Abstract

Purpose

This paper aims to examine the relationship between supply chain quality management practices and their impact on supply chain performance. The authors define and operationalize supply chain quality management practices that enhance knowledge creation and learning in a supply chain.

Design/methodology/approach

Data are collected from logistics and supply chain managers in the USA to examine the validity and reliability of the model for supply chain quality.

Findings

The empirical result provides support for the reliability and validity of the proposed model, the constructs used in the model, and the interrelationships among key constructs of supply chain quality. The authors show that trust is the main predictor of supply chain quality practices and supply chain quality performance outcomes. In addition, the findings show that the impact of trust on process improvement is mediated by information sharing, inter-firm trust and information sharing are significant predictors of supply chain satisfaction, and inter-firm trust and process improvement are significant predictors of supply chain performance. Implications of the research for the theory and practice of supply chain management and quality management are presented.

Practical implications

This study provides important insights into effective implementation of quality management across the supply chain. Supply chain managers should realize that achieving improvement in many supply chain activities such as information sharing or process improvement requires organizations to be engaged in trust-based activities. In that regard, it is important for supply chain managers to be engaged in developing relationships with their supply chain partners that enhance inter-organizational trust.

Originality/value

This is the first study that examines a supply chain quality management model from the learning perspective. The authors validate the supply chain quality framework proposed by Parast (2103) through operationalization of the constructs, development of the relationship among key supply chain quality practices and empirical assessment of the structural model for supply chain quality.

Abstract

Purpose

In this paper, the authors draw from the concept of a “focused factory” to examine whether a focused strategy provides superior performance over a non-focused strategy in firms experiencing service disruptions.

Design/methodology/approach

The authors test their hypotheses using panel data of the US domestic airline industry from 1998 to 2019.

Findings

Overall, the study findings show that a focused strategy provides superior financial performance over a non-focused strategy in both stable environments and unpredictable environments. The authors also find that the effect of service disruptions on profitability is less pronounced for firms following a focused strategy. This shows that focused firms need to grow over time to sustain profitability. Their post hoc analysis shows that for a non-focused strategy (but not for a focused strategy), firm size moderates the effect of service disruptions on profitability. This suggests that a firm pursuing a non-focused strategy can mitigate the negative effect of service disruptions by increasing its size.

Originality/value

This is the first study that examines the effectiveness of the focused strategy in mitigating service disruptions. The results provide further support for the effectiveness of the focused strategy in responding to service disruptions in service organizations.

Abstract

Purpose

This paper aims to examine the relationship of supply chain disruption risk drivers to supply chain performance and firm performance outcomes.

Design/methodology/approach

Four disruption risk drivers for a supply chain are identified, namely, demand disruption risk, supply disruption risk, process disruption risk and environment disruption risk. A cross-sectional survey was developed and data was collected from 315 Chinese firms to determine the relationship of supply chain disruption risks to supply chain performance and firm performance.

Findings

The empirical findings show that supply disruption risks and process disruption risks have a significant impact on supply chain performance. In addition, this paper shows that supply disruptions, demand disruptions and process disruptions are significantly related to firm performance. This paper shows that supply chain disruption risks have different effects on supply chain performance and firm performance. Managers should be aware that disruption risk drivers can have an impact on firm performance that is different from their impact on supply chain performance. An important finding of the study is that the magnitude of the impact of disruption risks on supply chain performance is greater on the upstream side of the supply chain than on the downstream side of the supply chain.

Originality/value

This is one of the early studies to examine the effect of supply chain disruption risk drivers on both firm performance and supply chain performance. An important finding of the study is that the magnitude of the impact of disruption risks on supply chain performance is greater on the upstream side of the supply chain than on the downstream side of the supply chain.

Abstract

Purpose

The main components of resiliency, including resilience capacities, resilience activities and resilience measures, are identified, extracted and redefined by designing their ontologies. The integrated model is developed by adapting the PDCA (plan, do, check and act) model to resilience management and implementing the developed concepts in the model.

Design/methodology/approach

This study uses systems theory to define the main concepts discussed in the literature on resilience. This study then uses systems engineering theory and a resource-based view of the firm to develop an integrated framework to demonstrate how a resilient firm operates.

Findings

The revised terminologies and the integrated model address the current theoretical issues in the literature, and they also provide a reference model for practical implementation of resilience management at the firm level. Also, the integrated model addresses the role of innovation in resilience management.

Originality/value

The study examines the concept of resilience form a quality perspective and also examines how resilience and innovation are related.

Abstract

Purpose

This systematic literature review analyzes the academic literature to understand SC risk and resilience across different organizational sizes and industries. The academic literature has well discussed the causes of supply chain (SC) risk events, the impact of SC disruptions, and associated plans for SC resilience. However, the literature remains fragmented on the role of two fundamental elements in achieving SC resilience: the firm's size and the firm's industry as firms' contingent factors. Therefore, it is important to investigate and highlight SC resilience differences by size and industry type to establish more resilient firms.

Design/methodology/approach

Building upon the contingent resource-based view of the firm, the authors posit that organizational factors such as size and industry sector have important roles in developing organizational resilience capabilities. This systematic literature review and analysis is based on the structural and systematic analysis of high-ranked peer-reviewed journal papers from January 2000 to June 2021 collected through three global scientific databases (i.e. ProQuest, ScienceDirect, and Google Scholar) using relevant keywords.

Findings

This systematic literature review of 230 high-quality articles shows that SC risk events can be categorized into demand, supply, organizational, operational, environmental, and network/control risk events. This study suggests that the SC resilience plans developed by startups, small and mdium-sized enterprises (SMEs), and large organizations are not necessarily the same as those of large enterprises. While collaboration and networking and risk management are the most crucial resilience capabilities for all firms, applying lean and quality management principles and utilizing information technology are more crucial for SMEs. For large firms, knowledge management and contingency planning are more important.

Originality/value

This study provides a comprehensive review of the literature on SC resilience plans across different organizational sizes and industries, offering new insights into the nature and dynamics of startups', SMEs', and large enterprises' SC resilience in different industries. The study highlights the need for further investigation of SC risk and resilience for startups, SMEs, and different industries on a more detailed level using empirical data. This study’s findings have important implications for researchers and practitioners and guide the development of effective SC resilience strategies for different types of firms.

Abstract

Purpose

This study aims to investigate the effects of individual entrepreneurial orientation (IEO), entrepreneurial self-efficacy (ESE) and entrepreneurial managerial skills (EMS) on project performance at both the individual and team levels using a holistic framework.

Design/methodology/approach

Data were collected from 308 university students involved in two different types of projects (entrepreneurship and nonentrepreneurship) in Qatar.

Findings

The confirmatory factor analysis and structural equation modeling showed that both IEO and EMS positively and almost equally influenced project performance. However, ESE’s impact on project performance was significantly mediated by both IEO and EMS and, in practice, it should be considered a motivational factor for increasing the impact of IEO and EMS on project performance.

Practical implications

Project managers should recognize the value of the management and leadership skills examined in this study and their implications for project outcomes.

Originality/value

This study provides novel insights into the role these factors play in effective project management, thus allowing organizations to make effective decisions to reinforce these factors and gain a competitive advantage.

Abstract

Purpose

This study aims to investigate the effect of productivity and quality on profitability in the US airline industry.

Design/methodology/approach

Airlines operations and performance data were used to determine the effect of productivity and quality on profitability. Correlation and multivariate regression analysis have been used for data analysis.

Findings

The results show that labor productivity is the most significant predictor of profitability. On‐time performance has no relationship with profitability. The findings suggest that labor productivity, gas price, average annual maintenance cost and employee salary are significant predictors of profitability. The relationship between labor productivity and employee salary with profitability is positive, while gas price and average annual maintenance cost have a negative relationship with profitability.

Research limitations/implications

The research could be more detailed by taking into account measures of airline safety. Additional measures for service quality could be considered.

Practical implications

Operational performance (labor productivity) is the main source of profitability in the US airline industry followed by customer satisfaction and service quality.

Originality/value

The study captures the performance of the airline industry based on longitudinal data from 1989 to 2008. Previous studies have used either quarterly or monthly observations. Second, the study examines the significance of productivity and quality on profitability. Previous studies have provided little insight regarding the effect of productivity and quality on profitability.

Abstract

Purpose

The purpose of this paper is to develop a theoretical base for buyer-supplier quality outcomes (in the context of a strategic partnership) from the institutional theory of the firm. It examines quality outcomes within a partnership and demonstrates how the partners’ quality outcomes are related.

Design/methodology/approach

The paper examines quality outcomes within a strategic supply chain partnership (buyer-supplier) and demonstrates how the partners’ quality performance are related. Correlation analysis is used to examine the research hypothesis.

Findings

Utilizing the institutional theory and stakeholder theory of the firm, it is argued that within a strategic partnership, the quality outcomes of the partners are significantly related. By focusing on a strategic alliance within a strategic group in the US airline industry, it is shown that there is a significant relationship among quality outcomes of the partners within the strategic alliance.

Research limitations/implications

The analysis was limited to only one strategic partnership. Future research should examine quality outcomes among multiple strategic partnerships in order to validate the findings of this study.

Originality/value

The study discusses the importance of strategic alliances and networks of firms as determinants of firm quality performance.
