This paper aims to investigate the bridging role of first-tier suppliers in diffusing sustainability in supply networks and how this role is facilitated by the procurement function.

The paper is based on an embedded case study of two supply networks of a coffee beans roasting company. The embedded cases focus on coffee beans and packaging supply networks.

The findings reveal less than expected involvement of the focal company and its procurement function in sustainability implementation with first-tier suppliers. Instead, sustainability diffuses upstream to lower-tier suppliers but also downstream, against the tide, as a result of the various bridging roles performed by first-tier suppliers.

This paper provides two theoretical contributions. First, it contributes to the sustainable supply network management literature by providing rich insights on sustainability diffusion to lower-tier suppliers and the role of first-tier suppliers in this process. Second, the paper contributes to structural hole theory by revealing a typology of bridging roles that actors, such as suppliers, undertake in the sustainability context.

The paper provides managers with practical insights on how sustainability can be diffused in the supply network and the different roles that first-tier suppliers can play in this direction.

This paper shows that sustainability diffusion to lower-tier suppliers is possible in the absence of focal company procurement involvement when bridging roles are undertaken by first-tier suppliers and their procurement functions are involved in the implementation process. These bridging roles facilitate sustainability diffusion both upstream and downstream.

This paper explores the development of modular supply within the automotive sector with particular emphasis on the impact that modularization is likely to have on the value‐adding processes of key component suppliers. In addition, a reclassification of the term “first‐tier” supplier is proposed with a view to exploring the attributes necessary for such suppliers to succeed within the emerging modular environment.

The present study considers disruption in the buyer–supplier–supplier triad. This triad has a common second-tier supplier as the disruption source, which gives us the tetradic context. The goal is to advance the knowledge on how a first-tier supplier's resilience against lower-tier disruptive events can be developed through horizontally connecting with the other first-tier supplier and how the buyer can benefit from its first-tier suppliers' resilience capability.

Data from 33 triads was collected and analyzed.

As predicted, coopetition between two first-tier suppliers increases the first-tier supplier's capability to be resilient to disruptive events emanating from a lower tier source. However, contrary to initial theorization, the first-tier supplier's resilience capability affects the buyer's performance during disruptive events negatively. With increasing buyer–supplier social bonds, this negative relationship can partly be alleviated.

Analyzing resilience within a triad to a disruption in the tetradic context reveals unexpected dynamics. Individual supplier's resilience may have a negative impact on the buyer's resilience in certain disruption events.

The buyer can increase collective suppliers' resilience through establishing horizontal links. To prevent becoming a victim of the supplier's resilience in the event of a second-tier disruption, a buyer needs to become a member of the supplier's relational network.

We propose that resilience can rest with the suppliers. This observation has implications for the buyer when selecting and coordinating suppliers. Further, it considers a context beyond a triad by venturing into the tetradic context. We anticipate more studies in tetrads in future and this study can serve as a bridge.

This paper contends that the description of tiering within automotive supply chains is likely to require redefining in light of the development of modular supply and that a natural consequence of modular supply will be the transfer of value‐adding activity throughout the supply chain. Two concepts are presented to illustrate the characteristics that are likely to be required for suppliers to succeed within a modular environment. These concepts are applied to a supply chain currently in the process of accommodating modular supply. The findings suggest that whilst modularity accrues a number of tangible benefits to both the original equipment manufacturer (OEM) buyer and the modular supplier, the skills required to become a modular supplier are likely to result in a number of first‐tier suppliers either exiting the industry or becoming second or third‐tier suppliers.

This paper aims to empirically explore demand-related information sharing in the extended supply chain.

Through a single, embedded case design, a range of methods are used to collect data from companies representing three different supply chain tiers, including focal company, first-tier suppliers and first-tier customers. The collected data are analysed through the theoretical lens of interdependence.

The findings indicate that the supply chain actors adapt information sharing to the pooled, serial or reciprocal type of interdependence. Information sharing is thus increased with key dyadic partners representing, for example, unique offerings and high market shares as percentage of total expenditure/sales. The study also unearths several barriers to information sharing beyond dyadic ties, including problems related to dis-aggregated, misinterpreted and/or incomplete information.

The study empirically contributes to the existing literature by exploring information sharing in the extended supply chain and by suggesting different approaches to information sharing depending on the type and intensity of interdependence between supply chain partners. Further, the paper contributes to the existing literature on barriers of information sharing in supply chains by identifying barriers specific to multi-tier information sharing. “Meta-information” (i.e. information about the shared information) is needed to overcome some of the barriers of sharing information in cases of weak, pooled interdependencies in the supply chain.

Similar to previous empirical research, this exploratory study indicates that companies, in general, refrain from sharing information beyond dyadic ties. Supply chain managers would instead mostly focus on stronger, reciprocal interdependencies and emphasise dyadic information sharing. To further guide managers, a demand profiling framework considering market share and demand uncertainty is presented. It may be interesting to engage in multi-tier information sharing in particular cases where strong interdependence exists between three or more partners.

This study contributes to existing research on information sharing in supply chains by empirically studying information sharing in an extended supply chain, applying interdependence theory as its analytical framework and unearthing several barriers that are specific to multi-tier information sharing.

The goal is to manage the key value‐added processes from the “suppliers' supplier to the customers' customer.” Such end‐to‐end supply chain integration is very rare; however, many companies actively strive to implement initiatives in the areas of new product development, cycle time reduction, process redesign, cost minimization, and quality improvement across organizational boundaries. Most efforts are dyadic, focusing on a buyer/supplier relationship. Few examples of multi‐tier implementation efforts have been documented. This paper looks at the challenges encountered in the implementation of a quality initiative in the semiconductor industry. The focus is on the challenges encountered as a successful first‐tier implementation was driven back to the second tier. Initial efforts failed and responsibility for second‐tier implementation was passed back to the first‐tier suppliers. Efforts at this level continued to stall because the leverage dynamics of the supply chain was very different as smaller, second‐tier suppliers were engaged and encouraged to adopt the new quality standard.

With the increasing competition among the industries, they remain under pressure as how to select the best set of suppliers for the competitive edge. Often, it has been challenging to develop an effective set of suppliers due to varied and asymmetric mode of criteria. The purpose of this paper is to develop a responsive chain under original equipment manufacturer (OEM).

This study proposes a responsive chain under a two-echelon system (TES) of OEM, which needs to collaborate with a set of suppliers at each echelon through an integrated methodology of AHP and TOPSIS. According to the OEM’s criteria, demands and suppliers’ capacity vary with time, therefore they are not static for a longer period. Hence, supplier selection (SS) problem possesses dynamicity in real practice. For this, MILP is used for finding optimal order quantities based on the optimal ranking at each echelon in the multi-period scenario. Subsequently, sensitivity analysis (SA) is conducted through Taguchi method of parameter design (TMPD) to achieve an optimal ranking in the TES.

This study suggests optimal criteria’s weight, percentage contribution, and flexibility for the suppliers and manufacturers involving through maximum demand strategy at each echelon of OEM. It also provides robust group of suppliers and manufacturers in the TES through optimal ranking and simultaneously in the order allocations. Furthermore, it restricts the number of suppliers and manufactures at each echelon through proposed methodology to obtain the solution in a very short running time.

To validate this model, a real data set for the case of chain conveyor company is used. This adopted methodology can suggest the organization that how the approach should be implemented.

This paper aims to examine how lack of financial cooperation damages the operational efficiency of supply chains. The thesis is that economic and technological forces are provoking increasing financial tensions that push companies to transfer their credit needs and inventory requirements to their weakest suppliers. Thus, what might initially seem positive from an individual perspective can in fact generate losses in production efficiency for the supply chain as a whole.

This paper uses official data collected from 116 first- and second-tier suppliers in the Spanish automotive components sector, covering nine years (2001-2009). The relationships between the key variables are analysed using panel data estimations.

Significant differences were found between the working capital (WC) of first- and second-tier companies, proving additionally that although this approach may temporarily improve the results of first-tier suppliers, it leads to lower production efficiency in plants throughout the value chain.

Practitioners should avoid short-sighted attitudes when organizing the supply chain on a cooperative basis, going beyond the conventional wisdom on physical and information flows between original equipment manufacturers and their suppliers to reach upstream stages and embracing financial considerations.

The paper takes a novel approach to the issue of inter-organizational collaboration in the supply chain, aiming to go beyond conventional Lean Supply practices. From an empirical point of view, while much of the research on the topic utilizes key informant insights collected using psychometric data collection techniques, this study uses different financial proxies collected from secondary panel data.

Describes an empirical study examining the strategies of auto parts suppliers to transplanted Japanese OEMs. Finds that suppliers have become more customer‐focused, following the marketing concept, and also more aggressive in buying from second tier suppliers, in accordance with reverse marketing. Examines the background to the growth of Japanese OEMs in North America, together with an analysis of the traditional marketing concept, reverse marketing and the Japanese hierarchical structure of suppliers. Concludes that reverse marketing leads to strong partnerships, and that relationships with both existing and new suppliers must be developed. Relates the research to the oretical concepts and offers managerial recommendations.

The purpose of this paper is to apply self-determination theory (SDT) to green supply chain management (GSCM) and explore how green supplier selection (GSS) drives GSCM performance and how realisation of improved GSCM performance is contingent upon SDT mechanisms of autonomy, competence and relatedness.

This study draws on 18 semi-structured interviews and secondary data from a Germany-based first-tier aircraft interior manufacturer and its six key suppliers. The focal company was selected because it is recognised as having achieved high GSCM standards in the aerospace industry.

The study draws out the importance of GSS, distinguishing between new and legacy suppliers, and offers significant insights into how suppliers’ motivation and downstream GSCM criteria can be internalised in second-tier suppliers to drive GSCM performance.

GSS should be considered not only for new suppliers but also at an ongoing basis for legacy suppliers. Focal companies must realise the importance of motivating supply chain partners to realise GSCM practices and need to first build-up autonomy before focussing on competence and relatedness sub-dimensions.

The authors make a significant contribution to the GSCM literature by conducting a study of first-tier-second-tier relationships, thus moving beyond the buyer-supplier relationships investigated in extant studies. The results theoretically and empirically draw out key factors in GSS and supplier motivation in engaging with GSCM practices, thus driving GSCM performance.
