Purpose The purpose of this paper is to review the existing literature on Lean Six Sigma (LSS) for services, construct a morphological analysis (MA) framework and identify research gaps to point to future research possibilities and priorities. Design/methodology/approach The MA framework is based on literature review of 175 papers published from 2003 to 2015, across 67 journals recognised by Scopus or ABS Academic Journal Quality Guide 2015. A three-phased methodology is used by the authors, with Phase1 featuring a five-stage systematic review protocol to identify relevant journal papers for review; Phase2 presenting a framework for classifying the reviewed papers in terms of their fundamental, methodological, chronological and sector-wise orientations; and Phase3 constructing an MA framework on the classified papers and identifying the research gaps. Findings The MA framework constructed based on six dimensions, namely, organizational context of applications, desired outcomes, implementation systems, LSS tools and techniques, integration with other management philosophies and evaluation methods, involving 40 focused themes, has revealed 355 distinct research gaps as opportunities for future research. Practical implications This paper confirms the existence of substantial scope and points to specific topics for further research in the area of LSS for services. The findings demonstrate the gaps in academic research on the subject. In addition, the study also helps organisational leaders and practitioners to look at LSS from a holistic perspective in the services context. Originality/value The MA framework of the existing literature on LSS for services presents a unique, systematic effort to identify research opportunities. In addition, a five-stage systematic review protocol is proposed in this paper. This could be valuable to researchers and practitioners in enabling them to systematically review the literature on research subjects of interest to them.

The geometric Brownian motion (GBM) process is frequently invoked as a model for such diverse quantities as stock prices, natural resource prices and the growth in demand for products or services. We discuss a process for checking whether a given time series follows the GBM process. Methods to remove seasonal variation from such a time series are also analyzed. Of four industries studied, the historical time series for usage of established services meet the criteria for a GBM; however, the data for growth of emergent services do not.

We conducted a content analysis on 203 comparative print advertisements in India. We found that as hypothesized, direct comparative advertisements were used more (vis-à-vis indirect ones), differentiative claims were used more (vis-à-vis associative ones), maximal claims were higher than minimal claims, multibrand comparisons were greater in number (vis-à-vis single-brand comparisons), positive valence is preferred to negative valence, and underdog brands used more comparative advertisements than top-dog brands. Contrary to expectations, we found that hedonic and utilitarian products used comparative advertisements equally. We offer a snapshot of the state of comparative advertisements in India that would be useful to managers and researchers.

Purpose The growth, diversity and applications of research into dynamic capabilities (DCs) have resulted in the whole literature on DCs becoming a complex and disconnected body of knowledge. This has led to criticisms of the subject of DCs as being vague, tautological and without practical value. Hence, the purpose of this paper is to synthesize the diverse scholarly literature about DCs and develop a more integrated understanding to minimize the reported apparent vagueness. Design/methodology/approach In this paper, the authors review various relevant themes on DCs using a selection of 133 articles published in 22 recognized, top-tier management journals during the period between 1990 and 2016, with an aim to build a structured and integrated theory. For this, morphological analysis (MA), a systems-thinking technique, is applied. Findings MA is applied to develop a multi-dimensional conceptual framework comprising five dimensions and 26 variants that enable a structured representation of the conceptual foundations of DCs. Further, the authors identify 81 individual DCs noted by various scholars; elucidate assumptions and antecedents relevant to the DCs approach; structure the key characteristics; and expound the input factors, impacting factors, desired outcomes and assessment yardsticks. Research limitations/implications This would be a useful resource for researchers working in the area of DCs to explore opportunities for future research. Practical implications The MA framework helps managers to look at DCs more holistically, and hence would help them in developing, managing and retaining DCs in organizations. Originality/value This study is the original work contributed by the authors and has no specific organizational reference. This research implies new directions to look beyond individual DCs in firms toward a more integrated theory building.

Purpose The evolution of Lean Six Sigma (LSS) within the operations management theory has enjoyed significant success in both manufacturing and services. Though the applicability of LSS is evident in the services sector through various publications, academic research on the use of LSS in the Banking and Financial Services (BFS) is limited, and hence deserves greater attention. The purpose of this paper is to illustrate the application of LSS in consumer banking in real-time setting. Design/methodology/approach A case study method is used to study the application of LSS in two consumer banks with stage 1 featuring identification of appropriate consumer banks where LSS projects could be undertaken, and suitable LSS readiness assessment was performed. In stage 2, LSS project opportunities were identified in the select banks through stakeholder engagement. Finally, in stage 3, LSS projects were executed for process improvements in a real-time setting. Findings The case studies provide evidence of the successful application of LSS in consumer banking and the associated multiple benefits. The extent of applicability and appropriate managerial implications in project management context are elaborated. An LSS project selection criterion is recommended as a part of the study. Further, the study explains five important managerial implications in BFS context, with an outlook for future research. Research limitations/implications Practitioner research shows that BFS organizations have changed their ways of working by adapting LSS over the last decade. However, the academic research concerning the applicability of LSS in BFS is apparently limited, and none of these are specific to “consumer banking.” This study serves as a strong foundation for future research in this area, which is at its nascence and upcoming in the researchers’ community. However, strong generalizations should not be made as this study is limited to two cases. Practical implications Since the cases are executed in the real-time setup of consumer banks, the paper has several practical implications. First, the paper confirms the applicability of LSS in consumer banking and concludes that LSS project management is merely a sub-set of LSS deployment. Second, LSS needs to be understood using a “systems thinking” perspective in order to move away from a narrow project-only approach. An LSS project selection criterion is recommended as a part of the study, which could serve as a managerial resource. Other managerial implications include effective management of stakeholders and change leadership as essential elements of LSS project management in banks. Originality/value LSS has been successful in the past few decades in the manufacturing and service sectors. However, its application in BFS is limited. This study illustrates the applicability of LSS in consumer banks, which deals with high volumes of data, customer bases and associated financial transactions.
