Is lean service promising? A socio-technical perspective

Lean service: a contingency perspective

Many firms launch consolidated lean initiatives across all their service units, but because services differ, mandated lean practices may have a poor fit with the receiving unit. Whereas plenty of research has investigated the fit of lean implementation at the service industry level, this is the first to delineate how standard lean service practices fit different service types. Taking a contingency theory perspective, we study a leading European utility company comprising distinct service types. Using purposeful sampling, we interview 36 employees from 15 different teams representing three different service types – professional services, service factories and service shops – and 11 employees from the headquarters who are supporting these units in their lean transformation journeys. We also collect secondary data, including lean programme documentation and audit data. We find that one size does not fit all for lean service; there are important nuances to the relevance of standard lean service practices across different service types. Ten propositions are put forward suggesting how standard lean practices need to be adapted to fit the context of different service types. The findings reject the idea that all service units can progress along the same trajectory in lean service programmes. This paper informs managers how lean service programmes can be tailored to increase the fit with different service types.

Managing inpatient bed setup: an action-research approach using lean technical practices and lean social practices

PURPOSE

This article aims to introduce a guide to improving hospital bed setup by combining lean technical practices (LTPs), such as kaizen and value stream mapping (VSM) and lean social practices (LSPs), such as employee empowerment.

DESIGN/METHODOLOGY/APPROACH

Action research approach was employed to analyze the process of reconfiguration of bed setup management in a Brazilian public hospital.

FINDINGS

The study introduces three contributions: (1) presents the use of VSM focused specifically on bed setup, while the current literature presents studies mainly focused on patient flow management, (2) combines the use of LSPs and LTPs in the context of bed management, expanding current studies that are focused either on mathematical models or on social and human aspects of work, (3) introduces a practical guide based on six steps that combine LSPs and LSPs to improve bed setup management.

RESEARCH LIMITATIONS/IMPLICATIONS

The research focused on the analysis of patient beds. Surgical beds, delivery, emergency care and intensive care unit (ICU) were not considered in this study. In addition, the process indicators analyzed after the implementation of the improvements did not contemplate the moment of the COVID-19 pandemic. Finally, this research focused on the implementation of the improvement in the context of only one Brazilian public hospital.

PRACTICAL IMPLICATIONS

The combined use of LSPs and LTPs can generate considerable gains in bed setup efficiency and consequently increase the capacity of a hospital to admit new patients, without the ampliation of the physical space and workforce.

SOCIAL IMPLICATIONS

The improvement of bed setup has an important social character, whereas it can generate important social benefits such as the improvement of the admission service to patients, reducing the waiting time, reducing hospitalization costs and improving the hospital capacity without additional physical resources. All these results are crucial for populations, their countries and regions.

ORIGINALITY/VALUE

While the current literature on bed management is more focused on formal models or pure human and social perspectives, this article brings these two perspectives together in a single, holistic framework. As a result, this article points out that the complex bed management problem can be efficiently solved by combining LSPs and LTPs to present theoretical and practical contributions to the important social problem of hospital bed management.

Becoming a learning organization while enhancing performance: the case of LEGO

Purpose

The purpose of this study is to empirically test how problem-solving lean practices, along with leaders as learning facilitators in an action learning approach, can be transferred from a production context to a knowledge work context for the purpose of becoming a learning organization while enhancing performance. This is important to study because many organizations struggle to enhance efficiency in the short term while still trying to be long-term learning oriented (i.e. learning organization development).

Design/methodology/approach

The authors draw on theory on learning interventions to show how lean practices for problem-solving can foster learning and help an organization to become adaptive. This study’s subject is a non-production department of 100 employees at the LEGO corporation. The authors applied survey results from a natural experiment lasting 18 months between a pre-measurement survey and a post-measurement survey. The results were compared to a control department of 50 employees who were not exposed to the lean practices intervention. The authors’ focus was on the individual level as individuals have different perceptions of lean practices, performance, and learning.

Findings

Using repeated-measures tests, difference-in-difference regressions analyses, and structural equation models, the authors find that a package of contemporary lean practices for problem-solving, along with leaders who function as learning facilitators, significantly improved learning organization dimensions while also enhancing efficiency and quality and that learning organizations positively mediate the relationship between the lean intervention and quality-related performance, while efficiency is directly affected by the lean interventions. Data from LEGO's key performance indicators (KPIs), benefit trackers, on-site observations and more than 40 interviews with managers provided results that were consistent with the survey data. A detailed description of the lean practices implemented is provided to inspire future implementations in non-operations environments and to assist educators.

Research limitations/implications

The authors contribute to the learning literature by showing that a learning-to-learn approach to lean management can serve as an active and deliberate intervention in helping an organization becoming a learning organization as perceived by the individual organizational members. The authors also add to the lean literature by showing how a learning approach to lean, as used by LEGO, can positively affect short-term efficiency and quality and create a foundation for a longer-term competitive advantage (i.e. a learning organization) in a non-production context. By contrast, most of the lean literature streams treat efficiency separately from a learning organization and mainly examine lean in a production context.

Originality/value

The extant literature shows three research streams on lean, learning, and performance. The authors built on these streams by trying to emphasize both learning and efficiency. Prior research has not empirically tested whether and how the application of problem-solving lean practices combined with leaders as learning facilitators helps to create a comprehensive learning organization while enhancing performance in a non-production context.

Beyond efficiency: the role of lean practices and cultures in developing dynamic capabilities microfoundations

Purpose

The purpose of this study is to theorize and test the relationships among lean operations and lean supply chain practices, learning- and innovation-oriented lean cultures and dynamic capabilities (DCs) microfoundations. Further, this study aims to assess the association of DCs microfoundations with process innovation.

Design/methodology/approach

The researchers combine primary data collected from 153 manufacturing firms located in five continents using a survey designed for the purpose of this study with archival data downloaded from the Bureau Van Dijk Orbis database and test the hypothesized relationships using structural equation modelling.

Findings

Results support the contribution of lean operations and lean supply chain practices to the development of DCs microfoundations, which further lead to greater process innovation. Additionally, while a learning-oriented lean culture positively moderates the relationships between both lean operations and lean supply chain practices and DCs microfoundations, an innovation-oriented lean culture only moderates the relationship between lean operations practices and DCs microfoundations.

Practical implications

This study identifies DCs microfoundations as the key mechanisms for firms implementing lean practices to achieve greater levels of process innovation and the important role played by lean cultures. This study provides direction for managers to put in place DCs through lean implementations, enabling their firms to be ready to respond to challenges and opportunities generated by environmental changes.

Originality/value

While previous research has confirmed the positive effects of lean practices on efficiency, the role of lean practices and cultures in developing capabilities for reacting to environmental dynamism has received little attention. This study offers an empirically supported framework that highlights the potential of lean to adapt processes in response to environmental dynamics, thereby extending the lean paradigm beyond the traditional focus on operational efficiency.

Improving operational performance of manufacturing SMEs: the interactive effect of technical and human lean practices

Purpose

Although understanding how different resources are interconnected within firms is important, there are few studies that have focused on this area. This study aims to explore the unique and interactive effects of technical lean practices (TLPs) and human lean practices (TLPs) on the operational performance (OP) of manufacturing SMEs in Yemen, a less developed country (LDC).

Design/methodology/approach

Depending on data collected from 318 manufacturing SMEs in Yemen, the relationships in the proposed model were tested using hierarchical regression analysis via PROCESS Macro V. 3.5 in SPSS.

Findings

The results show that both TLPs and HLPs have unique effects on OP of SMEs. More importantly, both TLPs and HLPs have synergistic effects on OP.

Practical implications

The study would be of interest to Lean practitioners, as the results of this study can be used in firms to put a focus on how TLPs and HLPs have to interact when it comes to the successful implementation of lean manufacturing (LM).

Originality/value

Although research interest in LM is increasing, the interactive effects of TLPs and HLPs remain to be understood. This study provides an initial empirical evidence for performance outcomes from the interaction between TLPs and HLPs of SMEs in LDCs such as Yemen. Most of the previous studies on lean practices have focused on SMEs in developed countries, which may not fully apply to LDCs such as Yemen. This is helpful for SMEs' managers in the context of LDCs to understand how TLPs can further improve OP when interacting with HLPs.

Exploring Lean HRM Practices in the Aerospace Industry

Lean places people at its core, acknowledging their contribution to the company’s growth and the fundamental role human resources management (HRM) practices play in the success and sustainability of Lean transformations. However, the relationship between HRM practices and Lean remains largely unexplored in the literature. The purpose of this work is therefore to investigate the challenges and contributions of HRM practices in a Lean company, and identify those practices that are required for successful and sustainable Lean implementations. Based on a sample of thirty employees (15 production and 15 office workers) of a Canadian aerospace company who participated in our interviews, we performed a qualitative analysis to identify prominent HRM practices. We found seven HRM practices that are of major importance in the context of Lean (i.e., job security, communication, fairness, supervisor/manager support, training, occupational health and safety, and respect). Our findings show that these practices are equally relevant to both production and office workers, and suggest that managers play a decisive role in implementing these practices, and in providing the right environment to effectively promote workforce commitment.

Lean and its impact on sustainability performance in service companies: results from a pilot study

Purpose

The purpose of this empirical research is to understand the application of Lean practices (technical and social) and tools in the service sector, whose implementation is less studied, despite its economic relevance. The study aims to extend previous studies that focused on the relationship between Lean and operational and financial performance, and analyzing the impact on sustainability, encompassing economic, social and environmental perspectives.

Design/methodology/approach

A pilot survey was conducted with Lean experts in European service companies. The authors have utilized various professional contacts on LinkedIn and a satisfactory response rate was obtained for analysis.

Findings

The results of the study showed that there are several motivating factors for the implementation of Lean, the highlights being improving customer satisfaction, efficiency, delivery and cost reduction. The most frequently used Lean tools are related to the identification of improvement opportunities and causes of problems. The pilot survey also made it possible to identify the greater use of technical practices than social practices. The sustainability performance analysis showed that the better performance of service companies is in the economic dimension.

Originality/value

The authors have identified no empirical studies linking Lean and sustainable performance in the service sector. This study bridges this cognitive gap through a pilot study and therefore makes an original contribution to the current literature.

Lean Six Sigma Impact Analysis on Sustainability Using Partial Least Squares Structural Equation Modeling (PLS-SEM): A Literature Review

The Lean Six Sigma (LSS) philosophy and sustainability have become topics of interest since the 1990s; they have generally been analyzed together since 2012. Numerous professionals, managers, and researchers have sought methodologies by which to assess their impact and know their effectiveness within companies. During the past decade, the application of partial least squares structural equation modeling (PLS-SEM) has been widely accepted in various modeling, prediction, or multivariate analyses as a way to measure the impact of LSS on sustainability. This study conducts a literature review to identify the use of PLS-SEM in measuring the impact of LSS on sustainability. A systematic review methodology has been employed, applying five search criteria to three scientific database platforms. This approach has been helpful to identify PLS-SEM as a valuable methodology for measuring the impact of LSS on sustainability. One of the research findings is that LSS practices positively impact 83% of economic indicators, 78% of environmental indicators, and 70% of social indicators. This article creates a theoretical foundation for future research on these issues, outlining research opportunities to generate future studies. It also allows researchers and managers who are interested in improving sustainability indicators to access valuable knowledge regarding what types of LSS tools could be used.

A Conceptual Framework for Implementing Lean Construction in Infrastructure Recovery Projects

Natural hazards can have substantial destructive impacts on the built environment. Providing effective services in disaster areas is heavily reliant on maintaining or replacing infrastructure; thus, post-disaster reconstruction of infrastructure has attracted growing attention. Due to the complex and dynamic nature of infrastructure recovery projects, contractor companies engaged in this work have typically experienced poor performance. Furthermore, from a commercial perspective, the post-disaster reconstruction environment is characterized by fierce competition and market uncertainty, challenging the organizational resilience of companies undertaking this work. One approach for improving contractor performance is the implementation of lean construction, but the literature lacks consensus on its capability to affect organizational resilience. To respond to this problem, a conceptual framework applicable for lean implementation in infrastructure, which explicitly addresses organizational resilience, is required for recovery projects. In parallel, contributing components to effective implementation of lean-recovery and supportive theories for justifying the conceptual framework must be identified. Consequently, this paper proposes a conceptual framework to implement lean practices for the enhancement of organizational resilience. The framework is developed using a systematic research method, wherein 110 research documents were discovered initially, and following processing, 18 relevant documents were identified and analyzed. Through this process, contingency and Transformation-Flow-Value (TFV) theories were identified as an appropriate foundation for a framework to implement lean construction in infrastructure recovery projects.

The influence of soft and hard TQM on quality performance and patient satisfaction in health care: investigating direct and indirect effects

PURPOSE

The present study conceptualizes total quality management (TQM) in terms of soft and hard aspects and examines their effects on quality performance and patient satisfaction. The indirect effects of soft and hard TQM on patient satisfaction through quality performance are also investigated.

DESIGN/METHODOLOGY/APPROACH

A multi-item questionnaire was prepared to gather primary data from a sample of 312 medical employees in private hospitals in Jordan. The measurement model was evaluated for validity and reliability and determined to be acceptable. Structural equation modeling (SEM) was applied to test the research hypotheses.

FINDINGS

The results revealed that soft TQM has a strong positive effect on quality performance and patient satisfaction. Hard TQM was found to positively affect quality performance but to a lesser extent compared to soft TQM. The effect of hard TQM on patient satisfaction, meanwhile, was not significant. Quality performance positively mediated the relationship between TQM - both soft and hard - and patient satisfaction.

ORIGINALITY/VALUE

This study is one of the first to conceptualize TQM in terms of soft and hard aspects in a health care context. It offers valuable insights for managers of private hospitals looking to enhance quality performance and patient satisfaction. The results reveal that soft TQM is the primary driver of quality performance and patient satisfaction in the health care context, which is in stark contrast to the manufacturing sector.

Impact of lean service, workplace environment, and social practices on the operational performance of India post service industry

This paper aims to study the determinants of the Lean Service System (LSS) on the Operational Performance (OP) of India's mail service in the National Sorting Hub (NSH), Mangaluru, Karnataka, the southern part of India. Measuring the OP in mail service is a big challenge in the postal service industry. Hence, we have conducted a survey, and 150 usable data has measured the impact of Lean Service Practices (LSP), Lean Workplace Environment Practices (LWEP), and Lean Social Practices (LSoP) on the OP. The results are analyzed from the partial least square based structural equation modelling (PLS-SEM) with the support of R programming. The analysis shows that there is positive and significant impact of LSP (β = 0.380, p < .05), followed by LWEP (β = 0.281, p < .05), and LSoP (β = 0.266, p < .05) on OP. The practical effect of the findings of LSS are effectively implemented for enhancing the OP of the business. This research addresses the appropriate empirical model to test LSS in India's postal service industry, which is scant in the existing literature. Moreover, this study helps India Post to review its policy so as to sustain the effectiveness of Lean Service (LS) implementation.

The moderating effect of industry clockspeed on Lean Manufacturing implementation in Zimbabwe

Purpose

The purpose of this paper is to analyze the moderating impact of industry clockspeed (IC) on the relationship between Lean Manufacturing (LM) practices and operational performance. A model for evaluating the impact of LM is developed and the moderating effect of IC is taken into consideration as a fundamental variable that affects the causal relationship between LM practices and operational performance.

Design/methodology/approach

A structural equation model was proposed and investigated across two groups based on IC level (Group 1: low IC and Group 2: high IC). A structured survey questionnaire was used to collect empirical data from 600 companies listed by the Confederation of Zimbabwean Industries. A total of 214 usable questionnaires were obtained giving a response rate of 35.6 percent. The data were analyzed using Smart PLS 3 and SPSS version 25.

Findings

The results revealed that LM practices directly and positively affected operational performance and IC had a positive moderation effect on the relationship between LM practices and operational performance. The results indicated that the structural equation model remained invariant across the groups. This showed that IC had a moderating effect on the relationship between LM practices and operational performance for both low IC and high IC industries.

Originality/value

The study analyzed the moderating effect of IC in Zimbabwean industries. The study will provide further evidence to managers on the impact of LM practices on operational performance in developing countries.

An investigation of the relationship between lean and well-being based on the job demands-resources model

Purpose

The purpose of this paper is to investigate how just-in-time (JIT)-related job demands, problem-solving job demands and soft lean practices (SLPs) jointly influence employee well-being in terms of work engagement and exhaustion.

Design/methodology/approach

Based on the job demands-resources model, lean-related job characteristics were classified as resources or demands, and a set of hypotheses was developed to test their effect on work engagement and exhaustion, including the potential interaction between job resources and demands. The hypotheses were tested using moderated hierarchical regression and structural equation modelling, based on data from 138 workers.

Findings

SLPs act as job resources in a lean company, increasing work engagement and reducing exhaustion. Conversely, JIT-related job demands act as a hindrance, reducing work engagement and increasing exhaustion. However, SLPs can reduce the effect of JIT-related job demands on exhaustion, and JIT-related job demands may enhance the positive effects of SLPs on work engagement.

Research limitations/implications

The study provides no conclusive evidence on the hypothesized role of problem-solving as a challenge job demand.

Practical implications

The results can guide practitioners’ understanding of how to implement lean without harm to employee well-being.

Originality/value

By employing a well-grounded psychological model to test the link between lean and well-being, the study finds quantitative support for: the buffering effect of SLPs on exhaustion caused by JIT-related job demands, and for the role of JIT as a hindrance. These novel findings have no precedent in previous survey-based research. In addition, it reveals the importance of studying SLPs at an individual level, as what matters is the extent to which workers perceive SLPs as useful and supportive.

On the application of Lean principles and practices to innovation management

Purpose

Increasingly, a firm’s innovation capability has become one of the key frontiers of competitive advantage. The Lean philosophy has a well-proven reputation for its focus on process efficiency and effectiveness, and therefore, is often applied in various areas of innovation. Such wide and ever-increasing applicability also has resulted in an incoherent corpus of literature on Lean innovation. The purpose of this paper is to conceptualize an integrative view on Lean innovation management.

Design/methodology/approach

Based on a systematic literature review, the key Lean principles and practices useful in the context of innovation management are identified and synthesized into an all-inclusive framework. By means of three illustrative cases (i.e. public hospital, electronics company and avionics manufacturer), this paper elaborates on how the proposed framework can be applied.

Findings

A total of 88 publications are analyzed, leading to 34 Lean principles and practices relevant to innovation management, which are further integrated into a comprehensive model, dubbed the “Leanovation” framework.

Originality/value

This study is the first attempt to advance the understanding of various interrelated and interdependent components of Lean innovation management in a holistic way.

Lean management and operational performance in health care

Purpose

The purpose of this paper is to examine the impact of lean management (LM) on operational performance (OP) in the context of health care in Jordanian private hospitals. LM is measured using four bundles: total quality management (TQM), human resource management (HRM), just-in-time system (JIT) and total productive maintenance (TPM). The study also investigates the effects of OP dimensions on hospitals’ business performance (BP).

Design/methodology/approach

The study is based on survey data collected from 260 respondents from 25 private hospitals in Jordan. Validity and reliability analyses were performed using SPSS and Amos, and the study hypotheses were tested using structural equation modeling.

Findings

The study found that the TQM bundle affects quality performance positively, but does not affect efficiency and accessibility performances, while the HRM bundle positively affects all OP dimensions. Furthermore, the JIT bundle positively contributes to both efficiency and accessibility performances, while the TPM bundle positively influences quality and accessibility performances. Moreover, the results have demonstrated that OP dimensions of quality and accessibility significantly and positively affect hospitals’ BP.

Originality/value

This study is one of the first to adapt the four lean bundles popularized in the manufacturing sector and apply them in a health-care context. It examines the effects of the four lean bundles on hospitals’ OP in terms of efficiency, quality and accessibility. In addition, the study demonstrates the role of OP dimensions in improving private hospitals’ BP.

Socio-technical systems cybersecurity framework

Purpose

This paper aims to identify and appropriately respond to any socio-technical gaps within organisational information and cybersecurity practices. This culminates in the equal emphasis of both the social, technical and environmental factors affecting security practices.

Design/methodology/approach

The socio-technical systems theory was used to develop a conceptual process model for analysing organisational practices in terms of their social, technical and environmental influence. The conceptual process model was then applied to specifically analyse some selected information and cybersecurity frameworks. The outcome of this exercise culminated in the design of a socio-technical systems cybersecurity framework that can be applied to any new or existing information and cybersecurity solutions in the organisation. A framework parameter to help continuously monitor the mutual alignment of the social, technical and environmental dimensions of the socio-technical systems cybersecurity framework was also introduced.

Findings

The results indicate a positive application of the socio-technical systems theory to the information and cybersecurity domain. In particular, the application of the conceptual process model is able to successfully categorise the selected information and cybersecurity practices into either social, technical or environmental practices. However, the validation of the socio-technical systems cybersecurity framework requires time and continuous monitoring in a real-life environment.

Practical implications

This research is beneficial to chief security officers, risk managers, information technology managers, security professionals and academics. They will gain more knowledge and understanding about the need to highlight the equal importance of both the social, technical and environmental dimensions of information and cybersecurity. Further, the less emphasised dimension is posited to open an equal but mutual security vulnerability gap as the more emphasised dimension. Both dimensions must, therefore, equally and jointly be emphasised for optimal security performance in the organisation.

Originality/value

The application of socio-technical systems theory to the information and cybersecurity domain has not received much attention. In this regard, the research adds value to the information and cybersecurity studies where too much emphasis is placed on security software and hardware capabilities.

The relationship between investments in lean practices and operational performance

Purpose

Prior research has shown that operational intellectual capital (OIC) and investments in lean practices (ILP) lead to better operational performance. However, there have been no empirical studies on the synergetic effects between OIC components and ILP. More specifically, the question – can the efficacy of ILP be increased through OIC? – has not been studied. Accordingly, the purpose of this paper is to report the empirical results of potential synergetic effects between OIC, as a knowledge-based resource, and ILP.

Design/methodology/approach

The empirical data used for this study were drawn from the fifth round of the Global Manufacturing Research Group survey project (with data collected from 528 manufacturing plants). The hypotheses are empirically tested using three ordinary least square (OLS) models.

Findings

The authors’ findings highlight the importance of leveraging a system of complementary knowledge-based resources (OIC dimensions) and addresses the need for the reformulation of lean theory in terms of the emergent knowledge-based view of the firm. The results facilitate greater understanding of the complex relationship between ILP and operational performance. Building on the contribution of Menoret al.(2007), the authors argue that OIC represents a strategic knowledge-based resource that is valuable, hard to imitate or substitute and, when leveraged effectively, generates superior operational and competitive advantage.

Practical implications

From a managerial standpoint, this study provides guidelines for managers on how to leverage OIC to enhance the efficacy of ILP. The authors argue that firms consider investing in OIC to increase the return from ILP, which, in turn, will enhance their operational performance and provide competitive advantage. The authors findings provide strong evidence of the importance of human, social and structural capital to enhance the efficacy of ILP.

Originality/value

This is the first research paper that extends the application of the intellectual capital theory in lean literature, and argues that the OIC contributes to the efficacy of ILP. The analysis facilitates greater understanding of the complex relationship between OIC dimensions, ILP and operational performance.

A theoretical framework for the social pillar of lean

Purpose

The purpose of this paper is to propose a theoretical framework for the social pillar of lean (SPL), which is a neglected topic in the lean management literature.

Design/methodology/approach

The authors first identify shortcomings in research on the SPL that are attributable to neglect of relevant perspectives in organisational research. The authors then present a theoretical case outlining the factors that should be considered in SPL research, how they relate to one another and how they should be integrated in future studies of lean change implementation.

Findings

The theoretical framework for the SPL proposes a categorisation of factors and their relationships across levels of analysis that are relevant to the SPL. The inclusion of previously neglected perspectives, such as the relational coordination theory, within this framework offers new insights and directions for research.

Practical implications

By emphasising relationships, the SPL framework sheds light on the scale and complexity of the management challenges involved in lean implementation.

Originality/value

The proposed framework promises to enhance the efficacy of lean research by focussing on factors, such as relationships, that are most relevant to lean implementation.

Lean management and innovation performance

Purpose

The purpose of this paper is to explore the effects of innovation orientation (IO) on both the implementation levels of soft and hard lean management (LM), as well as innovation performance. It also aims at exploring the effects of soft and hard LM on innovation performance.

Design/methodology/approach

The study analyzes survey data collected as a part of a high-performance manufacturing (HPM) project from 238 international manufacturing companies in eight countries and three industries. Exploratory factor analysis and confirmatory factor analysis were applied to assess construct validity. The study hypotheses were tested using structural equation modeling.

Findings

The results demonstrated that innovation-oriented companies tend to adopt aspects of both soft and hard LM. However, the results revealed an insignificant effect of soft and hard LM on innovation performance. The study also showed that innovation performance is positively influenced by an IO. These results indicate that having an IO is vital for enhancing both LM as well as innovation performance. They also evidently suggest that LM is more related to continuous improvement (incremental innovation) rather than (radical) innovation and, as such, is not important for firm’s intent on enhancing their innovation performance.

Practical implications

The current study demonstrates that IO and LM are complementary and not contradicting strategies. The two strategies share many cultural aspects, similarities and commonalities. However, LM is not sufficient to predict innovation performance. Managers of the surveyed manufacturing firms are advised to focus on IO, as it has beneficial impacts on both LM (continuous improvement initiatives) as well as innovation performance. This clearly indicates that placing the emphasis upon radical (innovative) improvement rather than incremental improvement (LM practices) is believed to support continuous and innovative improvement alike.

Originality/value

The relationship between LM and innovation is debated in the existing literature, but the debate is characterized by a lack of empirical evidence. This is one of the first studies that empirically investigates the relationships between IO, LM and innovation performance. It identifies some new insights to direct future research, particularly regarding different innovation types as well as in service organizations.

Toyota Kata as a KM solution to the inhibitors of implementing lean service in service companies

Purpose

This paper aims to resolve the inhibitors of lean service using knowledge management (KM) concepts through the use of Toyota Kata. To achieve this, the authors updated the research on lean supportive practices and inhibitors of lean technical practices presented by Hadid and Afshin Mansouri (2014) through a systematic literature review (SLR). The SLR focused on empirical studies/cases from the past 15 years and confirmed the inhibitors of lean technical practices. As a result, Toyota Kata is proposed as a KM solution to the inhibitors of lean service implementation in service companies.

Design/methodology/approach

The authors carried out an SLR to identify inhibitors of lean service in real case applications and analyzed the resulting bibliographic portfolio using KM as a lens, along with three theories: universal theory, socio-technical systems theory and contingency theory, which assist in highlighting and clarifying the potential impact of using Toyota Kata as a solution to the inhibitors of lean technical practices.

Findings

When the authors analyzed the inhibitors of lean technical practices, they discovered that there is a strong relationship between the inhibitors and the individual (staff) personal characteristics regarding commitment, involvement, communication and preparation. These inhibitors and characteristics should work as a system, and Toyota Kata improves people’s skills and process performance by connecting people, processes and technology. Also, the authors noted that the Toyota Kata concept used can provide benefits in the implementation of lean service for companies, such as the internalization of continuous improvement, this becoming part of the company culture. Moreover, it has been demonstrated that Toyota Kata provides an effective way to achieve KM.

Research limitations/implications

This study may not have enabled a complete coverage of all existing peer-reviewed articles in the field of practices and inhibitors presented by Hadid and Afshin Mansouri (2014). However, it seems reasonable to assume that in this review, a large proportion of the studies available was included.

Practical implications

This paper opens a new perspective on the use of Toyota Kata by managers as a solution to implement KM, spinning the spiral of knowledge.

Originality/value

This is the first study that seeks empirical evidence of inhibitors of lean technical practices and proposes Toyota Kata as a KM Solution for these issues. As a result, this study advances the facility to overcome these inhibitors, opening a new perspective for management to lead in achieving operational excellence.

Can continuous improvement lead to satisfied customers? Evidence from the services industry

Purpose

To achieve higher customer satisfaction (CS), companies implement continuous improvement (CI) programs, regardless of the growing evidence of their failure to achieve declared goals. The purpose of this paper is twofold: first, to identify whether companies are able to improve CS through the application of CI; and, second, to identify what organizational practices are able to facilitate the impact of CI on CS.

Design/methodology/approach

To test the developed assumptions, the study uses the structural equation modeling technique. The data for analysis were collected from 304 service companies via a custom web-survey.

Findings

The research confirms the direct positive impact of CI on CS. Further, the study demonstrates that management commitment and rewards system that encourages employees to participate in CI play the major facilitating role in improving CS through CI. These practices accompanied by quality-oriented culture and employee training in the improvement tools provide necessary infrastructure to sustain CI in the companies over time. Additionally, regardless of the vital role of goal setting for CI established in previous research, the proposed study finds a limited ability of goal setting, as compared to other organizational practices, to facilitate CI–CS relationship.

Originality/value

The study contributes to the scarce field of research on CI implementation in the services environment. Further, the research assesses CS as a variable of interest, as opposite to the previous studies, considering CS as a part of the composite variable. The research assesses the impact of the training in CI methodology on the CI–CS relationship, while previous research focuses on the general, work-related training. The findings provide an important basis for further academic work in the area of quality management. The identified practices can serve as guidance for managers, implementing CI in their companies due to the high fit of the proposed model.

Buyers’ switching intentions in a manufacturing supply chain: a migration theory perspective

Purpose

The purpose of this paper is to identify the negative impact of an incumbent supplier pushing out a buyer, the positive effect of an alternative supplier pulling a buyer, and the mooring impact that prevents a buyer from switching to a supplier in terms of the push-pull-mooring (PPM) model of migration theory. In this context, this study considers a buyer as the immigrant, an incumbent supplier as the origin, an alternative supplier as the destination, and inertia as the hesitance to migrate.

Design/methodology/approach

This study collected survey data from 148 end-product manufacturers and first-tier suppliers. It tested whether the PPM model fit in a supply chain relationship (SCR) using the partial least squares structural equation modelling approach and SmartPLS package version 2.0.M3.

Findings

The results support all hypotheses for causal relationships among factors of cognitive, affect, and behavioural intentions of each PPM effect. This study identifies the relative importance of each effect on a buyer’s intention of switching an existing supplier.

Originality/value

This study presents a new perspective that enhances the understanding of a buyer’s behaviour towards a supplier by applying the PPM model of migration to a manufacturing SCR. It promotes interdisciplinary and integrated views as well as broadens the diversity of the results in the business-to-business context.

A quality system’s impact on the service experience

Purpose

The purpose of this paper is to examine the interplay between technical and social systems within an organization that potentially affect the service experience, as perceived by end customers.

Design/methodology/approach

The paper explores the potential impact of an integrated service quality system on the service experience. A conceptual model is presented, accompanied by a detailed development of the hypotheses. Two samples (Study 1: n=474, Study 2: n=225) of consumers are used to empirically test the proposed model.

Findings

The analysis reveals the impact a technical system has on employees’ inherent abilities (i.e. the social system), which, in turn, affect the overall assessment by customers. Additionally, the situation in which an employee works (i.e. operating environmental conditions) results in differences in the model.

Research limitations/implications

This paper’s main implication is this paper employs established theory to develop a model that is empirically tested to show that implementing and maintaining a quality-oriented service system can positively influence the overall customer experience. The limitations are based primarily on the methodology in which individual employees assessed all aspects of both the social and technical systems.

Practical implications

Managers should be diligent in their design and implementation of the quality components as these affect the work setting in which employees operate.

Originality/value

Prior research has neither explored an integrated service quality system’s impact on the service experience nor employed an established theoretical framework. This work accomplishes both with the results providing contributions to both theory and practice.
