Lean Six Sigma in higher education institutions

An empirical study into the use of 7 quality control tools in higher education institutions (HEIs)

Purpose

The main purpose of this study is to revisit Ishikawa's statement: “95% of problems in processes can be accomplished using the original 7 Quality Control (QC) tools”. The paper critically investigates the validity of this statement in higher education institutions (HEIs). It involves analysis of the usage of the 7 QC tools and identifying the barriers, benefits, challenges and critical success factors (CSFs) for the application of the 7 QC tools in a HEI setting.

Design/methodology/approach

An online survey instrument was developed, and as this is a global study, survey participants were contacted via social networks such as LinkedIn. Target respondents were HEIs educators or professionals who are knowledgeable about the 7 QC tools promulgated by Dr Ishikawa. Professionals who work in administrative sectors, such as libraries, information technology and human resources were included in the study. A number of academics who teach the 7 basic tools of QC were also included in the study. The survey link was sent to over 200 educators and professionals and 76 complete responses were obtained.

Findings

The primary finding of this study shows that the diffusion of seven QC tools is not widespread in the context of HEIs. Less than 8% of the respondents believe that more than 90% of process problems can be solved by applying the 7 QC tools. These numbers show that modern-quality problems may need more than the 7 basic QC basic tools and there may be a need to revisit the role and contribution of these tools to solve problems in the higher education sector. Tools such as Pareto chart and cause and effect diagram have been widely used in the context of HEIs. The most important barriers highlighted are related to the lack of knowledge about the benefits and about how and when to apply these tools. Among the challenges are the “lack of knowledge of the tools and their applications” and “lack of training in the use of the tools”. The main benefits mentioned by the respondents were “the identification of areas for improvement, problem definition, measurement, and analysis”. According to this study, the most important factors critical for the success of the initiative were “management support”, “widespread training” and “having a continuous improvement program in place”.

Research limitations/implications

The exploratory study provides an initial understanding about the 7 QC tools application in HEIs, and their benefits, challenges and critical success factors, which can act as guidelines for implementation in HEIs. Surveys alone cannot provide deeper insights into the status of the application of 7 QC tools in HEIs, and therefore qualitative studies in the form of semi-structured interviews should be carried out in the future.

Originality/value

This article contributes with an exploratory empirical study on the extent of the use of 7 QC tools in the university processes. The authors claim that this is the first empirical study looking into the use of the 7 QC tools in the university sector.

The moderating role of Lean Six Sigma practices on quality management practices and quality performance in medical device manufacturing industry

Purpose

The purpose of this paper is to explore the moderating role of Lean Six Sigma (LSS) practices in explaining the relationship between quality management practices (QMPs) and quality performance.

Design/methodology/approach

Partial least square-based structural equation modeling (PLS-SEM) was used to empirically examine the moderating effect of LSS practices on QMPs and quality performance in Malaysian medical device manufacturing companies.

Findings

Findings revealed that both QMPs and LSS practices have a significant and positive effect on quality performance. Furthermore, LSS practices served as a substitute for moderating the positive relationship between QMPs and quality performance in such a way that the relationship becomes weaker as LSS practices increase.

Originality/value

LSS is acknowledged as the most well-known hybrid methodology; however, due to its relative newness, it has not been studied in great detail. Unlike previous studies, this paper argued that Lean and Six Sigma practices are distinct from its predecessor TQM practices; moreover, both Lean and Six Sigma practices do not need to substitute QM/TQM practices instead of complimenting the QMPs. In addition, this study adds to the growing body of QM literature by empirically examine the effect of LSS practices in moderating the relationship between QMPs and quality performance.

The effect of supply chain agility and lean practices on operational performance: a resource-based view and dynamic capabilities perspective

Purpose

In today's global economy, developing supply chain agility (SCA) and lean practices (LP) as resource-based view and dynamic capabilities are essential for firms to sustain their competitive advantage (CA) and enhance their operational performance (OP). The purpose of this paper is to develop and empirically test a framework to investigate how CA is achieved through SCA and LP and how these, in turn, can enhance a firm's OP.

Design/methodology/approach

For data collection, the authors adopted the survey method using self-administered questionnaires. Two-source survey data were collected in two rounds (separated by a two-month lag time) from supply chain managers, operational managers and general managers. The purpose of collecting data in two rounds was to reduce common-method bias. Likert scale (1–5) was used in the questionnaire. Smart PLS 3 and SPSS 23 were used for the data analysis purpose.

Findings

SCA was found to directly and positively affect OP. LP also positively affected OP. In addition, CA fully mediated the relationship between SCA, LP and OP.

Practical implications

This study encourages the managers of manufacturing firms to adapt LP and their supply chains (SCs) to become agile and leverage the advantages of their implementation to improve their OP and succeed in the market.

Originality/value

This study is one of the first to investigate the effect of SCA and LP on OP. Furthermore, the first study examines CA's mediating impact on the relationship between SCA, LP and OP.

Evaluation of Flexible Strategies to Manage the COVID-19 Pandemic in the Education Sector

COVID-19 has had a substantial impact on almost every field including the education sector. Due to the requirements for social distancing, the pandemic has provided an impetus for change in the education sector; technology-based sustainable education platforms not experienced previously have become essential. This research aims to propose flexible strategies to mitigate challenges of COVID-19 pandemic in the education sector of an emerging economy: Bangladesh. A total of 16 challenges and 19 flexible strategies were identified based on stakeholders’ inputs and literature review. To evaluate the flexible strategies, a methodology based on Pareto analysis and a revised rough-decision making trial and evaluation laboratory (rough-DEMATEL) method is proposed. Findings reveal that in the context of the COVID-19 pandemic, ‘Maintain social distancing and health protocol,’ ‘Enhance the communication and collaboration among students and teachers,’ ‘Financial incentives from government,’ ‘Utilize modern technologies for digitizing the entire education system,’ and ‘Know how to engage students in an online environment’ are the vital strategies that must be implemented if education continues through E-learning. Because the current pandemic situation is a new experience for many individuals around the world, this study helps to recognize the challenges and to propose effective strategies to solve these challenges so that education does not become stagnant.

Lean Six Sigma in consumer banking – an empirical inquiry

Purpose

The evolution of Lean Six Sigma (LSS) within the operations management theory has enjoyed significant success in both manufacturing and services. Though the applicability of LSS is evident in the services sector through various publications, academic research on the use of LSS in the Banking and Financial Services (BFS) is limited, and hence deserves greater attention. The purpose of this paper is to illustrate the application of LSS in consumer banking in real-time setting.

Design/methodology/approach

A case study method is used to study the application of LSS in two consumer banks with stage 1 featuring identification of appropriate consumer banks where LSS projects could be undertaken, and suitable LSS readiness assessment was performed. In stage 2, LSS project opportunities were identified in the select banks through stakeholder engagement. Finally, in stage 3, LSS projects were executed for process improvements in a real-time setting.

Findings

The case studies provide evidence of the successful application of LSS in consumer banking and the associated multiple benefits. The extent of applicability and appropriate managerial implications in project management context are elaborated. An LSS project selection criterion is recommended as a part of the study. Further, the study explains five important managerial implications in BFS context, with an outlook for future research.

Research limitations/implications

Practitioner research shows that BFS organizations have changed their ways of working by adapting LSS over the last decade. However, the academic research concerning the applicability of LSS in BFS is apparently limited, and none of these are specific to “consumer banking.” This study serves as a strong foundation for future research in this area, which is at its nascence and upcoming in the researchers’ community. However, strong generalizations should not be made as this study is limited to two cases.

Practical implications

Since the cases are executed in the real-time setup of consumer banks, the paper has several practical implications. First, the paper confirms the applicability of LSS in consumer banking and concludes that LSS project management is merely a sub-set of LSS deployment. Second, LSS needs to be understood using a “systems thinking” perspective in order to move away from a narrow project-only approach. An LSS project selection criterion is recommended as a part of the study, which could serve as a managerial resource. Other managerial implications include effective management of stakeholders and change leadership as essential elements of LSS project management in banks.

Originality/value

LSS has been successful in the past few decades in the manufacturing and service sectors. However, its application in BFS is limited. This study illustrates the applicability of LSS in consumer banks, which deals with high volumes of data, customer bases and associated financial transactions.

V. Impacts of Lean Six Sigma on improving a higher education system: a case study

Purpose

The purpose of this paper is to demonstrate the applicability and impact of Lean Six Sigma (LSS), a contemporary quality excellence methodology, for improving education system in a reputed University in Iran.

Design/methodology/approach

The paper follows a case study approach illustrating how theory has been put into practice, explaining how to implement the LSS define-measure-analyze-improve-control framework in a field-setting in a higher education institution (HEI), and to highlight the subsequent challenges occurred and lessons learned during the implementation.

Findings

The key finding from the study is the confirmation of LSS applicability in education systems. The goals of the LSS team were to baseline student satisfaction levels and improve the overall rating by 10 percent; to decrease student advising wait times by 15 percent; and increase enrollment by 5 percent. The application of the LSS methodology has delivered promising results to improve the education system of the University by achieving the set goals. Further, the implementation of LSS has demonstrated student-facing benefits of improved quality on the education system.

Research limitations/implications

LSS implementation in HEIs is relatively a new topic for research. Hence, this case study adds to the body of knowledge with directions to progress future research in this area.

Practical implications

The outputs of the case study have provided greater stimulus within the facilities for wider full-blown deployment of LSS as a strategic resource for problem solving. Additionally, this case study sets the foundation for many other future projects, and to trigger interest among the HEIs in their journeys for quality excellence.

Social implications

Higher education sector being a socially responsible field of service, LSS offers continuous improvement benefits, highlighted as part of this paper.

Originality/value

The applicability of LSS in HEIs is relatively an upcoming research area with immense potential and value. This paper would serve as a valuable means for both researchers and practitioners working in HEIs, in terms of understanding the systematic application of the LSS methodology, and implications in a real-world situation.

Lean thinking for education: development and validation of an instrument

Purpose

The purpose of this paper is to respond to the increasing demands that education currently faces and develop a structured approach for the implementation of lean thinking (LT) in primary and secondary education (P&SE) and empirically validated it.

Design/methodology/approach

An extended literature review was conducted of studies on LT in education, service and manufacturing, in which a preliminary list was formed of LT dimensions, which were subsequently reviewed by a focus group. An instrument was generated, which was distributed to 1,400 education professionals, and 394 replies were received. The measures were tested for validity and reliability. After the first round of analyses, measures were tested further to strengthen the proposed instrument.

Findings

The findings confirmed that the instrument developed is both valid and reliable and that the proposed measures consist actual dimensions of LT in P&SE. A number of success factors that would be required for LT initiatives to be implemented effectively within the P&SE context in a holistic perspective were revealed.

Practical implications

Although a number of studies have been developed on LT in the manufacturing or service sector, its implementation in education and particularly in P&SE remains scant. The instrument developed provides sufficient knowledge of which are the most important dimensions to consider when pondering LT in education.

Originality/value

While LT has been the subject of previous research in education, this study represented the first look at lean in P&SE and was the first of its kind to develop and validate in a real environment a lean implementation instrument for use in educational institutions. Researchers and practitioners can use the proposed instrument to build models of facilitating practices to improve performance while contributing to economic growth and enhancing social empowerment.

An empirical investigation of implementing Lean Six Sigma in Higher Education Institutions

Purpose

The purpose of this paper is to empirically investigate the applicability and implementation of Lean Six Sigma (LSS) in Higher Education Institutions (HEIs). LSS is considered as the most recent service quality practice which has proved its success in manufacturing and service sectors. Though there is plenty of literature available with regard to the application and benefits of LSS in services sectors (like Banking, healthcare, information technology sectors, etc.), there is apparently no evidence in the literature about the implementation of LSS in HEIs.

Design/methodology/approach

A five-phased approach is followed. A multiple case-study method is used in this paper to explore this implementation of LSS in two select international University colleges. LSS toolkit comprising of define-measure-analyze-improve-control phases is used for the execution of the projects. Featuring student teams in LSS project management adds novelty to the approach.

Findings

The paper empirically validates the application of LSS in HEIs. Further, it highlights the practical challenges and benefits of LSS in the HEI setup. An in-depth empirical analysis of LSS toolkit application, LSS change management and using student teams in LSS project management are the highlights of this paper. The paper concludes that LSS is applicable and could provide positive benefits to HEIs.

Research limitations/implications

LSS application in HEIs is perhaps a new research area, which is at its nascence and upcoming in the researchers’ community. Hence, this paper would serve as a platform and provide directions for future scholars to ponder on the subject.

Practical implications

Since the cases are executed in the real-time setup of HEIs, the paper has several practical implications. First, the academia and practitioners’ collaboration in executing projects adds novelty. Second, the involvement of student teams from project selection to execution brings in practical perspectives alongside the academic education. Several other key lessons learned and benefits of LSS in HEI setup are presented as part of the paper.

Originality/value

LSS has been successful in the past few decades in the manufacturing and service sectors. However, its application in HEIs was very nascent, and few researchers even doubted its relevancy of application in HEIs. This study illustrates its importance and application to the higher education sector which is a highly responsible area of the service sector, for imbibing quality excellence, serving as an excellent resource for researchers and higher education professionals.

A conceptual Lean Six Sigma framework for quality excellence in higher education institutions

Purpose

The purpose of this paper is to present the potent application of Lean Six Sigma (LSS) in higher education services and to suggest a conceptual framework of deploying LSS in the higher education institutions (HEIs).

Design/methodology/approach

This paper aims to outline the importance of the quality excellence criterion in general through different constructs from the literature including TQM, Lean, Six Sigma and LSS. The paper further expands on the applicability of LSS in the HEI setting, with an understanding of HEI as comparatively different from the manufacturing sector from where LSS originated. The published literature on LSS and authors’ experience in the field of LSS (as practitioners) were used as sources for devising a conceptual framework for LSS deployment in HEIs.

Findings

The key finding from the study is the confirmation of LSS applicability in HEIs. The study also confirms that LSS is not anyone’s job but a key part of leadership agenda. The six-staged conceptual framework prescribed for the HEIs as part of the paper is the key contribution of this study. The model describes that LSS readiness is the foremost step in the LSS deployment journey in HEIs. The strategic perspectives of aligning the organisational vision for quality excellence need to be achieved by establishing a need for LSS through leadership. Then, developing an LSS deployment strategy becomes the next step. Educating the appropriate stakeholders (students) and team formation becomes the next important steps in the LSS deployment. Once the above steps are implemented in right way, identifying and implementing LSS projects becomes critical. The execution and closure of the LSS projects leads to quality excellence in HEIs.

Research limitations/implications

Since the framework prescribed here is a conceptual framework, it deserved a testing in the real-life context. This leaves an opportunity for future researchers to test and expand on the implications of the model. Though the LSS framework is customised for HEIs, the fundamental factors essential for any change management initiative holds correct for LSS as well, and hence these are not elaborated as part of this paper.

Originality/value

This paper would serve as an excellent resource for both academicians and LSS practitioners in HEIs, for deployment. The framework presented here is the original work contributed by the authors, as the first of its kind in the academic literature relevant to LSS in HEIs.

Lean Six Sigma journey in a UK higher education institute: a case study

Purpose

The purpose of this paper is to explore the fundamental challenges and critical success factors in the development of a Lean Six Sigma (LSS) initiative within a UK higher education institute (HEI). The paper also illustrates examples of the types of projects completed and share some of the key lessons learned as part of the LSS journey.

Design/methodology/approach

The authors have initially carried out an extensive literature review on the application of LSS in higher education to understand the existing body of work carried out by other scholars in the field. This is followed by presenting a case study explaining how a HEI in the UK has embarked on its LSS journey as a process excellence methodology to improve the efficiency and effectiveness of core and supporting business processes.

Findings

There has been a clear lack of support and commitment from senior management in the sustainability of LSS within the case study organization. There was a general lack of understanding of the benefits of LSS in the higher education context and there is a lack of knowledge on the use of LSS tools for tackling process efficiency and effectiveness problems across the case study organization. Although a number of LSS projects were executed across finance, administrative, and human resources, as well as IT and library services, no projects were carried out for improving academic processes such as teaching effectiveness.

Research limitations/implications

As the case study is limited to one higher education institution (HEI), the findings of the study cannot be broadly generalized. Moreover, the paper does not report the findings of any strategic projects as most projects were carried out at the operational level.

Originality/value

This is possibly one of the first studies reporting project examples of LSS in a HEI. The results of the study can also be used to benchmark with similar studies in other HEIs to understand the impact of certain management practices of LSS.

Applying lean thinking in an educational institute – an action research

Purpose

Lean thinking (LT) has been implemented in various manufacturing and service sectors. But, only a few published research articles have developed a framework describing the procedure for implementing LT in an educational institute. The purpose of this paper is to develop and demonstrate a framework that can provide a structured procedure for the implementation of LT in an educational institute.

Design/methodology/approach

Various LT tools and techniques applicable in educational institute were identified by reviewing the relevant literature. By adopting an action research methodology (ARM) for a time period of 28 months, the processes in a case institute were studied; wastes in the process were identified and various solutions were proposed and implemented.

Findings

A comparison of the performance measures before (Batch 1) and after (Batch 2) implementation of solutions provided interesting insights into the effectiveness of LT. In both the batches, absenteeism in the class was found to increase across the terms. But the magnitude of increase was lesser in Batch 2. Results also showed that the number of unfilled seats (poor utilization) in an elective course in the second year of the program drastically reduced in Batch 2. Finally, a framework that can guide LT implementation in educational institutes was proposed.

Research limitations/implications

The current study describes only the initial stages of implementation in an educational institute. Hence, some of the benefits discussed are expected in the long run which can be assessed by carrying out a longitudinal study. Future study can attempt to empirically validate the proposed framework in multiple educational institutes and theoretically explain the reasons behind the results obtained.

Practical implications

ARM can be used as a tool by practitioners to study the behavioral aspects of employees of educational institutes toward LT implementation. The proposed framework and its demonstration can assist employees in educational institutes to implement LT. Positive results obtained in this study can further motivate the educational institutes to consider LT as a potential tool for improving the processes.

Originality/value

This is the first study to develop and validate a framework for structured implementation of LT in the processes of an educational institute. The study is also unique in empirically capturing the impact of LT implementation of an educational institute by analyzing the archived data.

Constructs of quality in higher education services

Purpose

The purpose of this paper is to present various quality constructs, their application, success and shortcomings, in higher education (HE) services.

Design/methodology/approach

This paper aims at reviewing the quality constructs in higher education services through a general review. The paper is organised to highlight different quality practices which higher education institutions have followed from 1990s till date. The paper is scoped to discuss about total quality management (TQM), Kaizen, Six Sigma, Lean and Lean Six Sigma (LSS) comparing their value addition and shortcoming in imbibing quality into the higher education. Publications indexed in Scopus database are considered for the review. The focus of the search in the selected publications was to identify the success and shortcomings of various quality constructs in HE services.

Findings

The requirement for a quality construct in higher education industry is an important finding of the paper. Alongside this, the reasons behind the shortcoming of quality practices used in higher education system were highlighted. The findings include the opportunities for future research for imbibing quality culture in HE.

Research limitations/implications

The literature discussed in the part of the paper is restricted to TQM, Kaizen, Six Sigma, Lean and LSS. Though the usage of such quality practices in HE originated in 1990s, there is no one robust sustainable practice till date, which proved to be a pacesetter. This paper validates this assertion, which helps both academicians and practitioners with a new perspective.

Originality/value

This paper would serve as an excellent resource for both academicians and practitioners to understand the history of quality which contributed to the improvement in HE services, and how the quality excellence has evolved over the years. The paper concludes with a discussion on opportunities for future research to develop quality frameworks for HE services.
