Purpose In recent times, the idea of taking advantage of the benefits of simulation techniques and Six Sigma discipline altogether has led various organizations towards implementation of simulation tools within Six Sigma methodology. The purpose of this study is to provide a more comprehensive literature review on the topic exploring how this amalgamation could work both in theory and practice. This precisely entailed finding dependable studies that shows how Six Sigma (DMAIC) Methodology can be enhanced by the three prevalent simulation techniques; Agent-Based (AB), Discrete-Events (DE), System Dynamics (SD). Design/methodology/approach A systematic literature review was considered more fitting in research because it involves rigorous and well-defined approach compared to other forms of literature review. In this case, the literature was comprehensive, well-encompassing and involved finding Six Sigma and Simulations literatures from reputable scholarly databases. The outcome of these reviews was the identification of a set of key finding compiled and classified by topics. The study follows an inductive approach and utilises a meta-synthesis review technique. Findings As numerous studies assert, simulation techniques including AB, DE and SD are applicable tools in almost every stage of DMAIC, especially the Analyse, Improve and Control phases, because of their capability to test and identify potential bottlenecks and improvement areas. Findings show that the simulation tools such as CLDs, Group Model Building, Dynamic Balance Scorecards and Cost of poor quality all have the potential to add value to a Six Sigma methodology. Originality/value The findings of this study highlight the importance of further inquiry in this area of study. The finding of this study suggests that although the study on the integration of Six Sigma and simulations is increasing, empirical evidence on its effectiveness is still limited. Therefore, this study suggests more roadmaps and investigations aimed at merging Six Sigma methodology and various simulation technique. Moreover, studies that centre on hybrid or multi-method simulations within Six Sigma are also urgently necessitated.

Purpose The purpose of this paper is to illustrate the systematic role played by Six Sigma methodology in improving the quality of healthcare. The literature review identifies the relevant opportunities for successful introduction and development of Six Sigma approach in healthcare sector. Design/methodology/approach A systematic methodology to identifying literature on Six Sigma in healthcare is presented. Web of Science, Medline, Emerald Insight, ASQ and ProQuest databases (1998-2016) were searched, and 68 papers of fair methodological quality were identified. Findings The findings of the systematic review reveal a growing interest in research on Six Sigma adoption in healthcare. The findings indicate that Six Sigma applications in healthcare have been focused on the entire hospital with no real focus on a particular department or function. The key findings on benefits, success factors, challenges and common tools of Six Sigma from the existing literature are also presented in the paper. Research limitations/implications The papers included in the systematic review were peer-reviewed papers available in English. Due to these limitations, relevant papers may have been excluded. Moreover, the authors have excluded all conference and white papers for their inclusion in this study. Originality/value This paper can serve as a guide on how Six Sigma approach can be applied to improve the quality of healthcare. The authors also believe that this is possibly the most comprehensive systematic literature review on the topic and will set the foundation for various research avenues based on the key findings of this study.

PurposeThe purpose of this paper is to capture the evolution and status of utilization of the Six Sigma philosophy in the development of small to medium‐sized enterprises (SMEs), as well as to document prominent development of practices through a systematic literature review.Design/methodology/approachThe methodology adopted for this study used the principles of content analysis and deductive reasoning vis‐à‐vis various sub domains of Six Sigma methodology pertaining to industries in general and SMEs in particular.FindingsThe literature revealed that: Management's commitment is most important in SME Six sigma implementation. Benefits of Six Sigma have been enjoyed largely by the bigger industrial units and to a relatively lesser extent by the smaller units, i.e. SMEs. Quality management culture has largely been ignored or given less importance in the SME sector, which is evident from the meagre literature. There is a dearth of clear and SME‐specific methodologies (for Six Sigma approach) for quality improvement and there are far fewer models for quality improvement in the SME sector.Originality/valueIt has been found, on the basis of a systematic literature review approach (used in this paper), that quality management and development in SMEs needs to be done in a planned manner using Six Sigma roadmap.

Purpose This study aims to expand the current knowledge of the Six Sigma approach in a period of time when there is little direct evidence of the need to improve the credit card account opening process. This is an important but neglected area of focus in the Six Sigma literature. This study explores the extent to which process improvement practices are extended to the credit card department. Design/methodology/approach A case study methodology is adopted in this study to facilitate an exploration of the implemented Six Sigma approach in the credit card department of a leading commercial bank. The process improvement tool used is the define, measure, analyze, improve and control (DMAIC) cycle. Findings The study’s results confirm that the Six Sigma approach improves the quality of the credit card account opening process. So, the Six Sigma approach can account for a reduced number of keying-in errors, resulting in better data accuracy and improved customer satisfaction. Research limitations/implications The authors, in an attempt to render the study results more feasible for data collection, have chosen to focus on the process of the new accounts unit of the credit card department. Therefore, the authors have not taken into account the other units (e.g. transaction processing) of the same department. Practical implications The results of this study will be useful in persuading bank management to evaluate and implement the Six Sigma approach. Hence, this research will assist bank managers with replies to questions, such as: “What impact will Six Sigma have on process-centric improvement, such as the new accounts opening process of a credit card department?” Originality/value Within the literature on the Six Sigma practice, there is little research that focuses on the implementation of this particular toolset especially for credit card departments. This indicates a gap in the field. A new contribution to bridging that gap comes from the analysis of the results for the Six Sigma concept, which addresses the new accounts opening process.

PurposeThis study aimed to identify driving factors of safety attitudinal ambivalence (AA) and explore their influence. Construction workers' intention to act safely can be instable under conflicting information from safety management, co-workers and habitual unsafe behaviour. Existing research explained the mechanism of unsafe behaviours as individual decisions but failed to include AA, as the co-existence of both positive and negative attitude.Design/methodology/approachThis study applied system dynamics to explore factors of construction workers' AA and simulate the process of mitigating the ambivalence for less safety behaviour. Specifically, the group model building approach with eight experts was used to map the causal loop diagram and field questionnaire of 209 construction workers were used to collect empirical data for initiating parameters.FindingsThe group model building identified five direct factors of AA, namely the organisational safety support, important others' safety attitude, emotional arousal, safety production experience and work pressure, with seven feedback paths. The questionnaire survey obtained the initial values of the factors in the SD model, with the average ambivalence at 0.389. The ambivalence between cognitive and affective safety attitude was the highest. Model simulation results indicated that safety experience and work pressure had the most significant effects, and safety experience and positive attitude of co-workers could compensate the pressure from tight schedule and budget.Originality/valueThis study provided a new perspective of the dynamic safety attitude under the co-existence of positive and negative attitude, identified its driving factors and their influencing paths. The group model building approach and field questionnaire surveys were used to provide convincible suggestions for empirical safety management with least and most effective approaches and possible interventions to prevent unsafe behaviour with tight schedule and budget.

PurposeThe paper makes an endeavour to explore the efficacy of service learning (SL) pedagogy in inculcating the value of diversity, equity and inclusion (DEI) with a focus on management education in India.Design/methodology/approachThe research methodology comprises a systematic survey of select relevant literature on SL and applying a novel approach to bring out certain key traits of SL initiatives. The paper also tries to decipher how the identified key traits could be regarded as contributing to the ethos of DEI among the learners. Based on insights from the systematic literature review and identified research gaps, an in-depth study of three SL initiatives in India, have been undertaken to demonstrate how implementation of the SL pedagogy in management education creates an impact on the attributes of DEI and inculcates an inclusive mindset.FindingsAlthough the design, process and learning outcomes of SL pedagogy varies depending on the context, there is commonality in the core attributes that emerges from the literature review which has a potential impact on inculcation of the values of inclusion and appreciation of diversity. The select case studies successfully expand on the list of these identified relevant attributes. The findings have also been corroborated by participants' reflection.Research limitations/implicationsThe paper is, however, limited in its scope of assessing the impact in creating an inclusive mindset. To gauge whether such impact is pervasive and persists in the long run, one needs to examine if these values are carried forward by the participants in their professional and daily life. It would, therefore, be more meaningful to carry out a primary survey of the participants, who took part in such SL initiatives, to understand whether the values have really been assimilated in the real life. This is outside the scope of this paper but does open the scope for further research.Practical implicationsThe paper would be highly relevant for the accreditation agencies who are increasingly prescribing the role that business schools can and should play towards inculcating the ethos of diversity and inclusion among future business leaders and managers. For the administrators of business schools and other higher education institutions who may be considering how to incorporate the ethos of diversity and inclusion in the curriculum and pedagogy, the paper will provide some direction through the SL route. The detailed exposition of the three SL initiatives will enlighten the administrators or the faculty responsible for designing and delivering any SL programme in other business schools or higher educational institutions as to how to go about developing and delivering such an initiative. To the extent such SL initiatives succeed in leaving a lasting impact on the participants regarding ethos of inclusion and diversity, the business implications in the long run could be immense.Social implicationsThe purpose of the paper by itself establishes its social relevance. The very fact that the paper is focused on SL initiatives that involve social problem-solving approaches through hands-on working on social projects and working with communities the social implications are rather obvious.Originality/valueGiven the paucity of information and analysis on potential fit of SL for fostering DEI especially in developing countries, the present paper contributes to the existing body of literature and aptly fills the void. It builds a theoretical construct relating SL with the traits of DEI and then bridges theory and practice by demonstrating the efficacy of three SL programmes in Indian context to internalise the elements of DEI.

Purpose Islamic attributes and activities need to be developed in compliance with the halal concept to attract potential Muslim tourists and ensure the success of halal tourism. Although the literature shows that many factors can influence the success of halal tourism, a complete picture of the success factors of halal tourism in a city is still very limited. As such, this explorative study aims to examine stakeholders’ perspectives regarding the antecedents of halal tourism success and the benefits of halal tourism for the city. Design/methodology/approach Qualitative system dynamics modeling was used for this study, and Makassar (a successful halal tourism city) was considered as the basis for the study. A causal loop diagram (CLD) of halal tourism was developed using the group model building technique to elicit stakeholders’ knowledge and assumptions. Network analysis and feedback loop analysis were used to identify the driving factors of successful halal tourism. Findings Two factors need to be taken into account by halal tourism stakeholders in the city: support from the central and local government and improving and maintaining potential tourists’ perceptions of the city. There are four benefits of halal tourism success for the city: an increase in the number of micro-, small- and medium-sized halal businesses in the city, increased support from the central and local government to further develop halal tourism infrastructure in the city, increased word-of-mouth promotion of Makassar as a tourism destination and a decrease in the price of halal tourism components (e.g. food and accommodation). Originality/value The resulting CLD shows the interlinkage between political, societal and economical factors that could influence the success of halal tourism development. In particular, the findings show how governments and tourism stakeholders need to promote halal tourism socialization in the community and improve the public perception of this type of tourism. Therefore, the findings can help destination stakeholders and tourism developers in other cities develop halal tourism potential.

PurposeWhile placemaking is a multi-disciplinary concern, it is a key focus within the discipline of spatial planning. This paper aims to explore the development of theoretical trends with regard to placemaking in spatial planning since 1975 to identify current emerging theoretical perspectives. Special attention is given to differences in perspectives between the Global North and the Global South.Design/methodology/approachThe study used an integrative literature review (ILR) to analyse placemaking literature over a period of 41 years and five months. The ILR followed the basic review stages: scoping; planning and review protocol; identification/availability; searching; and screening. ILR differs from other reviews as quality appraisal, data gathering, analysis and synthesis rely on coding, thematic content analysis and synthesis.FindingsInitially, the planning/review protocol resulted in 59 contributions on placemaking in various disciplines (excluding publications in other languages that English). Contributions included spatial and design disciplines (29 contributions), social sciences (14 contributions) and other disciplines (16 contributions). The literature review proceeded with a selection of 23 spatial planning contributions (20 from the Global North and three from the Global South). Theoretical trends include placemaking theorised as a physical construct, a social construct, an economic construct (absent in literature from the Global South), a tool for empowerment, a psychological dimension and an environmental management tool.Practical implicationsThe most recent theoretical perspectives in literature suggest placemaking as an enabling tool in which people share knowledge and learn new skills to transform their own environment. This empowering process creates a linkage between planning theory and practice.Originality/valueThis paper contributes to the current theories of placemaking in spatial planning. It provides a simplified view of an exhaustive list of existing literature. This paper reports on the current trends and the development of placemaking theory.

Purpose The purpose of this paper is to use a practical case study approach to demonstrate the power to use lean Six Sigma (LSS) to improve service process in a higher education institution (HEI). The paper also illustrated the barriers and challenges met and lessons learnt for the LSS adoption in this HEI. Design/methodology/approach Prior to the study, extensive literature review was conducted to understand various aspects of LSS in HE industry. The authors use a single descriptive case study as methodology to explain how DMAIC was applied within a HEI environment. Findings In this LSS case study, the team found HEI service process contains a large human behavior component, which dramatically increases the unpredictability of the entire service delivery process and increases the complexity of the process and the ability of the improvement team to identify the root cause. This case study demonstrates the numerous challenges will occur in working with the intangible factors that are both hard to recognize, quantify and rarely tracked by organization. Practical implications During the research, the pre-award service process was studied, data were recorded and various statistical tool and techniques were used to discover and resolve the root cause. The lessons learnt of the LSS adoption in this service process in HEI and the problems encountered were all recorded in this study, which will be helpful for future research in HEI industry. Originality/value From the literature review, LSS has been widely adopted in manufacturing industry, increased adoption in service, but there has been limited academic research about the implementation in nonprofit, service sectors, particular to higher education industry. The major benefit of implementation LSS in both manufacturing and service is considerable improvement to the bottom line. However, in this HEI case study, it has opened up the direction to implement LSS to better serve your customer as ultimate mission instead of financial gains.

Purpose The purpose of this paper is to provide an analysis of the studies about workaround behavior in the Information Systems (IS) area, addressing its positive and negative aspects and raising the key related issues. Design/methodology/approach A systematic literature review was conducted to verify how workaround behavior has been approached in IS studies. A qualitative method was adopted and implemented in two stages: selection of articles from the time period 2007-2017 in the databases Web of Science, ScienceDirect and Scopus and analysis of the selected articles. Findings The results showed that many studies have been concerned with identifying the principal reasons for the manifestation of workaround behavior and the measures taken to reduce its impacts. Many studies from international journals examined the implementation of an ERP along with the workaround behavior. The need to expand the national studies on workaround behavior is emphasized, because the majority of the identified studies are international. Research limitations/implications The key limitation is related to the period of analysis, because only articles published since 2007 were selected. Practical implications This paper contributes to both theory and practice, bringing relevant concepts about workaround behavior, and corroborating the importance of the studies on workaround in the IS area. The literature review of the 20 articles analyzed reveals the main features in each article, such as theoretical and methodological aspects that support the research. Based on this analysis, a conceptual map was developed presenting the most relevant points about workaround behavior, where the causes, the negative and positive consequences, the types of solutions and the organizational and individual impacts are presented. Originality/value Research into workaround behavior has increased in recent years, however very few studies have been conducted in Brazil. To the best of the authors' knowledge, no articles regarding Brazil and this subject were published between 2007 and 2017. Thus, this paper seeks to redress this imbalance.
