The aim of this study is to investigate the outcomes of a leading Swedish truck maker (referred to as “TruckCo” for confidentiality reasons) providing lean training to its strategic suppliers.

A single in-depth case study is conducted, using on-site semi-structured interviews with representatives from TruckCo and its suppliers for data collection.

The lean training program resulted in four main outcomes. First, financially unstable suppliers were less receptive to the lean training program than financially stable suppliers. Second, the suppliers became easier to collaborate with over time, through improving their internal ways of working and thus creating more trust in terms of reliability. Third, the suppliers improved their ability to identify possible problems that could jeopardize deliveries. Fourth and finally, the suppliers improved their delivery precision.

One limitation of this study is that its findings are based on a single in-depth case study. Another limitation is that all the involved companies originate from Sweden. These limitations should be considered in attempts to replicate or further test the reported findings.

This study provides insights into how a manufacturer can teach lean management to suppliers, and how suppliers can be involved in a manufacturer's journey towards a leaner supply chain. Furthermore, the study reflects more generally on the potential outcomes of a manufacturer providing lean training to suppliers.

This study highlights both TruckCo's and the suppliers' view of the outcomes of the lean training program and discusses how different suppliers adopt the taught lean practices. Avenues for future research are proposed as well.

Modern supply chains are at risk as a result of increasing disturbance. The use of Lean and Six Sigma’'s values, methods and tools can be one option to analyze, prevent and mitigate risks. The purpose of this study is to investigate whether a combined Lean Six Sigma philosophy can support the awareness and management of supply-chain risk.

The methodology followed in the study is based on a literature review and multiple case study, performed by means of qualitative methods of data collection, such as observations on-site, face-to-face interviews and document analysis. Case selection includes the results of research conducted in seven large Swedish companies.

It has been indicated that Lean and Six Sigma values, methods and tools can be very effective in companies’ efforts to control the supply-chain risks and that they improve the companies’ ability to handle variability and risk management. Lean Six Sigma supports a risk-management culture in the focal companies, but they must involve customers and companies in the supply chain if they wish to create a risk-management culture in the entire supply chain. In order to do this, they can use the Six Sigma training structure, but they need to include more risk tools and methods developed for the supply chain management. It has also been indicated in the literature that if more people involve in 6S projects, the financial results will be better, and the innovation of processes will increase.

These include suggestions for how the companies can use the Six sigma training structure to collaborate in the supply chain.

This study gives practical suggestions for how the companies in supply chain can collaborate and use the Six Sigma training structure for creating a more holistic view of supply chain, which also decrease risks in supply chain.

This study indicates that Lean Six Sigma supports risk awareness and management in the focal companies of the supply chains, which improves companies’ ability to handle variability and risk management. It has also been demonstrated that the companies should use the Six Sigma framework, especially training, as a foundation, and they should create common projects for better collaboration in the supply chain, which will decrease the risks in the entire supply chain.

This paper aims to characterize a sample of Lean Six Sigma (LSS) projects in healthcare settings and discuss some specificities of operational excellence (OPEX) initiatives in hospitals and healthcare organizations in the USA.

A content analysis involving a sample of 23 documents shared by US hospitals was performed in order to achieve the research objectives. Such analysis was based on a conceptual framework developed from the literature review. It was also applied to a quantitative approach, including descriptive statistics, hypothesis testing and correspondence analysis that supported the research.

Most LSSH projects were focused on business transformation and strategic improvements. Simple techniques and tools were predominant such as descriptive statistics, process mapping, 5S and spaghetti charts, usually implemented by Green Belts and Black Belts through the define, measure, analyze, improve and control (DMAIC) method. In addition to the expressive findings reported, these projects' results have been aligned with lead time and operational cost reduction, quality improvement and capacity increase.

The study adds knowledge to the OPEX literature by analyzing the Lean Six Sigma healthcare (LSSH) in hospitals and healthcare institutions in the USA. It also demonstrates that different approaches, such as the kaizen event and DMAIC project show different results according to some techniques and tools applied in the hospital environment.

The empirical evidence presented in this study provides scenery of the LSS practices in the healthcare settings, highlighting the implementation areas, outcomes, tools and techniques mostly used in the North American healthcare institutions.

During the last decades, different quality management concepts, including total quality management (TQM), six sigma and lean, have been applied by many different organisations. Although much important work has been documented regarding TQM, six sigma and lean, a number of questions remain concerning the applicability of these concepts in various organisations and contexts. Hence, the purpose of this paper is to describe the similarities and differences between the concepts, including an evaluation and criticism of each concept.

Within a case study, a literature review and face‐to‐face interviews in typical TQM, six sigma and lean organisations have been carried out.

While TQM, six sigma and lean have many similarities, especially concerning origin, methodologies, tools and effects, they differ in some areas, in particular concerning the main theory, approach and the main criticism. The lean concept is slightly different from TQM and six sigma. However, there is a lot to gain if organisations are able to combine these three concepts, as they are complementary. Six sigma and lean are excellent road‐maps, which could be used one by one or combined, together with the values in TQM.

The paper provides guidance to organisations regarding the applicability and properties of quality concepts. Organisations need to work continuously with customer‐orientated activities in order to survive; irrespective of how these activities are labelled. The paper will also serve as a basis for further research in this area, focusing on practical experience of these concepts.

The purpose of this paper is to elaborate, how the use of a joint-use strategy of Lean and Six Sigma can improve flexibility, robustness, and agility. Telecom manufacturing has been under tremendous change after dot.com bubble burst in the early 2000, and new competition has originated from Asia. Being successful requires now more than before, and joint-use of strategies is one option to survive.

A single case study from a Swedish company operating in the telecom manufacturing was conducted. In particular, a Six Sigma project was followed and analyzed during 2002. However, the outcome of the Six Sigma project has been studied in longitudinal manner until 2014.

The Lean Six Sigma strategy ensures flexible, robust, and efficient processes. However, to make them more agile in order to sustain in today's highly competitive environment, something more is required. This could include staff training, strengthening company culture and collaborating with key partners in the supply chain.

This study is limited to large company that usually has a lot of resources and choices where to put the strategic emphasis as well as has level of control of the supply chain operations. The situation could be very different in small and medium-sized companies and thus it may be more difficult to realize the Lean Six Sigma strategy in such environment. On the other hand, the processes in these companies are often less complex.

This research provides guidance on how to manage the Lean Six Sigma strategy in order to ensure more flexible, robust, and efficient processes as well as how to perform a Six Sigma project in Lean environment, in a proper manner.

This research provides guidance to companies regarding the applicability and properties of the Lean Six Sigma strategy. The paper will also serve as a basis for other companies and industries, on how to survive in difficult times.

The purpose of this paper is to understand the success of Lean Six Sigma (LSS) in banking and financial services industry and to develop a structured stakeholders management model for successful LSS project management.

A two-phase methodology is used. Phase 1 establishes the literature to understand two key process improvement methodologies – Lean and Six Sigma and to derive synergies by their combination leading to success in banking and financial services. The literature also helps to recognize the importance of stakeholder management in LSS projects and to understand how it helps in accelerating change in organizations. Phase 2 of the methodology is based on the interviews conducted by 56 global LSS project managers. This is to understand the practical challenges faced by the LSS project managers in banking and financial services tying back to the existing literature.

The paper identifies the possible opportunities for structured stakeholder management across different phases of Define-Measure-Analyze-Improve-Control (DMAIC) project flow. The first of this kind, “Inform-Involve-Influence” model has been developed based on the understanding from literature and conclusions from the interviews conducted. The proposed model highlights the different set of stakeholders involved in LSS projects and their role in the project. The model also helps categorizing the stakeholders based on the DMAIC phases.

The paper is limited to readymade use in banking and financial service environments for LSS projects. However the paper sets a platform for further research to customize the proposed model for other service industries.

The model proposed as part of the paper helps project managers to inform, involve and influence different set of stakeholders at different phases of the DMAIC flow. The model leaves an opportunity for further research and customization for other service industries outside the banking and financial services space like hospitality, government, heath care, etc. Benefits and limitations of the model were presented as part of the paper.

The paper is the original work contributed by the author. Both the survey findings and the model developed are author’s original contribution for both academicians and corporate professionals.

The purpose of this paper is to capture the status of implementation of Six Sigma in various manufacturing industries and also examine the success of the Six Sigma by using different performance indicators.

The methodology of critical review involves the selection and classification of 112 research articles on the implementation of Six Sigma in different manufacturing industries. The selected articles are categorized by the following: articles distribution based on the year of publication, publication database, various journals, contribution of authors, continent, scale of industry, implemented approaches, focused industry, tools and techniques used in phases of Six Sigma methodology, and performance indicators used in Six Sigma implementation. Then after, future scopes of research opportunities are derived based on significant findings.

The literature revealed that: Very few work was undertaken on the implementation of Six Sigma in various manufacturing industries like ceramic, paper, gems and jewelry, cement, furniture, stone, fertilizer, forging, paper and surface treatment industries. Most of the researchers have considered very few performance indicators to identify the improvement after Six Sigma implementation. But, there is no clue regarding overall improvement in different perspectives after the implementation of Six Sigma. The financial indicators, personnel indicators, process indicators and customer indicators are useful to measure the overall improvement after the implementation of Six Sigma in the manufacturing sector.

The study was carried out on the implementation of Six Sigma methodology in various manufacturing industries, and various performance indicators were identified while implementing the Six Sigma methodology. Case studies pertaining to service industries were not covered here.

Very little research has been carried out to measure the overall success of implementing Six Sigma methodology in manufacturing industries. This paper will provide value to students, researchers and practitioners of Six Sigma by providing insight into the implementation of Six Sigma in manufacturing industries.

The purpose of this study is to determine whether there exists employee-client matching at the bottom of the pyramid (BOP) and the most favourable employee-client categorization in terms of employee productivity when serving the BOP market. This is important in a bid to determine how to effectively operate at the BOP given the market’s unique characteristics.

This study uses two methods depending on the research question. First, a one-way analysis of variance (ANOVA) is used to determine the different employee-client categories based on socio-economic status. Second, fixed effects analyses are performed based on these categories to determine the most suitable employee-client category.

The results show the existence of employee-client matching based on similar socio-economic status. However, multivariate testing reveals that the mismatch category, where employees are of higher socioeconomic status than the clients, generates more favourable employee productivity. Moreover, this result may be contingent on the geographical location of the firm.

The findings are important for human resource management particularly the employment strategy of BOP firms. It suggests the need to consider employee profiles and client profiles when deciding which new markets to target.

The paper uses a global database of microfinance institutions as a case of BOP firms to investigate employee-client matching at the bottom of the pyramid.

The purpose of this study is to investigate the aerodynamic characteristics of subsonic jet emanating from corrugated lobed nozzle.

Numerical simulations of subsonic turbulent jets from corrugated lobed nozzles using shear stress transport k-ω turbulence model have been carried out. The analysis was carried out by varying parameters such as lobe length, lobe penetration and lobe count at a Mach number of 0.75. The numerical predictions of axial and radial variation of the mean axial velocity, u′u′ ¯ and v′v′ ¯ have been compared with experimental results of conventional round and chevron nozzles reported in the literature.

The centreline velocity at the exit of the corrugated lobed nozzle was found to be lower than the velocity at the outer edges of the nozzle. The predicted potential core length is lesser than the experimental results of the conventional round nozzle and hence the decay in centreline velocity is faster. The centreline velocity increases with the increase in lobe length and becomes more uniform at the exit. The potential core length increases with the increase in lobe count and decreases with the increase in lobe penetration. The turbulent kinetic energy region is narrower with early appearance of a stronger peak for higher lobe penetration. The centreline velocity degrades much faster in the corrugated nozzle than the chevron nozzle and the peak value of Reynolds stress appears in the vicinity of the nozzle exit.

The corrugated lobed nozzles are used for enhancing mixing without the thrust penalty inducing better acoustic benefits.

The prominent features of the corrugated lobed nozzle were obtained from the extensive study of variation of flow characteristics for different lobe parameters after making comparison with round and chevron nozzle, which paved the way to the utilization of these nozzles for various applications.

This article aims to describe and analyze the results of efforts to improve patient‐centered care (PCC) in psychiatric healthcare.

Using the methodology of a qualitative case study, the authors studied three Swedish child and adolescent psychiatric care (CAP) units in order to describe how patient‐centered actions are performed. They conducted 62 interviews, made 11 half‐day observations, and shadowed employees for two days.

The article shows that the increased focus on accountability for unit performance and medical risks results in unintended consequences. The patient's medical risk is transformed to a personal risk for the psychiatrist and the resource risk is transformed to a personal risk for the unit manager. Patients become risk objects for both psychiatrists and unit managers, which creates an alignment between them to try to send patients elsewhere. New public management (NPM) reforms may consequently lead to the institutionalization of unintended healthcare practices.

The article shows that accountability pressure to reduce patient risk may create new risks for patients.

The study uses theoretical concepts of risk tradeoffs (risk substitution and risk transformation), which were developed for the macro level, to explain the unintended consequences of NPM reforms at the micro level.
