Purpose Lean management is a contemporary management system that firms adopt to boost their performance. Lean management can be integrated with human resources management to develop a new concept of lean human resources management (LHRM). This entails the implementation of several practices. However, the LHRM–performance paradigm remains underexplored in the literature. Hence, this study aims to examine the interrelationships between LHRM practices and the impacts of those practices on firm performance (FP). Design/methodology/approach Using two equal-sized samples (n = 250 each) of manufacturing firms in Jordan and Germany, this study proposes two structural equation models (i.e. a Jordanian and a German models) depicting the interrelationships between LHRM practices and the impacts of those practices on FP. After testing these models, a comparison between them is conducted, producing findings with theoretical and practical implications. Findings The main findings of this study indicate that the average implementation of LHRM practices among German manufacturing firms is at a higher level than the average implementation among Jordanian firms. The findings also support the proposed interrelationships between LHRM practices and the impact of those practices on FP for both the Jordanian and German models. Originality/value To the best of the authors’ knowledge, this study is among the first to highlight the proposed relationships, both in general and in the context of comparing developed and developing countries. Its findings have important implications that can enable manufacturing managers to benefit from the implementation of LHRM practices to enhance FP in different contexts. These findings provide valuable insights for human resource managers and decision-makers and open several avenues for future research.

Purpose The purpose of this paper was to develop a quantitative classroom observation method that is able to analyse the school day to identify Time-on-Task losses comprehensively and systematically, at a level of detail that can be used by teachers and principals to stimulate and focus practical improvement efforts. Design/methodology/approach The novel Time-on-Task Analysis (TOTA) model was developed by triangulating the conceptual framework of the Overall Equipment Effectiveness metric with the semantics and structure of the target domain. Once developed, the model was tested structurally against a time-series classroom observation data set, after which the resulting TOTA was presented to a sample of 52 education stakeholders, who then gave their perspectives of the analysis in a structured survey. Findings The ontological model was found to be accurate, complete and without conceptual incongruencies, and its output novel and useful by the sample of education stakeholders. Of the participants, 90.3% found the analysis to provide a new perspective, 94.2% reported that the analysis triggered improvement ideas and 80.8% thought that their school(s) could benefit from a TOTA study. Originality/value The TOTA model introduces a time-loss-focused perspective to the field of quantitative classroom observation studies, which is dominated by more sociologic- and pedagogic-focused topics. Its grounding in Overall Equipment Effectiveness also gives it a more detailed and systematic approach than the few Time-on-Task studies done to date, resulting in a model made for the “Gemba”: the school classroom.

Purpose The purpose of this paper is to propose a novel lean management tool to provide a comprehensive and flexible evaluation model while converting customer voices into technical characteristics in lean implementations. Design/methodology/approach For this purpose, the proposed model was constructed by belief space-evaluations, quality function deployment (QFD) and analytic hierarchy process (AHP) in interval type-2 fuzzy (IT2F) environment. This model involves three phases: determining the linguistic weights and belief-based relations with their IT2F-sets, processing information about IT2F-based belief-evaluations and ranking the technical characteristics using the defuzzified belief-based relative importance values. Findings The proposed model was applied to automotive after-sales service in Turkey to demonstrate its use in lean service-decisions. This model was compared with its classical and type-1 fuzzy versions. The ranking-results of the proposed model differed from those of the other versions. The reason is that the IT2F-environment offers a sensitive and flexible evaluation of the model’s linguistic scales. Research limitations/implications Calculations in the proposed model may be quite involved for practitioners. An Excel-dashboard was created to simplify the computational complexity. Practical implications Researchers/practitioners can apply this model to any lean manufacturing/service implementation. Social implications Company managers/employees/customers can recognize their perception-mechanisms via belief space-evaluations and experience how uncertainty in the perception-mechanism affects their decisions. Originality/value The proposed model provides a new lean tool due to the Bayesian model combined with QFD-AHP in IT2F-environment. This model eliminates the ambiguity in conceptual change-based lean decisions.

Purpose Evidence indicates that the Indian economy has grown enormously in recent years. and Lean Six Sigma (LSS) has evolved globally as a structured business improvement strategy with diverse applicability in the last fifteen years. Therefore, this paper aims to investigate the status of LSS implementation in Indian industries using a survey research technique. Design/methodology/approach A survey questionnaire was devised from the literature, containing 25 questions to assess respondents’ awareness of the LSS methodology and gain insights on aspects associated with LSS adoption in Indian industries. The survey questionnaire was validated and was conducted using randomly sampled respondents from the Confederation of Indian Industries membership database. The collected data were statistically analyzed using IBM SPSS and MS Excel. Findings The findings attest that adopting LSS is not so encouraging and extremely poor in small- and medium-scale Indian industries. ISO 9001 emerged as a prominent quality improvement program. It is learnt that consultants play a pivotal role in bringing awareness and skills building while implementing LSS. Results endorse top management commitment and involvement, and resistance to change as leading success factors and challenges, respectively. Further, it is revealed that respondents were highly satisfied after the adoption of LSS. Research limitations/implications The findings of this study were derived from 183 responses and should be generalized cautiously. Originality/value This paper provides valuable insights on the present status covering the issues related to L:SS implementation in India. These results can motivate the managers of Indian industries for wide adoption of the LSS methodology. In addition, the findings of the paper may assist the researchers providing direction to carry out further research in LSS in the Indian context.

Purpose With the emergence of the COVID-19 pandemic, the production shortage of personal protective equipment (PPE), such as surgical masks, has become increasingly significant. It is vital to quickly provide high-quality, hygienic PPE during pandemic periods. This comprehensive case study aims to confirm that Kaizen and 5S applications reduce wastage rates and stoppages, which as a result, created a more efficient and sustainable workplace in a small–mediumenterprise (SME) producing PPE in Turkey. Design/methodology/approach The method for this case is discussed with the help of a flowchart using the DMAIC cycle: D-define, M-measure, A-analyse, I-improve and C-control. Findings The total stoppages due to fishing line, gripper, piston and yarn welding have decreased by approximately 42.4%. As a result of eliminating wasted time and reduced changeovers, a total of 5,502 min have been saved per month. This increased production of approximately 10.55% per month, led to an addition of 506,184 units. Originality/value The use of lean manufacturing (LM), Six Sigma, Lean Six Sigma and continuous improvement methodologies are not common in textile SMEs. Based on the current literature reviewed, to the best of the authors’ knowledge, this is the first comprehensive case study that combines statistical tools, such as hypothesis tests and LM practices, in the production process for a PPE company operating as a textile SME.

Purpose The Design For Six Sigma (DFSS) methodology is one of the most important to achieving excellence in an organization’s product development process. This paper aims to propose a roadmap for product development based on the DFSS for the consumer durables manufacturing industries. The proposed roadmap presents a systematic approach to the phases of the product development process, integrating the statistical techniques and quality tools that should be used in each phase. Design/methodology/approach This study presents a detailed roadmap for product development, which was built by identifying gaps in the DFSS methods, based on previous studies on the subject. In this step, the opportunities are provided in all phases from creation to discontinuation of the product in the market. In addition, the roadmap presented was validated by team of stakeholders in the product development process of different industrial companies. Findings The proposed roadmap for the product development process based on six sigma design suggests a visual tool with sequential steps and techniques that allow you to follow the evolution of the development process from idea conception until the product is discontinued in the market. Identifying the priorities of organizations, especially the consumer, regarding the quality and reliability of the product. Practical implications The roadmap seeks to facilitate an understanding of the important stages of the product development process and to provide an approach to improving and optimizing the product before the manufacturing process step through the principles of DFSS methodology. This research provides a guide step by step to apply statistical techniques and quality tools in the product development process to achieve high quality and six sigma level in the manufacturing process. Originality/value The proposed roadmap of this research combines design for sigma and product development concepts, covering a wide spectrum of relevant activities that include the product development process, the application of statistical techniques and the design of high-quality durable consumer goods to match manufacturing technologies.

Purpose Despite the benefits provided by the implementation of the lean philosophy, the most recent research discusses whether the high degrees of efficiency obtained with the implementation this philosophy could contribute positively or negatively in current pandemic scenario. This study aims to analyze how resilient construction industry companies in Brazil were in the face of the COVID-19 pandemic, comparing the performance of construction companies with different implementation levels of lean construction. Design/methodology/approach Three case studies were carried out in construction companies in Brazil with different application levels of the lean philosophy. Findings Among the results obtained, greater resilience to face COVID-19 was verified in those with a higher implementation level of the lean philosophy. Additionally, it was found that the larger the size of the companies surveyed, the greater the level of implementation of the lean philosophy. Research limitations/implications Due to the state of pandemic, and the work carried out in the home office, contact with companies was restricted. In addition, few companies actually adopt the lean philosophy in the construction sector in Brazil. Most of companies use only a few lean construction tools in specific sectors. For the few others who actually implement the philosophy, the acceptance to participate in the research was low. Originality/value The lean construction is something very new and innovative for the construction sector in Brazil, and there is little evidence of its use. Few companies adopt the philosophy in the country, and many of them also did not experience such an impactful moment in their entire existence. Thus, the analysis of the relationship between lean construction and resilience in the civil construction sector in Brazil is something innovative.

Purpose The purpose of this paper is to evaluate how temporary labor moderates the relation between two well-known lean initiatives (process flow and process quality) and line productivity. This paper focuses on high-volume, low-variety (HVLV) shop floors, where work experience may not be as relevant as expected and extrinsic motivation of the temporary workforce could become a key driver of individual performance. Design/methodology/approach The authors follow an insider econometrics approach based on panel microdata (1,793 observations) from nine lines over two years in a Spanish manufacturing plant. The authors selected this setting for two reasons: Spain has traditionally had one of the highest levels of temporary employment in the world, so it perfectly represents labor market trends in OECD countries. Simultaneously, the authors also searched for a type of shop floor that could be representative of one of the most common manufacturing environments: a shop floor with highly repetitive and low-complexity work tasks. Findings The results of this paper suggest that in HVLV environments, temporary labor could contribute up to a 1.4% improvement in line productivity, provided there is a strong lean implementation. Otherwise, the use of temporary labor could undermine the positive effects of both process flow and process quality on plant productivity. Originality/value External incentives derived from high levels of unemployment, coupled with manufacturing’s increasing automation and specialization, may be minimizing the weaknesses traditionally associated with temporary workers in lean environments. By contrast, those shop floors lacking lean standards face serious productivity consequences from adjusting to global trends by using temporary work.

Purpose The purpose of this study is to enhance the understanding of the complete process of framing and implementing operational excellence in the pharmaceutical industry to ensure higher regulatory compliance. Design/methodology/approach A literature search was conducted using preferred reporting items for systematic reviews and meta-analyses guidelines. Strategies were set with different keywords and certain assessment criteria for the inclusion and exclusion of articles. A total of 46 articles were considered for a full review. Findings This study describes the impact of implementing operational excellence in day-to-day operations and the driving forces to achieve the same. Seven commonly used enablers are described can be used in combination to develop and validate an assessment model. Case studies are summarized to schematize operational excellence programs for the scope of their industry. Research limitations/implications This study is limited to Indian pharmaceutical manufacturers. It is implied toward small-scale manufacturers. It can be further extended to manufacturers from other regions. Practical implications This study guides quality assurance managers, regulatory agencies and other top management to implement operational excellence to ensure higher regulatory compliance. It guides to develop a roadmap to operational excellence in their scope. This study is applicable to any manufacturing industry bound to comply with pharmaceutical regulatory standards. Originality/value To the best of the authors’ knowledge, at the time of publication, there are regulatory guidelines and some articles on various key enablers to achieve operational excellence. There is no published systematic review on achieving regulatory compliance by using operational excellence.

Purpose The purpose of this study is to share how the learning impact of a remote workshop was improved through action research practices, especially action inquiry and critical reflexivity. Design/methodology/approach Research design detailed herein consists of one complete cycle of action and reflection. Methods used include: journaling into four territories of experience, free-form journaling, individual and joint reflection using four parts of speech and extended ways of knowing. Findings Action inquiry and critical reflexivity have shown themselves to be a potent means of improving the learning outcomes of remote Playing Lean workshops. Drawing on early insight, the author suggests several venues for further inquiry. Originality/value This paper contributes a novel combination of action research practices that can be used for improving other learning initiatives as well, and an example of how to question the veracity of qualitative findings.
