Purpose: The changes brought forth by the Digital Transformation have an impact on the way we think, assess and manage Quality. While the concept of Quality 4.0 has resulted from these changes, there is still limited understanding and unclear definitions in this new era of Quality Management.Design/methodology/approach: There is a clear opportunity to review and analyze the state-of-the-art of Quality 4.0, its main research efforts, topics and directions. To do so, a bibliometric analysis and descriptive/mapping literature review were performed.Findings: There is a clear focus on the implications of technology for Quality, but other relevant topics include business management and strategy models and systems, as well as human or soft factors. Results reveal an increasing interest in Quality 4.0 as well as a link between topics.Originality/value: Together with the review, analysis and digest of the literature, we offer our own contribution to a commonly accepted definition Quality 4.0.

In an increasingly dynamic environment where change seems to be the only constant feature, operational excellence programmes are often used to achieve improved performance results. However, the capacity of such approaches to make organisations successful in the long term is yet to be demonstrated. Operational excellence should not be seen as an approach to promote change, but rather to provide tools and framing for people in the organisation to deal with it. Our literature-based theory is that the relationships of operational excellence with both organisational culture and agility have the potential for further integration in the promotion of long-term, sustainable operational excellence initiatives. To do so, such initiatives need to look beyond simple cultural fit and work to promote a more agile behaviour and a cultural capacity to deal with constant change. If these conditions are met, the sustainability of operational excellence should be achieved, with organisations being able to strive in the long term with the promotion of organisational agility capabilities and an adaptable culture. The objective of this paper is to sustain this theory building, proposing the research questions that will help us understand the relationships and integration between the concepts of operational excellence, organisational agility and organisational culture.

Purpose: – The purpose of this paper is to explore the concept of supply chain quality management (SCQM) and to propose a research model that considers the impact of SCQM practices on firm performance. Design/methodology/approach: – Based on a comprehensive literature review, SCQM most relevant practices were analyzed and selected. These practices were categorized into four dimensions: upstream (supplier assessment, supplier quality management (QM)), downstream sides of a supply chain (customer focus), internal process (product/service design, process management and logistics) and support practices (top management support, human resource management, information and supply chain integration). The measurement instrument of firm performance was also developed, including three aspects: operational performance, customer satisfaction and financial performance. Findings: – An innovative conceptual framework that provides a comprehensive picture covering core dimensions of SCQM and various aspects of firm performance was proposed. This conceptual framework can be used as “a guideline” for theory building and measurement instrument development of SCQM and firm performance. More importantly, on the road to gain a further insight, an extensive structural model that identifies direct and indirect relationships between SCQM and firm performance was also developed. Practitioners/managers can apply this model as “a road map” for implementing SCQM practices. Research limitations/implications: – It is necessary to test the rationality of these models by using empirical studies in different contexts. Originality/value: – The integration of quality and supply chain management still remains limited in the literature. Therefore, it is necessary to have a more focussed approach in assessing QM issues within the internal and external supply chain contexts. This study concentrates on the practices which improve quality aspects of the supply chain, known as SCQM practices. Proposed research models in this paper not only fill out the voids in the literature, but also contribute with conceptual frameworks for theory building in SCQM and firm performance. The authors also expect that this research can offer a useful guidance for measuring and implementing SCQM practices as well as facilitate further studies in this field.

Purpose: The purpose of this paper is to provide an empirical evidence about the relationship between practices of supply chain management (SCM) and operational performance (OP).Design/methodology/approach: Based on a comprehensive literature review, a set of SCM practices has been identified and selected to develop a conceptual model as well as to establish their relationship to companies’ OP. The measurement scales of the practices were developed in four steps: identification and development of initial instrument; personal interviews and Q-sort; large-scale data collection; and large-scale analysis in order to ensure unidimensionality, reliability and validity. Structural equation modeling was used to validate the model with the data were collected in Vietnamese garment enterprises.Findings: The study consolidated relationships between the SCM practices and OP. According to the research results, these practices have a “resonant” influence on OP that can explain 52.6 percent variance of this output concept. In particular, customer focus and supplier management both direct and indirect impact on OP while top management support and process control/improvement only have indirect and direct influences on OP, respectively.Research limitations/implications: There are some limitations that can guide academics to new lines of future research: to extend the scope of the survey to include different countries and new situations, so results can be generalized; to consider the impacts of the SCM practices on the entire supply chain performance; and to explore additional factors that can further explain OP, such as operational environment, capital, technology, human resource, etc.Practical implications: The authors suggest that the SCM practices should be implemented as an integrated system rather than independent practices, in which they interact with each other and improve OP.Originality/value: The empirical results of this study provide an evidence to consider the SCM practices as reliable predictors for OP. According to the research, these practices interact with each other and have both direct and indirect effects on OP. In other words, through the mutual interaction among the SCM practices, they have the “resonant” influence on improving OP. Moreover, the proposed research model analyzing the relationship among SCM practices and OP and its validation using the Vietnam garment industry provided valuable insights both from theoretical and practical perspectives.
