Abstract

Purpose

The brake reaction test performed on a rear axle assembly revealed that the brake flange weld could not sustain the load needed to pass the minimum requirement of the test. Evaluation of the failure mode indicated that the fracture of the weld originated at the root of the weld and cracked through the fusion zone of the weld instead of cracking through base material (toe failure). The paper aims to discuss these issues.

Design/methodology/approach

A computational methodology is presented to quantify the critical parameters to prevent throat failure. The torsion dominated loading created high in-plane shear stress on the weld which can contribute significantly to the premature failure.

Findings

The failure through the fusion zone, often termed as weld throat/root failure, was not accounted for during the design phase by numerical simulation which led to the wrong conclusion that the design will pass the test requirement. Although weld sizing and weld penetration depth can explain such unexpected failure modes, fatigue life of this particular failure was still over-predicted using the Master SN curve formulation of structural stress approach which is well established for Mode I type of failure. Accounting for the shear component in the structural stress approach led to good correlation with the test specimen. Weld throat depth is a significant parameter contributing to throat failure.

Practical implications

The failure of the weld joining the brake flange and the tube of an axle is a high severity failure mode which can result in loss of vehicle control and injury or death and hence the failure should be prevented at any cost.

Originality/value

Most of the previous work of welded components relates to Mode I loading. There is very few research performed to discuss the Mode III loading and failure. This research illustrates the importance of considering the throat failure mode and quantifies the weld parameters to prevent such failures in design applications.

Abstract

Purpose

This study examines the research landscape of Lean Six-Sigma (LSS) applications in hospitals for the period of the last decade (2011–2020) to derive answers to the research questions RQ 1: What are the current publication trends for the application of LSS in hospitals concerning document type, Journal (Source), active authors and country-wise publications and their comparison in the two most reputed scientific databases, i.e. Scopus and Web of Science (WoS), RQ2: What are the clusters based on the authors and keywords? RQ3: What are the research trends and author's productivity in LSS applications in Hospitals? RQ4: What are the future research areas?

Design/methodology/approach

This article compares these two databases (Scopus and WoS) based on publication pattern, document type, active authors and co-citation analysis. This article analyzes the core sources, author's productivity, globally cited articles, word growth analysis, thematic map and world collaboration map on the WoS and Scopus dataset. The software used are Vosviewer, Biblioshiny (R Package for Bibliometric) and M.S. Excel.

Findings

The application of LSS in hospitals is a niche theme. In the WoS database International Journal of Lean Six-Sigma and in Scopus database International Journal of Health Care Quality Assurance are the most relevant sources publishing research articles in this field. The USA has the highest scientific production in this field. Among the authors, Antony J is the most active author in this area, with the highest contribution over the years.

Originality/value

This study fills the literature gap by mapping the field of LSS in hospitals.

Abstract

This paper situates geopolitical economy in light of a broader rethinking of the history of capitalism and international power. It discusses why the ideas of British and American hegemony are problematic. Specifically, it argues that categorizing these powers as hegemonic leaves out a more complex history that theories of hegemony have excluded, and cannot include, else the concept of hegemony would collapse. Finally, I suggest geopolitical economy may be a starting point for writing a new history of capitalism and world order.

Abstract

Purpose

This paper, which builds on the findings of WHO's Report on Mental Health and Development, aims to highlight the health, social, economic, and human rights effects of unaddressed mental disorders in low and middle income countries (LMICs) and to propose effective strategies to address mental disorders and their impacts as part of an overall development strategy.

Design/methodology/approach

The paper first reviews the findings of relevant research on mental disorders and poverty and then proposes solutions that can be adopted by countries to promote development.

Findings

This evidence of strong links between poverty and mental disorder supports the argument that mental disorders should be an important concern for development strategies. Mental disorders have diverse and far‐reaching social impacts, including homelessness, higher rates of imprisonment, poor educational opportunities and outcomes, lack of employment and reduced income. Targeted poverty alleviation programmes are needed to break the cycle between mental illness and poverty. These must include measures specifically addressing the needs of people with mental health conditions, such as the provision of accessible and effective services and support, facilitation of education, employment opportunities and housing, and enforcement of human rights protection.

Originality/value

The paper highlights that four out of every five people suffering from mental disorders are living in LMICs. Many LMICs have identified mental health as an important issue, yet lack the finances and technical expertise to address the problem. Having mental health on the agenda of development organizations will be a critical step for overcoming the negative development consequences of mental disorders.

Abstract

Purpose

The purpose of this paper is to examine and introduce comprehensive insights into the field of Lean Six Sigma (LSS) by reviewing the existing literature and identifying the research gap. The state of LSS research is assessed by critically examining the field, along with a number of dimensions, including time horizon, year, journal and publisher, university, country, author, geographic analysis, research design, research affairs, research methods, tools/techniques used, focus industries, major research area, benefits gained by LSS, critical success factors and barriers of LSS implementation.

Design/methodology/approach

This paper is based on a systematic literature review of 190 articles containing the word LSS in their title, which are published in a well-known database, such as Elsevier ScienceDirect, Taylor and Francis, Emerald Full Text, Springer Link, Wiley InterScience and Inderscience from January 2000 to September 2016.

Findings

This analysis reveals 15 significant dimensions to identify the state of LSS research. Authors find a noticeable rise in the attention of LSS research in the available literature. Major findings show that, the empirical research holds greater credibility. Statistics prove that the case study method scores the highest among all the research methods used in the discipline. The largest number of studies have investigated research issues related to implementation and process of LSS. The LSS uses a wide range of tools/techniques/methodologies: the choice of tools is situation-specific. Manufacturing and health-care sectors have been the focus of LSS research, but LSS has also been adopted by other types of industries. The organizations following LSS have improved bottom-line results, improved company profitability and growth and enhanced customer satisfaction. In general the research is more interpretive in nature; there is still a lack of standard in the LSS implementation framework.

Research limitations/implications

This study is limited to reviewing those articles which contain the word LSS appeared in the title.

Originality/value

This study will help understand the current state of research on LSS, various trends in the field, its applicability and future prospects of investigation in the field.

Abstract

Purpose

The purpose of this paper is to develop the balance score card (BSC) approach based Lean Six Sigma (LSS) performance measurement system and investigate the critical measures currently practiced by Indian manufacturing organizations.

Design/methodology/approach

This study offers insights of LSS performance measurement from manufacturing industry. Initially, the BSC-based framework is developed to recognize the adoption of LSS performance measures. Then, the framework is applied to nine Indian manufacturing organizations to assess the LSS performance measure practice.

Findings

The BSC-based framework of LSS performance evaluation for manufacturing industry is formulated. Then, adoption of these LSS performance measures is investigated with nine Indian manufacturing organizations. The result indicates significant variability in terms of practicing level of LSS measures. However, the majority of organizations are more sensitive to the customer perspectives.

Practical implications

This study reveals a background as to why the performance measurement is required for the success of LSS and for providing practical guidelines for designing performance metrics. The framework interrelates and captures various LSS perspectives and indicator measures, and furnishes a comprehensive outlook of the organization for strategic analysis. This study provides BSC-based template for performing the benchmarking study. This analysis may serve as a reference point for manufacturing organization to determine their system weaknesses, and assist them to concentrate on their most vital and suitable criteria and objectives. However, the analysis contributes to the knowledge on LSS performance measurement system and catches differences in theory and practice, paving the approach to newer research.

Originality/value

This study renders an industry-oriented LSS performance measurement practical approach and suggests the easily adopted vital performance measures for different manufacturing organizations.

Case overview

The case is based on Titan Company Limited (Titan), one of India’s profitable diversified companies. Set in April 2020, the case presents the evolution of Titan’s growth strategy in the last three decades. The company had grown by continuously exploring adjacent categories in the personal lifestyle space. The case asks whether the strategy that has guided Titan for the past three decades would continue to provide growth. What changes, if any, should be made by C.K. Venkataraman—the new CEO who had taken charge a few months back in October 2019—and his team?

The case describes Titan’s evolution from 1987 to 2020. ‘Winning times’, the first section of the case, describes Titan’s early choices in the watches business that helped the company achieve market dominance and its successive choices to expand the scope of watches businesses by entering new adjacencies. The section also details the evolution of Titan’s design, manufacturing, marketing and retailing capabilities in early years. ‘Looking for another gem’ describes Titan’s venture into the jewellery business – the failure of its early attempts to export and its pivot to domestic market and the successful turnaround of the business. ‘On the fast track to growth’ deals with Titan’s accessories business. The section ‘Eyeing new businesses’ describes Titan’s foray into prescription eyewear and precision engineering businesses and the company’s performance in these businesses. ‘A new identity’ details Titan’s adoption of a distinct corporate identity in 2013. ‘New businesses’ provides information on Titan’s recent foray into fragrances and sarees business. The case ends with the section ‘Years ahead’ which asks what changes, if any, should be made by the leadership team.

Expected learning outcomes:

Upon completion of the case study discussion, participants will be able to: understand the concept of the ‘core competence’ and the three tests of core competence; how core competencies evolve in an organization over time; diversification (growth) strategy based on core competencies and adjacencies; and key managerial choices and organizational processes required to ensure effectiveness of diversification strategy based on core competencies.

Abstract

Purpose

The purpose of this paper is to identify, analyze and orient the enablers of Six Sigma to enhance supplier capability for an Indian manufacturing supply chain (SC).

Design/methodology/approach

In total, nine enablers of Six Sigma were identified through an extensive literature review and discussion held with managers/senior managers in different Indian manufacturing companies. The interpretative structural modeling (ISM) approach is applied to the Indian auto ancillary company for developing and analyzing the structural framework of enablers to enhance the supplier capability.

Findings

The enablers such as top management commitment and leadership, supply chain management, standardization, training and education, human resource management and project selection and execution methodology of Six Sigma related to supplier capability have emerged as the prominent enablers, which are driving force in the system for the Indian manufacturing SC.

Research limitations/implications

This study is restricted to only one Indian manufacturing company. Therefore, the outcomes of the study should not be generalized. Further studies may be carried out for several Indian manufacturing industries to get a more comprehensive implementation approach, their validity and their variation across the different industries.

Practical implications

The simplicity and clarity of the proposed structural framework of Six Sigma helps in the identification and orientation of enablers for the successful implementation of Six Sigma in the SC. The proposed structural framework can be applied to different manufacturing SCs by allowing managers to structure the enablers considering their unique implementation constraints, which can reflect their priority considerations.

Originality/value

The study goes beyond the conceptual discussion of supplier capability issues. The supplier capability cannot be seen as a standalone approach irrespective of the constraints from the supplier domain as it is in synchronization with the entire SC performance. The enablers and their orientation with respect to the SC are providing a unique contribution toward supplier management planning. The outcomes from the proposed structural framework are used for developing action plans for organization “A” or other organizations to build suitable supplier capability in the SC.

Abstract

Purpose

Agile new product development (ANPD) attracts researchers and practitioners by its ability to rapidly reconfigure products and related processes to meet the needs of emerging markets. To increase ANPD adoption, this study aims to identify ANPD enablers (ANPDEs) and create a structural framework that practitioners can use as a quick reference.

Design/methodology/approach

Initially, a comprehensive literature review is conducted to identify ANPDEs, and a structural framework is developed in consultation with an expert panel using a hybrid robust best–worst method interpretive structural modeling (ISM). During the ISM process, the interactions between the ANPDEs are investigated. The ISM result is used as input for fuzzy Matrice d’Impacts croises-multiplication appliqúean classment means cross-impact matrix multiplication applied to classification (MICMAC) analysis to investigate enablers that are both strong drivers and highly dependent.

Findings

The study’s findings show that four ANPDEs are in the low-intensity cluster and thus are excluded during the structural frame development. ISM output shows that “Strong commitment to NPD/top management support,” “Availability of resources,” “Supplier commitment/capability” and “Systematic project planning” are the important ANPDEs. Based on their driving and dependence power, the clusters formed during the fuzzy MICMAC approach show that 16 ANPDEs appear in the dependent zone, one ANPDE in the linkage zone and 14 ANPDEs in the driving zone.

Practical implications

This research has intense functional consequences for researchers and practitioners within the industry. Industry professionals require a conservative focus on the established ANPDEs during ANPD adoption. Management has to carefully prepare a course of action to avoid any flop during ANPD adoption.

Originality/value

The framework established is a one-of-a-kind study that provides an integrated impression of important ANPDEs. The authors hope that the suggested structural framework will serve as a blueprint for scholars working in the ANPD domain and will aid in its adoption.
