Abstract

Purpose

Supply chains must rebuild for resilience to respond to challenges posed by systemwide disruptions. Unlike past disruptions that were narrow in impact and short-term in duration, the Covid pandemic presented a systemic disruption and revealed shortcomings in responses. This study outlines an approach to rebuilding supply chains for resilience, integrating innovation in areas critical to supply chain management.

Design/methodology/approach

The study is based on extensive debates among the authors and their peers. The authors focus on three areas deemed fundamental to supply chain resilience: (1) forecasting, the starting point of supply chain planning, (2) the practices of supply chain risk management and (3) product design, the starting point of supply chain design. The authors’ debated and pooled their viewpoints to outline key changes to these areas in response to systemwide disruptions, supported by a narrative literature review of the evolving research, to identify research opportunities.

Findings

All three areas have evolved in response to the changed perspective on supply chain risk instigated by the pandemic and resulting in systemwide disruptions. Forecasting, or prediction generally, is evolving from statistical and time-series methods to human-augmented forecasting supplemented with visual analytics. Risk management has transitioned from enterprise to supply chain risk management to tackling systemic risk. Finally, product design principles have evolved from design-for-manufacturability to design-for-adaptability. All three approaches must work together.

Originality/value

The authors outline the evolution in research directions for forecasting, risk management and product design and present innovative research opportunities for building supply chain resilience against systemwide disruptions.

Abstract

Purpose

The purpose of this paper is to investigate the effects of personality dimensions (conscientiousness, neuroticism, extraversion, agreeableness, openness to experience, locus of control) on the efficacy of judgmental adjustments of statistical forecasts.

Design/methodology/approach

This paper uses a two-level hierarchical linear model to analyze a large data set obtained from an organizational setting (a quick service restaurant chain) that includes 3,812 judgmental adjustments of sales forecasts made by 112 store managers.

Findings

The results indicate that the average forecast accuracy improves as a result of judgmental adjustments, but performance of individual forecasters varies considerably based on their personality. Specifically, the trait of openness to experience tends to improve forecast accuracy while extraversion and external locus of control have negative effects.

Originality/value

Integration of human judgment with analytics algorithms is a major challenge for organizations. Documenting the impact of these traits on forecast accuracy opens the door for forecasting support system design, training, personnel selection and correction strategies that can be applied to judgmental adjustments.

Abstract

Purpose

The present manuscript assesses how firms should manage frequent supply chain disruption triggers and whether these firms should use existing supply chain competencies, develop new ones or both to mitigate any adverse consequences on financial performance.

Design/methodology/approach

Data for the study come from a survey administered to professionals in India. India was an appropriate base for the study because of its developing economy and businesses often facing SC disruptions in the marketplace.

Findings

The findings show that the negative association between the frequency of supply chain disruption triggers and financial performance is weaker when a firm utilizes supply chain exploitation competencies. Conversely, the negative association between the frequency of supply chain disruption triggers and financial performance becomes stronger when using supply chain exploration competencies. Most significantly, however, the authors show that a strategy of supply chain ambidexterity – one that combines both exploitation and exploration practices – is more beneficial in mitigating the impact of frequent disruption triggers on firm financial performance compared to the other strategies.

Originality/value

These findings contribute to the literature, extending the benefits of ambidexterity beyond domains of innovation, manufacturing flexibility, competitiveness and firm performance to include mitigation of supply chain disruptions.

Abstract

Accurate forecasting is one of the most critical issues for business planning. Knowing how best to generate forecasts and how others are performing this function is important information for managers. This study reports on forecasting practices in US firms based on a survey of 500 companies. In addition to information on techniques and software used, this survey attempts to gain insights into managerial forecasting practices. These include identifying common causes of forecast errors, typical problem areas, and plans for the future to improve forecasting. Based on these findings specific implications for managers are developed.

Abstract

The conditions under which forecasts from expert judgement outperform traditional quantitative methods are investigated. It is shown that judgement is better than quantitative techniques at estimating the magnitude, onset, and duration of temporary change. On the other hand, quantitative methods provide superior performance during periods of no change, or constancy, in the data pattern. These propositions were tested on a sample of real business time series. To demonstrate how these propositions might be implemented, and to assess the potential value of doing so, a simple rule is tested on when to switch from quantitative to judgemental forecasts. The results show that it significantly reduces forecast error. These findings provide operations managers with some guidelines as to when (and when not) they should intervene in the forecasting process.

Abstract

Accurate forecasting has become a challenge for companies operating in today's business environment, characterized by high uncertainty and short response times. Rapid technological innovations and e‐commerce have created an environment where historical data are often of limited value in predicting the future. In business organizations, the marketing function typically generates sales forecasts based on judgmental methods that rely heavily on subjective assessments and “soft” information, while operations rely more on quantitative data. Forecast generation rarely involves the pooling of information from these two functions. Increasingly, successful forecasting warrants the use of composite methodologies that incorporate a range of information from traditional quantitative computations usually used by operations, to marketing's judgmental assessments of markets. The purpose of this paper is to develop a framework for the integration of marketing's judgmental forecasts with traditional quantitative forecasting methods. Four integration methodologies are presented and evaluated relative to their appropriateness in combining forecasts within an organizational context. Our assessment considers human factors such as ownership, and the location of final forecast generation within the organization. Although each methodology has its strengths and weaknesses, not every methodology is appropriate for every organizational context.

Abstract

Purpose

The purpose of this paper is to explore the impact of buyer investment in interorganizational, information‐related connectivity enablers on supplier firm performance within the context of buyer‐seller matched dyads.

Design/methodology/approach

Data for this study were obtained from a field survey. A mail questionnaire was constructed that contained items measuring the five key constructs of interest. Based on the supply chain information literature and the relational view, two competing models linking the focal constructs using structural equation modeling were evaluated.

Findings

The results of the study indicate that buyer‐to‐supplier information sharing, buyer‐to‐supplier performance feedback, and buyer investment in inter‐organizational information technology are key enablers of buyer‐to‐supplier communication openness. However, only buyer‐to‐supplier communication openness plays the direct and critical role in achieving significant performance improvement.

Research limitations/implications

In this study performance is only examined from the supplier's perspective. It would be valuable to reevaluate and compare the performance outcomes from a buyer's perspective as well, or even more significantly, to compare these findings in a dyadic study where paired buyer and supplier data are collected over time to establish a pattern governing these efforts.

Practical implications

The fact that investments in the buyer‐side information resources engender supplier‐side competitiveness provides an incentive for suppliers to assist buyers in their investments in buyer‐side information resources. The study provides validation for the positive impact of such investments on supplier performance, therefore reassuring suppliers that their contribution to the dyad will pay off.

Originality/value

While information connectivity between buyers and suppliers has long been considered a critical enabler of buyer‐supplier integration, research had yet to explore the relationship between buyer investments in interorganizational information initiatives and supplier performance. The paper has addressed this gap.

Abstract

Purpose

This article aims to uncover the influence employment relations, and more specifically union avoidance has on the decision to outsource road transport. Employment Relations literature often attributes outsourcing decision to decollectivist strategies, minimising the influence unions have in their workplaces or to labour cost reduction objectives. These explanations, however, fail to explain why some firms do not outsource when their sourcing structure incurs greater union involvement or industrial relation.

Design/methodology/approach

The author examines two case studies. Company A and Company B, while operating in a similar environment, selling similar products and offering a similar home delivery service have adopted different governance structures for their outbound transport function; Company A has integrated while Company B has outsourced. Was union avoidance or transaction cost reductions central to their respective decisions?

Findings

Company A did not integrate in an effort to circumvent union intervention or reduce costs. Company A’s integration, on the contrary, increased the firm’s dealings with unions, as well as regulatory compliance and transaction costs. Company B’s decision to outsource yielded similar results. While not experiencing an increase in union intervention, the firm failed to reduce the density of unionised labour and by maintaining ownership of delivery vehicles, saw a rise in costs.

Originality/value

Union avoidance is not an explanatory factor in the sourcing decision, nor is it possible to explain through transaction cost economics. Explication for outcomes lies in value enhancement. Companies are willing to incur higher employment relations and transport costs if the result is higher value capture.

Abstract

Purpose

This study aims to examine publications of supply chain management (SCM) researchers from across the world and maps the leadership role of authors and institutions based on how prolific they are in publishing and on network measures of centrality while accounting for the quality of the outlets that they publish in. It aims to inform stakeholders on who the leading SCM scholars are, their primary areas of SCM research, their publication profiles and the nature of their networks. It also identifies and informs on the leading SCM research institutions of the world and where leadership in specific areas of SCM research is emerging from.

Design/methodology/approach

Based on SCM papers appearing in a set of seven leading journals over the 15-year period of 2001-2015, publication scores and social network analysis measures of total degree centrality and Bonacich power centrality are used to identify the highest ranked agents in SCM research overall, as well as in some specific areas of SCM research. Social network analysis is also used to examine the nature and scope of the networks of the ranked agents and where leadership in SCM research is emerging from.

Findings

Authors and institutions from the USA and UK are found to dominate much of the rankings in SCM research both by publication score and social network analysis measures of centrality. In examining the networks of the very top authors and institutions of the world, their networks are found to be more inward-looking (country-centric) than outward-looking (globally dispersed). Further, researchers in Europe and Asia alike are found to exhibit significant continental inclinations in their network formations with researchers in Europe displaying greater propensity to collaborate with their European-based counterparts and researchers in Asia with their Asian-based counterparts. Also, from among the journals, Supply Chain Management: An International Journal is found to exhibit a far more expansive global reach than any of the other journals.

Research limitations/implications

The journal set used in this study, though representative of high-quality SCM research outlets, is not exhaustive of all potential outlets that publish SCM research. Further, the measure of quality that this study assigns to the various publications is based solely on a publication score that accounts for the quality of the journals, as rated by Association of Business Schools that the papers appear in and nothing else.

Practical implications

By informing the community of stakeholders of SCM research about the top-ranked SCM authors, institutions and countries of the world, the nature of their networks, as well as what the primary areas of SCM research of the leading authors in the world are, this research provides stakeholders, including managers, researchers and students, information that is helpful to them not only because of the insights it provides but also for the gauging of potential for embedding themselves in specific networks, engaging in collaborative research with the leading agents or pursuing educational opportunities with them.

Originality/value

This research is the first of its kind to identify and rank the top SCM authors and institutions from across the world using a representative set of seven leading SCM and primary OM journals based on publication scores and social network measures of centrality. The research is also the first of its kind to identify and rank the top authors and institutions within specific areas of SCM research and to identify future research opportunities relating to aspects of collaboration and networking in research endeavors.
