Abstract

Purpose

The purpose of this paper is to investigate the effectiveness of supply chain integration in different contexts. More specifically, it aims to show that supply chain integration is only effective in buyer‐supplier relationships characterised by high supply complexity.

Design/methodology/approach

A survey‐based research design is developed to measure different dimensions or aspects of supply chain integration and supply complexity. Data were collected among manufacturers in The Netherlands and Spain.

Findings

This research shows that supply chain integration increases performance if supply complexity is high, while a very limited or no influence of supply chain integration can be detected in case of low supply complexity. The results also show that in high supply complexity environments the use of structured communication means to achieve supply chain integration has a negative effect on cost performance.

Research limitations/implications

The limited sample size prohibits estimating and testing of more comprehensive models of the relationship between supply chain integration and performance. Specifically, the authors were not able to further investigate how different supply chain integration dimensions are inter‐related and mutually reinforce one another to improve performance.

Practical implications

The main managerial lesson is that, in contrast to what has been written in many books and other popular publications, high levels of supply chain integration are only necessary in environments characterised by high supply complexity.

Originality/value

This study helps to better understand context in supply chain management research. Specifically, it investigates the moderating effect of supply complexity on the integration‐performance relationship, a topic suggested by Bozarth et al. as a line for further research.

Abstract

Purpose

Emergency care delivery is a process requiring input from various healthcare professionals within the hospital. To deliver efficient and effective emergency care, professionals must integrate rapidly at multiple interfaces, working across functional, spatial and professional boundaries. Yet, the interdisciplinary nature of emergency care presents a challenge to the optimization of patient flow, as specialization and functional differentiation restrict integration efforts. This study aims to question what boundaries exist at the level of professionals and explores how these boundaries may come to influence integration and operational performance.

Design/methodology/approach

To provide a more holistic understanding of the inherent challenges to integration at the level of professionals and in contexts where professionals play a key role in determining operational performance, the authors carried out an in-depth case study at a busy, Level 1 trauma center in The Netherlands. In total, 28 interviews were conducted over an 18-month period.

Findings

The authors reveal the existence of structural, relational and cultural barriers between (medical) professionals from different disciplines. The study findings demonstrate how relational and cultural boundaries between professionals interrupt flows and delay service processes.

Originality/value

This study highlights the importance of interpersonal and cultural dynamics for internal integration and operational performance in emergency care processes. The authors unveil how the presence of professional boundaries creates opportunity for conflict and delays at important interfaces within the emergency care process, and can ultimately accumulate, disrupting patient flow and increasing lead times.

Abstract

Purpose

The purpose of this paper is to investigate the impact of different dimensions of supply chain integration on performance, while considering both the interconnections between these supply chain integration dimensions and the effect of context. Specifically, the authors investigate the relationship between two enablers (communication infrastructure and cooperative behaviour) and two practices (planning information and joint improvement), and the moderating effect of supply complexity on their relationship with performance.

Design/methodology/approach

A survey among 145 Dutch and Spanish manufacturers is used to gather data on the buyer‐supplier relationship. Both the sample and two subsamples – for high and low supply complexity – are analysed using SmartPLS.

Findings

The paper finds that two dimensions – communication infrastructure and cooperative behaviour – enable the two collaborative practices: joint improvement and planning information. All mentioned supply chain integration dimensions, except joint improvement are related to performance, but specifically if the supply complexity is high. Among these dimensions the effect of cooperative behaviour is relatively high.

Originality/value

This paper adds to our understanding of how contingencies influence the supply chain. It is the first paper that investigates the moderating effect of the complexity of the process of delivery (supply complexity) on the effectiveness of supply chain integration practices.

Abstract

Purpose

The concept of buyer focus has recently been introduced as a new supply chain strategy, although the design and operation of buyer‐focused cells have hardly been investigated. The purpose of this paper is to investigate how buyer‐focused cells realise responsiveness.

Design/methodology/approach

The paper explores the origins of buyer focus by synthesising the literature on focus and supply chain management (SCM). The recent model of responsiveness by Holweg is used to analyse two cases in the semi‐conductor industry. Based on the literature and the case‐findings the model is further developed.

Findings

The main findings of the paper are that: the model of responsiveness can be used to better understand buyer‐focused cells as a supply chain strategy, but needs to be enhanced with additional elements; two of the dimensions of Holweg's model (product and volume) seem to determine the third (process) dimension; designing and operating buyer‐focused cells is a blend of well‐chosen and proven solutions combined with close integration with the buyer.

Research limitations/implications

The extended model and the operation of buyer‐focused cells need further refinement and research using the key factors so far established.

Practical implications

The paper explores both the contingency factors and the major design and operating factors related to a new supply chain strategy (buyer‐focused cells) which is aimed at increasing responsiveness, and investigates two practical cases. Managers can use the developed framework to better understand their own situation and guide decision making.

Originality/value

The paper aims at further developing and understanding the responsiveness of buyer‐focused cells by drawing on previous contributions in the literature on SCM and the focused factory. Through this, the authors add to the theory of responsiveness and to empirical knowledge on the design and operation of buyer‐focused cells.

Abstract

Purpose

Technology uncertainty poses significant challenges to manufacturers, as rapid changes in product and/or process standards and specifications can disrupt the smooth flow of materials in extended supply chains. Practitioners and researchers alike who take a relational perspective widely regard supplier involvement as a potentially effective strategy to cope with technology uncertainty, as focal manufacturers can tap into their upstream supply networks for complementary resources and capabilities. However, the literature lacks a nuanced understanding of the supplier involvement processes. Specifically, the role of resource dependence for supplier involvement has yet to be systematically understood. To fill this gap, this study aims to combine the relational perspective with the resource-dependence perspective to explore how buyer dependence, supplier dependence and buyer–supplier interdependence influence buyers’ decision-making on tapping into upstream supply networks for coping with technology uncertainty.

Design/methodology/approach

To test the hypotheses, a survey is conducted among Dutch firms with more than 50 employees in the discrete manufacturing industries (ISIC 28-35), resulting in a sample of 125 manufacturers.

Findings

First, there is a significantly positive relationship between technology uncertainty and supplier involvement, giving support to the expectation that buyers are indeed involving their key suppliers in the product/process design and improvement, as a response to technology uncertainty. Second, buyer dependence and interdependence are found to be positively moderating the relationship between technology uncertainty and supplier involvement. In contrast, supplier dependence has a negative moderating effect on the baseline relationship.

Research limitations/implications

The authors contribute to a relational view on buyer–supplier relationships by showing that the validity of this view, in the context of technology uncertainty, is contingent on the resource dependence between buyers and suppliers, and the authors contribute to the supply chain management literature more generally by combining a relational perspective with a resource-dependence perspective.

Practical implications

The findings provide several nuanced insights into the effect of resource dependence (buyer dependence, supplier dependence and interdependence) on supplier involvement for coping with technology uncertainty.

Originality/value

This study contributes to the supply chain management research by going beyond the benefits of supplier involvement and highlights the circumstances under which supplier involvement is likely to occur.

Abstract

Purpose

The purpose of this paper is to review and classify survey‐based research connecting information and communication technology (ICT), supply chain management (SCM), and supply chain (SC) performance. The review evaluates present empirical results and aims at detecting explanations for similarities and differences in reported findings in the current literature.

Design/methodology/approach

The paper is based upon a structured literature review of the major journals in the fields of operations management, logistics, and information systems.

Findings

The point of departure in this paper is the possible inconsistency in reported findings within this field of research. The paper finds that measurements and constructs in all three major variables (ICT, SCM, SC performance) are different and often incomparable, and contextual factors are not systematically considered. Surprisingly, despite these differences, the papers reviewed show that generally, there is a positive direct or indirect effect of ICT on performance and SCM.

Research limitations/implications

The paper aims at reviewing the survey‐based literature only. Findings from case studies and other types of studies are not considered. An implication of this paper might be to reconsider how future survey studies should be designed and what constructs and issues need to be incorporated. Specifically, the relationships between single technologies, aspects of SCM and performance dimensions need specific attention in future research.

Originality/value

The paper offers a systematic review that helps to further develop our understanding of the relationship of SCM, ICT, and SC performance.

Abstract

Purpose

Buyer‐focused operations aim at a high level of supply chain alignment by singling out resources for one buyer in order to serve this buyer optimally. The purpose of this paper is to identify what business characteristics make suppliers choose buyer‐focused operations as a supply chain strategy in their relationships with key buyers.

Design/methodology/approach

A broad range of qualitative and quantitative data was collected during interviews and plant visits in a multi‐case study research design. Nine units and 42 supply links with key buyers were investigated and analysed.

Findings

The suppliers choose buyer‐focused operations for different reasons. As expected, some of them choose buyer‐focused operations to fulfil the buyer's requirements in terms of flexibility (mix, volume, specification and timing). However, in other situations, buyer‐focus is used for other reasons: mostly to perform additional assembly operations. Suppliers rarely consider buyer‐focus of core production technology in relationships with buyers for which cost and speed are the main order‐winners.

Research limitations/implications

The study is based on a relatively small number of cases. Although the findings confirm the theoretical framework, more empirical work is needed to better understand different forms of buyer‐focus. Further research should also point out if and how mutual trust and risk dispersal influence decisions to invest in buyer‐focused resources.

Practical implications

The results of this paper help managers in choosing between different forms of buyer‐focus, based on the specific characteristics of a supply chain link.

Originality/value

The paper introduces focus into the domain of supply chain management and shows that striving for close cooperation in a supply relationship needs to be carefully considered and depends on the business characteristics. The paper contributes also to a better understanding of the concept of buyer‐focus and distinguishes different types.

Abstract

Purpose

Hospitals struggle to integrate the planning from different departments; resulting in unacceptable waiting times for patients. The literature mainly addresses general, organizational factors inhibiting or enabling integration and omits important factors stemming from the care delivery process. Therefore, the purpose of this paper is to uncover operational antecedents and to assess their effect on the integration of hospital planning.

Design/methodology/approach

The study is based on a three-hospital multi-case study. The main findings stem from over 40 in-depth interviews with specialists, nurses, planners, and managers of four specialties that are all involved in the orthopedic internal supply chain.

Findings

This study identifies five critical operational antecedents: performance management, shared resources, information technology, process visibility, and uncertainty/variability. The latter two are of specific importance in a healthcare context. Three distinctive roles are identified; initiating (performance management and process visibility), facilitating (information technology), and inhibiting (shared resources and uncertainty/variability).

Practical implications

The authors address how integration can be achieved, rather than merely prescribing integration as a means to improve performance. The identification of specific operational antecedents and their role help managers to find tangible ways to effectively integrate hospital planning which increases hospital performance.

Originality/value

First, the identified operational antecedents are essential supplementary factors to more common organizational and behavioral antecedents. Second, in contrast to earlier contributions the authors show the effects of antecedents on three different stages of integration, rather than on integration in general.

Abstract

Purpose

The aim of this paper is to investigate which integrative planning and control practices are used in hospitals and what their effects are on patient flow.

Design/methodology/approach

The study is based on a three‐hospital multi‐case study carried out in The Netherlands. The main findings are based on over 40 in‐depth interviews and the analysis of detailed patient flow data. The analysis of the flow data is used to explore the effects of integrative practices on lead times and patient flow.

Findings

Based on the various patient groups examined in the different hospitals, four integrative practices stand out: sharing waiting list information, sharing planning information, cross‐departmental planning, and combining appointments. In line with earlier studies, the overall level of integration in hospitals was found to be low. However, patient flow performance is significantly better in those hospitals that employ more of the above‐mentioned integrative practices.

Research limitations/implications

The study was limited to three major patient groups within the orthopedic supply chain. The deliberate choice for these patients groups was based on the expectations that integration in hospitals is relatively low and that the highest levels of integration would be found in high volume – low variety patient groups. Further research should include patient groups with less favorable characteristics such as lower volumes and/or greater variety.

Practical implications

This study provides clear support for the value of integration initiatives in healthcare operations. The performance of hospitals, in terms of patient flows, benefits from cooperation between the various members of an internal supply chain. Hospital administrators and medical professionals could learn from these results and attempt to abandon their silo mentality and start integrating for and their patients' and their own benefit.

Originality/value

Despite the importance of integration in hospitals, little is known about the integrative practices hospitals actually employ. Most existing studies on patient flows are confined to a single stage in the care process. In this study, the effects of integration in the internal supply chain from the first visit to the end of treatment are examined.
