This paper aims to present a lean management approach to reduce waste generated by overproduction within a global supply chain setting. Statistics register a considerable increase in inventories which has increased waste because of the overproduction/oversupply throughout the global supply chain, and there has been insufficient research targeting on it.

This study develops a conceptual approach based on the practices of Toyota Production System (TPS). The analysis is performed on four segments of a business: “R&D”, “Production”, “Logistics” and “Service/retailers”. The proposed approach adopts the pull-based lean management system by two modules, “Intra-lean management” and “Inter-lean management”.

A case study is conducted to demonstrate how the proposed approach can be used in a real situation. The ideas and benefits of the proposed approach are also discussed.

The proposed solution can be applied in manufacturing and service industries, as well as in industries where production and R&D are interconnected.

The paper provides a conceptual approach that explains how intra- and inter-lean management can be effectively integrated to achieve a smooth flow in the business. This paper innovates in developing a pull-based driven flow relationship among the four segments of a business, as a response to the lack of integration among them and the increase of inventory in the hands of businesses.

This paper aims to review total quality management (TQM) literature in the past three decades to identify the quality related key terms, to analyse their linkage among the identified key terms and their developmental trends.

Bibliometric and statistical methods are used to analyse article titles published in the Total Quality Management and Business Excellence journal during 1990–2019. The current research is based on a search from the ProQuest academic database and the journal’s website, resulting in 2,452 articles collected. The VOSviewer and Microsoft Excel were then used for the analyses.

A total of 52 key terms were extracted from the journal’s 2,452 article titles, the top three key terms in terms of occurrences were “quality,” “total quality management” and “service quality.” Five themes were then proposed from clustering the 52 key terms: “frameworks/models,” “essentials/enablers,” “methods/techniques,” “culture/characteristics” and “effects/results.” Trend analyses were also conducted regarding the five themes in an attempt to highlight the patterns of research publications from 1990 to 2019. It is found that the research publications for “essentials/enablers,” “methods and techniques” and “effects/results” have steadily increased during the analysis period, while “frameworks/models” and “culture/characteristic” have slightly decreased. These insights provide implication for the historical evolution of quality from “quality control,” “total quality management” and “service quality,” combining with the development of “service sciences.”

This paper highlights the concept of quality since its meaning has changed and evolved over time from quality control, TQM to service quality. And it is emerging in the present and future development of service sciences because of both of TQM and service sciences having the same nature of multidisciplinary background and characteristics. Also the authors can conclude that quality and service sciences are in fact two sides of the same coin because both of them having the same duality of “tangible-intangible” and “physical-virtual” faces which are the important topics that TQM should focus on.

The purpose of this paper is to develop a greenhouse gas (GHG) management model for mitigating GHG emission. GHG emission by way of human activities is causing catastrophic effects on the natural environment in the form of climate change and global warming. GHG management of different products, bodies and processes is going on worldwide, expressed through carbon footprints by using product life cycle assessment (LCA). LCA is a useful approach, but it only looks at the micro level of cause-effect scenarios rather than the macro level cause-effect scenarios of GHG emission. Therefore, a system to scrutinize underlined assumptions and values of such policies/strategies is an urgent necessity.

This paper uses the double-loop learning concept, which was proposed by Argyris in 1976, to develop a triple cause-effect model for the management of GHG emission. The proposed model has a knowledge system that introduces the learning loop of GHG emission and environmental impact management.

A case study is conducted to demonstrate how the proposed triple cause-effect model is operationalized. The ideas and benefits of the proposed model are further discussed.

A triple cause-effect model for the measurement and analysis of GHG emission is proposed in this paper to complement GHG management by using only product LCA. This paper seeks to show that GHG management should look at not only a single tree (product LCA approach) but also the whole forest (the proposed model).

Increasing the service quality in administrative areas is a critical factor facing the service industry today. This is supported by the latest version of the international quality standard ISO 9001, which emphasizes that customer satisfaction should have a complete and objective evaluation method and index. Uses the service quality defect concept in the PZB model to measure the time characteristic of service quality in processing an administrative job. At the same time, establishes the best estimates of service efficiency for each service unit and the whole department. Establishes a non‐center t distribution and a test procedure by p‐value to evaluate if the service process fits the customer‐defined service efficiency index. The result can then be used to judge the service efficiency of both individual service units and the whole department. According to the test procedures presented here, provides an objective evaluation criterion for administration and service industry.

This paper develops a customer‐oriented service model for the public sector. Although customer‐oriented service models have become popular since 1980, most studies have been restricted to the private sector. In addition, they have emphasised the management of service operations rather than system design. This paper proposes a customer‐oriented service‐enhancement system (COSES) for the public sector. The model employs two dimensions: design and management of a customer‐oriented service system; and the fostering of organizational service culture. In this COSES model, the best practices of public agencies are empirically examined with respect to: the types of customer‐oriented service activities that can be developed; and how they can be developed.

The purpose of this paper is to explore existing and desired methodologies for systematic quality work to promote quality in preschools from the principal’s perspective.

A collaborative approach was used in this research project, and principals were asked to complete portfolio assignments. Their answers to those portfolio assignments were analysed by the research team and subsequently compared to total quality management values.

Existing and desired methodologies for systematic quality work are presented and sorted into 13 and 17 groups, respectively. The principals desire four times more methodologies than they are presently using to promote systematic quality work, and the results show that they must extend their methodologies to support TQM values.

This research is based on answers collected from 18 principals in one municipality in Sweden.

The use of the cornerstone model provides a framework to illustrate the application of TQM in preschools.

Principals struggle to find time for systemic quality work. The presented results can be used to work systematically with quality in preschools and other organizations.

The purpose of the present study is to measure the level of public service quality in a unique body of service provision, namely the Citizen's Service Centers (CSCs) of Greece. CSC is a public service organization created in 2002, aiming at providing assistance to all citizens and reducing the bureaucracy of the Greek public administration. Moreover, the present study aims to underline the importance of citizen participation in service planning and provision processes, thus providing an additional dimension to the “New Public Management” (NPM) discipline that has recently found itself under serious critique.

The present study utilized a slightly modified SERVQUAL instrument that was distributed to citizens visiting a representative sample of CSC branches. More specifically, 221 CSCs were visited by the members of the research team (20.35 per cent of the total population) and 843 usable questionnaires were collected from citizens. Random sampling techniques were used in order to acquire a representative and reliable sample.

In brief, it is found that, although citizen expectations are not met in three of the five SERVQUAL dimensions, the overall service quality performance is well above average, allowing one to claim that CSCs have achieved their initial target. The gap scores for the dimensions of empathy and responsiveness were positive, while the same scores for the dimensions of tangibles, reliability and assurance were negative.

The use of the SERVQUAL instrument has been a subject of critique by various authors. Its ability to measure service quality has been supported by many and disputed by few. The present study analytically examined the validity and reliability of the instrument, so as to ensure that its use successfully fits the public service environment.

The paper makes an analytical effort in order to point out areas that managers and policy makers should emphasize in order to increase the level of public services. Certain practical implications are offered in the final part of the paper.

CSCs are, according to the best of the researchers’ knowledge, a worldwide innovation only implemented in Greece. Hence, their examination may serve as a guiding light for other countries suffering from public sector inefficiencies. The methodological contribution of the paper lies in the implementation of the SERVQUAL instrument in the context of public services and its subsequent validation with the use of exploratory and confirmatory factor analysis. On a theoretical level, the present paper enhances the current literature with a paper that argues that citizens should actively participate in the processes of service planning and service provision.
