CrN–DLC coatings on relatively hard substrates such as HSS and cemented carbide tools are already a proven technology, much less is known about its deposition on a much softer substrate such as low carbon steel. In previous works, we have analysed the influence of layer thickness on hardness and scratch resistance of the same coatings. This paper presents results for their performance under wear sliding conditions using an original approach (three-dimensional triboscopic maps) for two distinct configurations (increasing load and constant load).
