This study aims to investigate the production of scaffolds by selective laser sintering (SLS) using poly(vinyl alcohol) (PVA) polymer, for in vitro studies, a relatively new and growing area in which scaffolds could be used in the design of three-dimensional models for in vitro disease model or tissue equivalent for safety and effectiveness tests.

The influence of the SLS process parameters laser power, 26 W and 32 W, and number of laser scans, 1, 2, 4 and 6, on the surface microstructure of the samples and on the degree of crystallinity and chemical stability of PVA material, was investigated using powder with particle size of 20-320 µm. Laser sintered PVA samples were subjected to cell culture tests using osteoblastic cells derived from human osteosarcoma (SaOs-2).

The laser power has no significant influence on the microstructure of the laser-sintered samples, however the number of scans has a considerable influence on the sintering degree; the SLS process causes a decrease in the degree of crystallinity and changes the chemical structure of the as-received PVA, especially when using higher laser power and more number of scans. Preliminary in vitro cell culture tests show that the laser-sintered PVA material is biocompatible with SaOs-2 cells.

SLS offers good potential for the fabrication of scaffolds and thus, may be applied as an alternative to conventional scaffold fabrication processes to overcome their limitations.

This paper aims to analyze the evolution and interaction over time of the functions of a technological innovation system (TIS) based on the concept of an innovation motor.

It is a case study of the innovation system associated with the technology for producing cage-free pullets for laying eggs in Pelotas/Rio Grande do Sul (RS).

The motors proposed by the TIS approach evolve sequentially and are associated with cumulative causality mechanisms. The study's results identified two functionalities: analysis of the chain as a whole and coordination of the actors involved in the system. The study's results also identified the presence of inflection points at the beginning of each of the motors.

The absence of a more accurate detailing of the market motor in discussions of the evolution of the motors and functions of TIS cage free Pelotas.

Innovation Motors as a new guiding approach for participatory innovation initiatives in rural areas.

Application of the TIS approach in agribusiness and proposition of two new functions for motor analysis, in addition to including inflection points as activation triggers in the evolution between motors.

Although the governance and management of networks are deeply intertwined, there is a lack of empirical studies on how strategic networks (SNs) configure both realities for higher performance. This paper aims to analyze the array of governance and management sets adopted by high-performing SNs.

The authors bridge the research gap by using qualitative comparative analysis on the governance (decision-making process, formalization, specialization, incentives and control) and management (strategy, structure, processes and leadership) dimensions of 73 Brazilian SNs.

The authors found that high-performing SNs adopt one of two governance/management configurations. “Piloted SNs” rely on specialized working teams, have structured decision-making processes and avoid using incentives. Conversely, “atomized SNs” run on incentives and control while eschewing specialization and rigid decision-making procedures. The authors also found that both configurations adopt formal procedures and leverage all four management dimensions.

The study’s results offer pathways for SNs to increase their performance and attract new members, as well as insights into the theory of SN governance.

Literature on eco-innovation brings insights that help to understand which factors trigger innovation focused on sustainability in companies. However, when analyzing the studies that comprise such drivers, it appears that most of them were focused only on describing them in isolation. Therefore, this study aims to understand which are the combinations of drivers that favor the adoption of eco-innovation in slaughterhouses located in the Brazilian state of Rio Grande do Sul.

This study has used the crisp-set qualitative comparative analysis (csQCA) as the data analysis technique, in addition to the previous application of Most Similar Different Outcome/Most Different Same Outcome (MSDO/MDSO).

This study identified eight internal and external drivers that explain the differences in performance of eco-innovative and non-innovative slaughterhouses. These drivers generate 13 combinations of factors capable of favoring the adoption of five types of eco-innovation.

A limitation identified was the difficulty to obtain information held by companies on environmental issues. In addition, in each company the authors only approached one respondent.

The use of combinations is identified by companies and governmental and non-governmental organizations to promote eco-innovation in slaughterhouses.

This study may be considered original for its contribution to the improvement of eco-innovation literature by describing how the drivers identified combine to favor the adoption of certain types of eco-innovation. In addition, the authors also made an original use of csQCA, linked with MSDO/MDSO, in the field of eco-innovation.

The main objective of this study is to investigate the 7 new quality control or the 7 new management tools and their use in manufacturing organisations. This research investigates the understanding, knowledge of the tools and the level of application of the tools within the manufacturing sector. In addition, this paper aims to identify the benefits, challenges and critical success factors (CSFs) for the application of the 7 new quality control (QC) tools.

An online survey instrument was developed, and data collection was performed utilising a stratified random sampling strategy. The primary strata/clusters were formed by quality professionals working in all aspects of manufacturing organisations and functions. A total of 86 participants from different countries responded to the survey.

The main finding of this study is that 10% of participants within the manufacturing sector perceived that the 7 new QC tools could solve above 80% of organisational problems. Another relevant finding presented in this paper is that tree diagrams were the most utilised of the 7 new QC tools within the manufacturing sector. The least utilised tools are arrow diagrams. The common benefits of using 7 new QC tools in the manufacturing sector are helping people define, measure and analyse the problem areas or even prioritises them and providing some form of structure to the problem-solving efforts. This paper also revealed that the 7 new QC tools were most used in the manufacturing area but least utilised in the new products and research and development (R&D) functions. This work also presents a list of CSFs and challenges required to properly apply the 7 new QC tools in the manufacturing sector.

This study was just carried out in manufacturing organisations. It would be interesting to try and expand to services sectors and compare use within the services sector.

Authors understand that this is the very first empirical study analysing the use and understanding of the 7 new QC or management tools within the manufacturing sector. The results of this study represent an important first step towards a complete understanding of the applicability of these tools in continuous improvement programs on a global scale and the context in which they can be utilized.

Process improvement initiatives, such as Lean, Six Sigma and Lean Six Sigma, typically have common characteristics that are carried through projects. Whilst a project’s performance is an important determinant of the successful implementation of continuous improvement (CI) initiatives, its failure can undermine the impact of any CI initiative on business performance. As a result, an understanding of the reasons of process improvement project failures is crucial. The purpose of this paper is to present the results of a pilot survey highlighting the most common reasons for process improvement project failures.

This paper presents a pilot survey of 42 Brazilian manufacturing specialists who have been involved in process improvement projects. The participants of this survey were Six Sigma Master Black Belts, Black Belts, Green Belts and Six Sigma champions from manufacturing companies in Brazil. The survey questionnaire was piloted with five experts in the field in order to ensure that the questions were valid and technically sound.

The execution of Six Sigma projects in organizations results in a moderate rate of project failures. These failures can cost organizations several millions of dollars especially within the context of larger organizations. The main reasons for project failure, as cited by the specialists include: resistance to change, lack of commitment and support from top management and incompetent teams.

The authors report the findings from a pilot survey having a limited sample size. Moreover, the data have been collected from one country and primarily from large manufacturing companies.

To the best of the authors’ knowledge, this is the first empirical study looking into the reasons for process improvement project failures. The authors argue that if the top reasons for such failures are understood, a framework can be developed in the future that can mitigate the chance of project failures during project execution. This could potentially lead to significant savings to the bottom-line of many organizations.

The purpose of the article is to present the results of a critical literature review (CLR) on Design of experiments (DoE) in the service industry.

A critical review of existing literature review across various databases including Scopus, Web of Science, Google Scholar and Emerald Insight were searched for the identification of relevant papers. The authors searched relevant journal articles for a time period of 25 years (1994–2019).

A total of 29 industry case studies of DoE applications were identified spanning healthcare, retail, logistics, education, marketing, after sales and catering business. The industrial experimentation strategies adopted by the case study organisations were screening, factorial designs, Taguchi, response surface method and split-plot. It was apparent that there are only a handful number of papers showing the applications of DoE across the service sector and this motivates for pursuing further research into this topic by the authors.

The findings of the study can be very useful for middle and senior managers to understand the benefits of implementing this powerful technique for increased understanding of service processes, as well as for optimising service performance. Moreover, the paper presents some of the fundamental challenges, as well as skills needed for the successful application of DoE.

To the best of our knowledge, this is the first CLR on DoE and its applications in the service sector. The findings of the study can be beneficial to both academic and industrial communities to understand some of the challenges and fundamental gaps which need to be tackled in the future.

The main purpose of this study is to revisit Dr. Ishikawa's statement: “95% of problems in processes can be accomplished using the seven quality control (QC) tools” from his book “What is Quality Control?”. The authors are interested in critically investigating if this statement is still valid nowadays. It involves the analysis of the usage of the seven QC tools in the manufacturing and service sectors and the benefits, challenges and critical success factors (CSFs) for the application of the seven QC tools.

In order to evaluate Kaoru Ishikawa's statement and how valid his statement is for manufacturing and service industries nowadays, an online survey instrument was developed, and data collection was performed utilising a stratified random sampling strategy. The main strata/clusters were formed by senior quality professionals working in operational excellence, quality consultants, quality directors, quality engineers, quality managers and quality supervisors working in both manufacturing and service sectors from South American companies. A total of 97 participants from different countries in South America responded to the survey.

The main finding of this study is that only about 20% of respondents felt that the original seven basic tools of QC can solve above 80% of quality related problems in their businesses. This is quite different from the findings reported by Dr Ishikawa in his work in between 1970 and 1980s. Another relevant finding presented in this paper is that Pareto analysis, histograms and cause and effect analysis are the most used tools in both manufacturing and service sectors. This paper also revealed that the seven QC tools proposed by Dr. Ishikawa were least used by human resources (HR), information technology (IT) and finance functions. This work presents a list of critical success factors required for the proper application of the seven QC tools.

All data collected in the pilot survey came from professionals working for South American companies. So, this paper does present limitations in terms of generalisation of the results. Also, data were collected at an individual level, so parameters such as the inter reliability of judgements on a particular survey item could not be evaluated. It is important to highlight that n = 97 is a low sample size, enough for a preliminary survey but reinforcing the limitation in terms of generalisation of the results.

Authors understand that this is the very first research focused on challenging Dr. Ishikawa's statement: “95% of problems in processes can be accomplished using the seven quality control (QC) tools” from his book “What is Quality Control?”. The results of this study represent an important first step towards a full understanding of the applicability of these tools in manufacturing and service industries in a global scale.

The term Lean Startup (LS) was coined by Eric Ries, and his 2011 book has popularized the concept with organizations, both startups and established organizations, implementing LS. However the empirical grounding is thin and for a long time this subject has been neglected by academia. The purpose of this paper is to present a systematic literature review (SLR) on LS, while highlighting core knowledge and identify gaps.

A SLR was carried out based on the Preferred Reporting for Systematic Reviews and Meta-Analyses (PRISMA) protocol of Scopus and Web of Science databases. In total, 45 articles published in journals and conferences over 10 years were collected which revealed a number of LS research gaps.

The SLR revealed the tools and methods associated with LS, most cited pros and cons, reasons that cause LS failure, the challenges that companies face in the implementation of LS, and critical success factors (CSFs) that can support these challenges and minimize the reasons for failure.

The findings of the study can be beneficial to practitioners and senior managers in organizations who wish to delve into the journey of LS. The study also discloses challenges and barriers that can hinder the implementation of LS.

Academic publications regarding LS are sparse and this SLR is one of the first SLRs to explore both the critical failure factors (CFFs) and the CSFs based on peer-reviewed journal and conference proceedings.

The purpose of this study is to critically evaluate the current status of Design of experiments (DoE) in the service industry or non-manufacturing processes in the manufacturing sector. This involves the identification of critical success factors and challenges in the use of DoE in the context of the service industry as well as the key skills needed for its successful applications.

In order to identify the critical success factors and challenges, an online survey instrument was developed and distributed across Six Sigma Black Belts (SSBB), Six Sigma Master Black Belts (SSMBB), process improvement champions, continuous improvement professionals, DoE experts and specialists as well as academics who are involved in DoE research and applications.

A total of 109 participants from over 20 countries responded to the study. One of the first findings of the study is that over 40% of the process improvement professionals in the service sector do not have any hands-on experience with the application of DoE. Further, this study highlights the following critical factors for successful DoE applications: dedicating adequate resources in terms of time, budget and people for the experiment; getting a clear understanding of the problem at hand; securing a reliable and validated measurement system for measuring the response or quality characteristics of interest; and identifying input independent variables, which influence the quality characteristics during the brainstorming stage. Some respondents also mention the importance of having training or education in DoE as a critical success factor. At the same time, the lack of adequate planning to experimentation, mathematical knowledge and statistical reasoning remains as challenge to be solved.

As data were collected at an individual level, inter-reliability, which measures the consistency of judgements on a particular survey item, could not be gauged. Moreover, due to low sample size across some continents, an intercontinental comparative study on the extent of the application of DoE across various continents could not be performed.

To the best of the authors’ knowledge, this is the first global survey carried out to understand the status of DoE in the service industry. The results of the global study can be used to encourage quality, continuous improvement and process improvement professionals in the service sector to drive wider acceptance of one of the most powerful tools in the Six Sigma toolkit for problem-solving scenarios. Moreover, senior managers in the service industry can take away some of the key benefits, challenges and success factors in the implementation of DoE.
