Abstract

Purpose

This paper aims to provide new and valuable insights for organizations that have decided to implement Lean Six Sigma (LSS) as a strategy for continuous improvement in search of business excellence. This objective is achieved through statistically modeling the causal relationships between the critical success factors (CSFs) of LSS for a successful deployment of this strategy.

Design/methodology/approach

A statistically validated questionnaire was used to collect information from LSS practitioners in manufacturing industries located on Mexico’s northern border. Some hypotheses for relationships between LSS CSFs are developed theoretically first and empirically tested later using the structural equation modeling technique.

Findings

Proposed relationships between LSS CSFs have been demonstrated to be statistically significant, making clear that this implementation should always begin with a strong and decided participation and commitment of top management. Later, other CSFs must be activated and put into operation in a specified order to increase the probability of a successful implementation reflected in well-executed continuous improvement projects and achieving the expected benefits.

Originality/value

This paper proposes a structural model which has been statistically validated with information directly collected from skilled practitioners who have developed continuous improvement projects using the LSS methodology. Further, some relationships between LSS CSFs that, to the best of the author’s knowledge, had not been demonstrated empirically are now explored and verified in our work.

Abstract

Purpose

The objective of this article is to identify the relationships between the enablers in the implementation of Green Lean Six Sigma (GLSS) in the Mexican manufacturing industry (MMI).

Design/methodology/approach

To create the survey instrument, the authors did an extensive literature research, which they then applied in the MMI to find the relationships between enablers and their impact on the positive effects of implementing GLSS projects. Using exploratory and confirmatory factor analyses (EFA and CFA), the data were empirically and statistically corroborated. Furthermore, the authors validated the hypotheses that support the research using the structural equation modeling (SEM) approach in SPSS Amos.

Findings

The findings reveal that leadership has a positive impact on social and economic benefits (EcB), as well as an indirect impact on the environmental benefits (EB) of GLSS projects, with organizational involvement (OI) and performance measurement (PM) functioning as mediators.

Practical implications

This study represents an empirical reference for practitioners and researchers pursuing high-quality, low-cost, environmentally and socially sustainable products or processes through the implementation of GLSS projects in the manufacturing industry.

Originality/value

This study provides a statistically validated model using the SEM technique to represent the relationships between GLSS enablers in the MMI.

Abstract

Purpose

This paper aims to identify the relationships among critical success factors (CSFs) for lean six sigma (LSS) implementation in higher education institutions (HEIs).

Design/methodology/approach

An extensive literature review was conducted to design the survey instrument, which the authors later administered in Mexican public HEIs to identify the existing relationships among the CSFs and their impact on the benefits obtained from implementing LSS projects. The data were empirically and statistically validated using exploratory and confirmatory factor analysis. Additionally, the authors applied the structural equation modeling (SEM) technique on SPSS Amos to validate the nine hypotheses supporting the research.

Findings

The results suggest that the success of LSS projects in HEIs is highly bound to a serious commitment from top management and several interrelated factors.

Research limitations/implications

The main limitations of the study are that the research is cross-sectional in nature and regional in focus. Namely, the data used to validate the structural model were gathered from a small representative subset of the study population – i.e. Mexican public HEIs – and at a specific point in time.

Practical implications

The results reported here represent a reference framework for HEIs worldwide that wish to continuously improve their processes through LSS improvement projects.

Originality/value

This study proposes a statistically validated model using the SEM technique that depicts the relationships among LSS CSFs in HEIs.

Abstract

Purpose

The objective of the study is to design and validate an instrument that allows organizations to assess their status regarding the adoption of the critical success factors (CSFs) that enable lean six sigma (LSS) implementation in order to achieve the expected benefits.

Design/methodology/approach

An extensive literature review was conducted to define the LSS CSFs that have to be considered for the development of the questionnaire that would later be applied across all manufacturing companies on the Northern Mexican border. Once the database was built, a statistical verification of the assumptions required for factor analysis took place. Finally, the due construct validation was carried out to verify whether the proposed instrument measured reliably what it is intended to.

Findings

A questionnaire measuring nine CSFs, as well as the benefits associated with the implementation of LSS, was designed and validated through 61 items.

Research limitations/implications

The main limitations of this study are that the research is cross-sectional and that the study was carried out taking as a reference only exporting manufacturing companies located in the border area between Mexico and the United States.

Practical implications

The validated instrument is expected to serve as a useful tool for companies interested in the implementation of LSS.

Originality/value

This study introduces a validated tool for the analysis of LSS CSFs while providing evidence of construct validity and the solid structure of the factors.

Abstract

Purpose

The purpose of this paper is to extend the understanding of Six Sigma (SS) and the underlying dimensions of its critical success factors (CSF) via an analysis of the effects of top management support (TMS), implementation strategy (IS), and collaborative team (CT) on project performance (PP) in Mexican manufacturing companies.

Design/methodology/approach

Based on a SS literature review, a survey was conducted to capture practitioners’ viewpoints about CSFs for SS implementation and their impact on performance in manufacturing companies. A factor analysis and structural equation modeling were conducted in order to identify and analyze causal relationships.

Findings

The results suggest that CSFs grouped in the constructs TMS, IS, and CT have a positive impact on PP as measured by cost reduction, variation reduction, and quality improvement.

Research limitations/implications

Although the empirical data collected supported the proposed model, results might differ among organizations in different countries. In addition, the study did not analyze a unique performance metric; instead, general PP dimensions were used.

Practical implications

Boosting the TMS, IS, and CT enhances positive PP of SS in manufacturing companies.

Originality/value

IS as a construct has not been studied exhaustively; this work contributes to a better understanding of it and its impact on PP. Additionally, studies of SS in Latin America are limited, so this study gives a complementary vision to practitioners and researchers about it.

Abstract

As the First Lady, Michelle Obama stated that she had a number of priorities but that the first year would be mainly about supporting her two girls in their transitions to their new life in the White House. Her choice to be mom-in-chief drew unusually intense and rather puzzling, scrutiny. The chapter briefly discusses the range of reactions along the political spectrum as well as African-American feminists’ analyses of the stereotypes of Black women underlying those reactions. This analysis engages the debates from a different perspective. First, the chapter addresses the under-theorizing of the racialized gender norms embedded in the symbolism of the White House and the role of First Lady. It challenges the presumption of traditional notions of true womanhood and the incorrect conclusion that mothering would preclude public engagement.

Second and most importantly, this chapter argues that there are fundamental misunderstandings of what mothering meant for Michelle Obama as African-American woman. Cultural traditions and socio-historical conditions have led Black women, both relatives and non-kin, to form mothering relationships with others’ children and to appreciate the interdependence of “nurturing” one's own children, other children, and entire communities. Those practitioners whose nurturing activities encompassed commitment and contributions to the collectivity were referred to as community othermothering. Using primary sources, this chapter examines in detail Michelle Obama's socialization for and her practice of community othermothering in her role as First Lady. Attention is focused on her transformation of White House events by extending hospitality to more within Washington, DC, and the nation, plus broadening young people's exposure to inspiration, opportunities, and support for setting and accomplishing their dreams. Similarly, the concept of community othermothering is also used to explain Michelle Obama’s reinterpretation of the traditional First Lady's special project into the ambitious “Let's Move” initiative to end childhood obesity within a generation. The othermothering values and endeavors have helped establish the White House as “the People's House.”
