As the demand for efficiency and quality in the health-care industry has increased over the past few years, adoption of Lean principles and tools in the medical laboratory industry has become increasingly crucial. The purpose of this study is to explore the level of adoption, barriers and enablers of Lean principles and tools in the Namibian medical laboratory industry.

A descriptive cross-sectional study was carried out to examine the level of usage, barriers and enablers, impact of Lean tools and to suggest appropriate strategies for adopting Lean in the Namibian medical laboratory services.

Research findings reveal that Lean tools are moderately implemented in most laboratories. Standard operating procedures, root cause analysis, overall equipment effectiveness and visual management are the important Lean tools used in the industry. Results of the survey also show that Lean tools had a positive impact on operational performance, employee motivation, turnaround time and cost reduction. Furthermore, top management involvement, adequate training and proper planning emerged as important enablers, while lack of support from the management, financial constraint and staff resistant to change are major barriers to the adoption of Lean principles in the Namibian medical laboratory industry.

The paper has inherent limitations of survey research, which the authors will overcome by using case studies with medical laboratories.

The findings of the authors’ work will help in widening the application of Lean principles in more medical laboratories in Namibia and in other parts of the world.

The paper is based on numerous health-care studies on Lean. This is one of the few papers investigating the adoption of Lean principles, specifically in medical laboratories, from an emerging economy such as Namibia.

Lean construction looks into the possibility of bringing successful lean production theories into the construction industry. It was believed that lean production principles could also be influenced by the essence of military strategies, specifically that of Sun Tzu's Art of War (ST) when these were introduced many years ago. This study looks into the practices of lean construction in the industry and the similarities in the two sets of statements from lean construction principles and Sun Tzu's strategic principles.

Surveys and interviews of 40 project managers in the construction industry were conducted.

The study suggests that there are some agreements between lean construction principles and Sun Tzu's strategic principles.

This study raises the interesting question of whether the origin of lean construction principles can be traced to the strategic principles formulated by Sun Tzu some 2,500 years ago.

It is recommended that the strategic principles formulated by Sun Tzu be tapped upon for the further extension of lean principles (LP) in construction.

The value of this paper lies in its reflections of ST to better understand the possible origin of current lean construction principles and practices.

The purpose of this study is to systematically analyse and synthesise the existing research published on offsite manufacturing/construction. The study aims to highlight and associate the core elements for adopting the offsite concept in different construction contexts. This ultimately facilitates the enhancement of the offsite uptake.

The research study was carried out through a systematic literature review (SLR). The SLR was conducted to identify and understand the existing themes in the offsite research landscape, evaluate contributions and compile knowledge, thereby identifying potential directions of future research. The grand electronic databases were explored to gather literature on the offsite concept, lean and agile principles and simulation. A total of 62 related articles published between 1992 and 2015 have been included in this study. The relevant literature was systematically analysed and synthesised to present the emerging offsite themes.

The descriptive and thematic analyses presented in this paper have identified related offsite research studies that have contributed to setting a firm foundation of the offsite concept in different construction contexts. Each of the 62 articles was examined for achieving the aim and objectives of this study, the method of data collection and coverage of offsite themes. The results of the analyses revealed that the articles mostly provide information on the offsite concept and its definitions (53 per cent) and offsite barriers and/or drivers (27 per cent). However, limited attention has been paid to the integration of lean and agile principles (13 per cent) and simulation (7 per cent) within the offsite concept, which are therefore more open to research within the offsite concept.

The literature review highlights the main themes and components of the offsite construction concept. This forms a solid basis and motivation for researchers and practitioners to build on to enhance the uptake of the offsite concept in different contexts. This study also presents a research roadmap within the offsite concept, along with a recommendation for further research to be conducted using the research framework proposed in this study. The framework could lead to validation of using simulation to integrate lean and agile principles within the offsite concept.

This paper presents a systematic review of the literature related to offsite construction in different contexts. The emerging components, that is, offsite definitions, drivers and/or barriers, lean and agile principles and simulation have been highlighted and discussed thematically. A research framework that enables pursuit of the integration of lean and agile principles offsite through the lens of simulation has been proposed. The framework is expected to open up new opportunities on the effectiveness of offsite development in different contexts.

The purpose of this research is to study the impact of perceived adoption of Lean principles on operational performance in Lebanese pharmaceutical industries.

A quantitative method was implemented using a questionnaire that targeted 253 respondents working in eight good manufacturing practices (GMP) certified Lebanese pharmaceutical companies. Reliability analysis was performed using SPSS, and the research hypotheses were tested using regression analysis.

The results demonstrated that Lean principles positively and directly affected operational performance. It also positively affected operational performance factors of quality, cost and time. However, the analysis of each of Lean principles impact on operational performance cost was analyzed perfection, value, and value stream mapping (VSM) significantly increased operational performance. In addition, pull only positively augmented the cost reduction, whereas flow did not show any effects on any of operational performance’s factors.

In addition to enhancing operational performance, the positive effect of the perceived adoption of Lean principles on performance is also explained by managers’ efforts in studying the flow of actions in their processes to reduce wastes. To face uncertainty, training and building a workforce that is able to implement Lean principles, equipping this workforce with needed artifacts, and promoting a high-performance culture are crucial for the successful implementation of Lean principles.

Lean approach has become a major pathway of improvement especially in pharmaceutical companies. Few studies analyzed the impact of each of the Lean principles on the operational performance in companies that operate in era of uncertainty. Furthermore, the perceived adoption of Lean principles is under investigated in the Middle East in general and in Lebanon in particular.

The purpose of this study is to enhance the understanding of Japanese Lean management principles in South African contexts using Ubuntu, to improve buy-in during Lean implementation.

A scoping systematic literature review (SLR) was used to investigate the correlations and variations between Lean management principles and Ubuntu management principles.

Both similarities and differences were discovered between Ubuntu and Lean. It was noted that Lean adopts principles that do not have corresponding Ubuntu principles, such as levelling out workload, continuous process flow, stopping to fix the problem and visual management.

While this research only used a South African concept (Ubuntu) to develop a novel Lean analogy, future research could be pursued in a similar vein for other countries outside of Japan.

The similarities could assist in “translating” Lean concepts to a South African context, ergo improving the understanding of the Lean principles and possibly contributing to more successful Lean implementations.

To the researcher’s knowledge at time of publication, this study is the first comparison of these two management philosophies. Ergo, the Lean–Ubuntu analogy is a novel comparison of Lean.

A comprehensive literature review was conducted to identify the lean principles and the challenges of building refurbishment. To have an in-depth investigation of the application of lean principles to address the challenges of refurbishment projects, ten expert interviews following a qualitative research approach were utilised in this research. Data were analysed using manual content analysis to derive the framework.

The refurbishment of buildings has attracted the attention of the present construction industry. However, uncertain project characteristics, information deficiency, limited space for construction activities and less stakeholder involvement make it complex. Since the lean concept effectively deals with complex and uncertain projects, this study focusses to investigate the application of lean principles to overcome the challenges of refurbishment projects in Sri Lanka by developing a framework.

It was found that the five main lean principles of customer value, value stream, value flow, pull and perfection are appropriate for building refurbishment projects in Sri Lanka. Precise identification of clients and end-users, value adding and non-value adding activities, interruptions and stakeholder communication chains, setting scope, examining the possible technologies and taking measures to deliver the exact product to ensure the successful application of lean principles for refurbishment projects. Further, 27 benefits of five lean principles were identified which can be used to address the 13 identified challenges of building refurbishment of projects. Finally, a framework has developed portraying the application of lean principles in building refurbishment.

The framework developed is beneficial for the building refurbishment project team to address the barriers of refurbishment projects by applying lean principles.

This framework can be used as a guideline for the implementation of building refurbishment projects by addressing their challenges with lean principles.

In times of strong global competition and worldwide economic downturn, there is an imperative need for public services organizations to reform and improve their quality. These organizations can base their improvement efforts on Lean philosophy. The purpose of this study is to assess the employees’ perceived degree of adoption of Lean principles by public services organizations in Greece. Determining the differences in the perceptions of groups of employees with regard to the adoption of Lean principles by public organizations is also an aim of the study.

A questionnaire survey was published online, inviting employees of Greek public services organizations to assess the degree of Lean adoption by their organizations, specified on the basis of general principles. A total of 1,022 employees completed the structured questionnaire. Descriptive statistics were applied to assess the degree of adoption of Lean principles by public organizations. The nonparametric Mann–Whitney U Test and Kruskal–Wallis Test were also applied to determine whether there are statistically significant differences in the perceptions of groups of employees with regard to the adoption of Lean principles by public organizations.

According to the perceptions of employees, Greek public organizations adopt Lean principles to a high extent. However, there is room for further improvement in the degree to which Lean is adopted. Statistically significant differences are observed in the perceptions of groups of employees from different sized organizations, hierarchical levels, skill sets and service subsectors, with regard to the degree of adoption of Lean principles by their organizations.

The employees of the public sector who were invited to respond to the survey through social media, the subjective nature of the data collected and the fact that this is a country-specific study constitute the main limitations of the present study, based on which future studies can be designed.

By determining the strong and weak points of the adoption of Lean principles by Greek public services organizations, suitable managerial initiatives can be undertaken by these organizations to fully adopt Lean, eliminate waste and enhance quality management.

Understanding and improving the current status of the adoption of Lean principles by Greek public organizations will influence the services provided to the citizens in terms of time, quality and delivery.

To the best of the authors’ knowledge, this is the first study which provides insights, based on employees’ perceptions, into the adoption of Lean by the public services sector.

Service productivity continues to receive ever‐greater amounts of attention as service covers a greater portion of the economy. As competition increases, service productivity becomes increasingly important. This study aims to explore the applicability of lean principles in a service context and to conceptualize how these principles impact service productivity.

This paper presents a conceptual analysis of the six most commonly used lean principles in manufacturing and their applicability to a service context for different types of services. Using this analysis, six propositions are developed to examine the influence of lean on service productivity.

This study suggests promising synergies, as well as important obstacles, for applying lean principles in services. Standardizing services and increasing reliability in service processes through lean principles can increase efficiency. However, the customer's active role in certain services and, simultaneously, high diversity make the application of lean principles increasingly difficult. Also, customer satisfaction must be considered when improving service productivity, otherwise the positive long‐term effects of a lean approach in service will be absent.

These findings are useful for organizations aiming to improve their service productivity. Particularly, lean principles are invaluable to increase efficiency and customer satisfaction for services with low diversity and low customer participation. This paper suggests a direction for the proper use of lean principles for different service types, and how efficiency and customer satisfaction are affected through a lean approach.

This study contributes to the research on service productivity and continues the discussion on prototypic characteristics of service and manufacturing orientations.

Lean construction (LC) is an innovative approach in the construction industry that has shown significant success in developed countries. Although LC has potential in the construction sector of Pakistan, it has not been extensively explored. This study aims to address this knowledge gap by identifying and predicting current lean practices and assessing the strengths and weaknesses of LC implementation in Pakistan.

Using robust statistical methods to analyze 92 valid responses, the study reveals that approximately 54% of lean practices are currently in use in the construction industry of Pakistan, with a population mean ranging from 52.7% to 55.6%.

Surprisingly, the research identifies instances where some construction firms in Pakistan are implementing LC practices, even though they have only a limited understanding of its underlying principles. Notably, certain subprinciples, such as visual management, top management commitment to change, employee training, process cycle time reduction and production optimization, are less integrated within the construction industry. Exploring the possibility of implementing LC, recommendations for strategies to implement LC in Pakistan are suggested, aligning with the conceptual model proposed by the researchers.

The novelty of this work offers insights that can serve as a comprehensive guide for developing nations. It provides a structured approach to assess and benchmark LC practices, which, in turn, can contribute to a more efficient and effective construction industry. Moreover, the strategies proposed in this research can aid developing countries in the efficient implementation of LC. This will have a positive implication for both economic and developmental outcomes.

The lean enterprise model has been adopted in a wide range of industries beyond its origins in the motor industry. To achieve this there has been a considerable extension of the lean concept outside high-volume repetitive manufacture. The purpose of this paper is to present an in-depth study of the application of lean within the British Royal Air Force. It offers a number of new insights which have implications for the future development and adoption of lean in service contexts, and the public sector in particular.

To illustrate the issues of application of lean outside automotive, this paper considers the adoption of the lean concept by the Tornado joint integrated project team within the UK Ministry of Defence. A review of methods of application of lean used within Tornado are studied. The paper considers how the fundamental principles of lean apply in this environment and how, considering these principles, methods of implementation should be modified.

This paper finds that the five lean fundamental principles apply in Tornado but they need to considered specifically within the public service context particularly the pull principle. Hence the authors offer three propositions relating to the use of the lean principles of value, waste, flow and pull in the public sector, and one for perfection only relating to military organisations.

This paper makes an important contribution by demonstrating that lean can be successfully applied, in a public service context, with only modest modifications to its core principles, principally about how customer demand (pull) is managed. The implication of this finding demonstrates that to be adopted successfully, lean must be adapted to its context and the lean principles need to be reviewed too.
