A rich agenda for future research in the field of Lean Manufacturing (LM) is available in the academic literature. The purpose of this paper is to determine the LM future research methodologies suggested in the literature and to classify them into themes. Classifying these themes into broad categories is also an aim of the present study.

For the purpose of the present study, a systematic literature review (SLR) of peer reviewed journal articles in LM was conducted. A total of 214 articles published in 46 journals during 2010–2020 were collected from four major management science publishers, namely, Emerald Online, Elsevier/Science Direct, Springer Link and Taylor and Francis. To organize the qualitative data into meaningful themes and these themes into broad categories, the quality tool “affinity diagram” was applied.

The review of LM articles that are increasing over time reveals the “vital few” academic journals, which have published most of the sample articles. The plethora of the suggested future research methodologies are analytically presented and classified into meaningful themes, namely, the size of the research sample and its composition, several types of study (other than surveys), longitudinal studies, applying advanced statistical analysis and (mathematical) modeling techniques, objective, real and quantitative data, surveys, mixed/multiple research studies, reliability and validity analysis, using computer-aided technology for data collection and processing and research collaborations. These themes in turn are classified into broad categories, namely, study, data and statistical analysis and modeling.

This SLR is not comprehensive because the number of the databases searched is restricted to four. Moreover, the literature review is limited to peer reviewed journal articles regarding Lean only in the manufacturing sector, while the subject reviewed is limited to the future research methodologies. The subjectivity of classifying the large number of the future research methodologies into themes and these themes into broad categories is also a limitation of the present SLR. Based on these limitations, future literature review studies can be carried out.

Researchers can be analytically informed about the future research methodologies suggested in the literature and their respective key themes and broad categories, to design original research studies of high academic and practical value.

This study goes beyond previous SLRs on LM by presenting analytically the plethora of the future research methodologies suggested in the literature as well as by identifying natural patterns or groupings of these methodologies.

Many future research proposals of Lean Manufacturing (LM) are presented in the literature. The purpose of this paper is to determine these future research proposals of LM which are country-related and classify them.

A systematic literature review (SLR) of peer-reviewed journal articles in LM was conducted. A total of 145 articles published in 34 journals during 2010–2020 were collected from four major management science publishers namely, Emerald Online, Elsevier/Science Direct, Springer Link and Taylor and Francis. The country-related future research proposals of LM identified in the literature were classified according to, firstly, the continent of the country of reference, and secondly, some form of natural affinity of these proposals creating meaningful themes. The quality tool “affinity diagram” was applied to classify the country-related future research proposals of LM.

The country-related future research proposals of LM, which are increasing in the literature over time, refer mostly to studies to be conducted in several continents/countries and to multinational studies. Conducting studies specifically in Asia, Europe, South and North America, Africa and Australia–New Zealand is also suggested. The plethora of the country-related future research proposals of LM were classified, based on the affinity of their content, into 18 meaningful themes. These themes were also classified based on their affinity into two broad categories, namely “themes concerning the LM approach itself” and “themes concerning factors outside the LM approach”.

The restricted number of the databases searched and the subjectivity of classifying the large number of the country-related future research proposals into themes are the main limitations of the present SLR. Based on these limitations, future literature review studies can be carried out.

Useful proposals are provided to researchers of several countries for conducting original and country-specific research studies which can enrich the knowledge of the implementation of LM under the specific circumstances of a country for the benefit of practitioners.

This study goes beyond previous literature review studies on LM by focusing exclusively on the LM future research agenda which is country related. The analytical presentation of the country-related future research proposals as well as the formulation of clusters of these proposals make the present SLR study substantially different from those carried out worldwide so far.

The purpose of this paper is to identify the future research suggestions which have been made by several authors with regard to cost of quality (CoQ) and to group them into respective themes.

This study was based on a systematic literature review (SLR) of 97 peer-reviewed journal articles in the field of CoQ published in well-known academic databases, such as Emerald, Elsevier, SpringerLink, Taylor & Francis, Wiley and Scopus. The time horizon for reviewing the literature was 9 years, particularly in the period between 2010 and 2018. The “Affinity diagram” was applied to group the future research suggestions into logical themes and the “Pareto diagram” to further categorize and prioritize these themes.

A plethora of future research suggestions identified in the literature are analytically presented. Moreover, the analysis showed that the future research suggestions in the field of CoQ can be grouped under eleven meaningful themes, which are further categorized into two broad categories, meaning the vital and the useful.

This SLR was based on only fully accessed English articles published in international, peer-reviewed journals of the selected publishers. The restricted number of keywords used and the subjectivity in applying the “affinity diagram” are also limitations of this study.

This paper provides insights into the future research perspectives in the field of CoQ. Thus, this analysis can serve as a resource for both researchers and practitioners to further develop this area according to the future research suggestions and the respective themes revealed.

To the best of the authors' knowledge, this is the first SLR presenting and analyzing the future research suggestions of CoQ.

Given that the literature in terms of business ambidexterity is continually growing, the of this paper is to identify the future research suggestions made by several authors with regard to ambidexterity and to group them into meaningful themes.

A systematic literature review (SLR) of peer reviewed journal articles in the field of ambidexterity was conducted. A total of 128 relevant articles were selected, which were published in 58 journals over the past 2 decades (2000–2021).

The plethora of the future research suggestions made by several authors with regard to ambidexterity are analytically presented. Moreover, based on these suggestions, meaningful future research themes were revealed and these were further classified into three broad categories, namely “factors influencing the adoption of ambidexterity and its success”, “the types of ambidexterity” and “the effects of ambidexterity”.

The subjectivity of grouping the future research suggestions into themes as well as not examining the interrelationships among these themes, are limitations of the present study. Based on these limitations, future literature review studies can be conducted.

As this is a SLR focusing on developing future ambidexterity research themes, there are no direct practitioner implications. However, practitioners may benefit from future research prompted by this SLR.

This study contributes to management literature by suggesting future research not only on organizational ambidexterity like previous studies, but also on four different approaches to ambidexterity.

The financial industry offers a unique setting to study innovations. Financial innovations have fueled the growth of economies, markets and societies. The financial industry has successfully become the breeding ground for innovative services, processes, business models and technologies. This study seeks to provide a holistic view of the literature on financial innovations, synthesize the research findings and offer future directions for research in light of three market developments that are disrupting the industry and opening up a new era for the financial services industry. Disruptions from within and outside the industry offer new generations of radically innovative services. Moreover, new generations of consumers differ from previous generations in their needs and wants and look for innovative ways to handle their financial needs. Finally, significant developments related to financial innovations have emerged in Asia and developing countries.

This study systematically reviews the academic research literature on financial innovations in two phases. The first phase provides a quantitative review of 546 journal articles published between 1990 and 2018. In the second phase, the study synthesizes the extant research on financial innovations and maps them in five research areas: firms' introduction and adoption of FIs, financial innovation development, the outcomes of financial innovations, regulations and intellectual property, and consumers.

The analysis found that disciplines differ with regard to the employed research methodologies, the units of analysis, sources of data and the innovations they examined. A positive trend in the number of published articles during this period is observed. However, studies have primarily focused on the USA and Europe and less so on other parts of the world. The literature synthesis further identifies research gaps in the available research that highlight future research opportunities in light of the three market disruptions. The financial services industry is on the brink of a new era due to disruptions from within and outside the industry and the entrance of new generations of consumers. Moreover, the financial industry has successfully become the breeding ground for innovative services, processes and business models. Therefore, financial innovations offer promising opportunities for bridging the gap between research on product and service innovations.

The work provides a holistic and systematic overview of extant research on financial innovations and highlights future research opportunities in light of the three disruptive market developments. It helps researchers take advantage of the opportunities in studying financial innovations while maintaining industry relevance.

The study is the first to review and synthesize the academic research literature on financial innovations across marketing, finance and innovation disciplines. In addition, the study highlights three primary disruptive forces in the financial industry and identifies future research directions in light of these disruptive forces.

To identify what scholars consider to be important and interesting for future research in social entrepreneurship (SE), this chapter analyzes 248 SE papers and generated 327 topics for future research. From these 327 topics, a modified Delphi process generated 27 underlying themes. Subject matter experts were surveyed as to how interesting each research topic is and the extent to which the topics lend themselves to theoretical or empirical development; this assessment was also used to calculate aggregate scores for each theme. In this chapter, we present all research topics that scored at or above 2.5 on a 5-point scale for both questions. We discuss the implications of both the method and the results of the study.

The duration of an innovation process, from new idea to new business, may take many years. This makes it necessary to incorporate a vision of the future. The Cyclic Innovation Model (CIM) shows that aspects such as multiplicity (looking at multi-fold futures) and multidimensionality (looking at different aspects of the future) should be taken into account. Looking at the different actors involved in CIM, the future should be researched with an open mind (meaning that the transition path to the future should be kept wide open) and different time horizons should be taken into account.

This study aims to answer the following research question: What are the opportunities for future research concerning the Frugal Innovation (FI) phenomenon? To address this, the authors propose a novel approach to literature review on the topic. They do so in view of synthesising scholars’ recommendations for subsequent studies. They also advocate that it is time to contribute to the establishment of the FI field by mapping the future of this approach.

The authors conducted a systematic literature review (SLR) to connect past and future research on FI. After the screening process of the documents extracted from multiple databases, they performed a bibliometric analysis to provide an overview of the field. Furthermore, the lexical analysis and descending hierarchical analysis were generated through the IRAMUTEQ software to identify the clusters for future research on FI.

This research not only demonstrates the current state of the art of FI literature but also identifies a research agenda with six categories of opportunities for further studies on the topic: frugal consumer behaviour; establishment of the field; sustainable impact; approaches to different contexts; implementation processes; and challenges for value creation.

The FI phenomenon is receiving increasing attention from scholars in the management field due to its socioeconomic and managerial implications, especially after the Covid-19 outbreak. Therefore, the findings benefit scholars striving to expand the scope of FI research, as well as entrepreneurs, managers and organisations aiming to enhance their social responsibility to reduce their environmental impact.

Virtually all contemporary scientific papers studying careers emphasize its changing nature. Indeed, careers have been changing during recent decades, for example becoming more complex and unpredictable. Furthermore, hallmarks of the new career – such as individual agency – are clearly increasing in importance in today’s labor market. This led the authors to ask the question of whether these changes are actually visible in the topics that career scholars research. In other words, the purpose of this paper is to discover the trending topics in careers.

To achieve this goal, the authors analyzed all published papers from four core career journals (i.e. Career Development International, Career Development Quarterly, Journal of Career Assessment, and Journal of Career Development) between 2012 and 2016. Using a five-step procedure involving three researchers, the authors formulated the 16 most trending topics.

Some traditional career topics are still quite popular today (e.g. career success as the #1 trending topic), whereas other topics have emerged during recent years (e.g. employability as the #3 trending topic). In addition, some topics that are closely related to career research – such as unemployment and job search – surprisingly turned out not to be a trending topic.

In reviewing all published papers in CDI, CDQ, JCA, and JCD between 2012 and 2016, the authors provide a unique overview of currently trending topics, and the authors compare this to the overall discourse on careers. In addition, the authors formulate key questions for future research.

This paper synthesizes the extant research on the outcome effect in the accounting domain, focusing primarily on the context of performance evaluation. It reviews the current state of our knowledge about this phenomenon, including its underlying cognitive and motivational causes, the contexts in which the outcome effect is observed, the factors that influence its various manifestations, and ways in which undesirable outcome effects can be mitigated. It also considers various perspectives about the extent to which outcome effects represent undesirable judgmental bias, and whether this distinction is necessary to motivate research on this topic. The paper is intended to motivate and facilitate future research into the effects of outcome knowledge on judgment in the accounting context. Therefore, we also identify important unanswered questions and discuss opportunities for future research throughout the paper. These include additional consideration of instances in which the outcome effect is reflective of bias, how this bias can be effectively mitigated, ways in which outcome information influences judgment (regardless of whether this influence is considered normative), and how the underlying causes of the outcome effect operate singly and jointly to bring about the outcome effect. We also consider ways that future research can contribute to practice by determining how to encourage evaluators to retain and incorporate the relevant information conveyed by outcomes, while avoiding the inappropriate use of outcome information, and by enhancing external validity to increase the generalizability of experimental results to scenarios frequently encountered in practice.
