Structural model for analysis of key performance indicators for sustainable manufacturer–supplier collaboration: A grey-decision-making trial and evaluation laboratory-based approach

With growing competition in the market and dire need for sustainability, it has become imperative for companies to build long-term relationship with their supply chain partners through sustainable collaboration. Among these, the supplier–manufacturer relationship is crucial for improved organizational, business and sustainable performance. Sustainable collaboration with suppliers involves crucial decision-making processes such as continuous supplier monitoring and supplier development. Hence, a critical challenge that a company faces is to identify the key performance indicators (KPIs) for assessing the performance of a supplier for sustainable collaboration. In this regard, this study focuses on identification of KPIs for an Indian home appliance company through exhaustive discussions involving multiple decision-makers. Further, a grey-based decision-making trial and evaluation laboratory (DEMATEL) model is proposed in the study for analysing the importance levels among the fifteen KPIs based on multiple stakeholder perspectives. The results of the grey structural model indicate seven KPIs as influencing KPIs and eight KPIs as influenced KPIs. The KPI ‘Information disclosure’ has been identified as the most influential KPI for the evaluation of suppliers for sustainable collaboration. The implications drawn from the result analysis model can provide meaningful insights to managers for identifying strategies towards strengthening the supplier–manufacturer relationship and achieving organizational and market competence.     

Strategic purchasing and supplier partnerships—The role of a third party organization

This study explored how a credible third party facilitated the development of supplier partnerships. By identifying qualified potential suppliers, serving as a surrogate for legitimacy for supplier firms and providing a market place for the potential partners to meet, the third party organization provided key compensating mechanisms to reduce the power and social distance and overall transaction costs associated with collaborating to effect supplier relationships between the parties. The study contributes to the supply and purchasing literature by integrating the role of third parties into research on buyer–supplier relationships that have so far been viewed predominantly as dyads and by demonstrating how third parties may actually influence relationships between buyers and suppliers. Our findings also provide firms with some guidelines on building successful buyer–supplier partnerships.     

Effective Control Rights in Vertical R&D Collaboration

Because of increasing technological complexity of new products, the manufacturers of final products more often seek access to external sources of knowledge at the early, market‐distant stages of innovation processes. However, they are confronted with a specifically high danger of moral hazard. Traditional management instruments fail to control that danger mainly for two reasons. First, the supplier activities are not transparent. Second, market‐distant R&D results are credence goods whose quality cannot be evaluated, not even ex post. It is the theory of incomplete contracts that solves the problem by allocating the so‐called control rights to the supplier. These rights primarily regulate the assignment of the intellectual property rights, the control of the R&D process, and the marketing of the final products that are based on the delivered R&D results. To date, we do not have any empirical evidence about the relative effectiveness of these control rights. Moreover, studies on incomplete contracts in R&D alliances only focused on the collaboration between biotechnology and pharmaceutical firms. Our study fills these gaps. On the basis of a sample of French and German R&D suppliers, we find that only enforceable intellectual property rights assigned to the supplier effectively control moral hazard.

‘Sweet deals’: State-owned enterprises,corruption and repeated contracts in public procurement

We show how a price analysis of stable relations between customer and supplier in the public procurement of homogeneous goods can help differentiate opportunistic from honest behaviour among economic agents. We consider two types of stable relations: repeated procurements and connections based on the state ownership of suppliers. On the basis of a large dataset on the procurement of granulated sugar in Russia from 2011 to 2013, we find that for private suppliers, prices of repeated contracts were lower compared to one-time deals when procured through more transparent procedures and higher when procured through non-transparent procedures. For non-transparent procedures, we observe significant overpricing of contracts with state-owned suppliers compared to private suppliers, especially in the case of repeated contracts, whereas for competitive e-auctions, there is only a small difference between the contract prices of state-owned suppliers and private suppliers.     

Do dependent suppliers benefit from buying firms’ sustainability practices?

In view of the limited understanding and research on the effect of sustainable supplier development practices on supplier performance, this study examines the impact that the implementation of assessment and collaboration practices have on supplier performance outcomes. In addition, we investigate the role that supplier dependence has on the performance outcomes of assessment on and collaboration with suppliers. Based on a sample of 129 Chinese manufacturing firms, we run a series of OLS regressions to test our theoretical models. The findings suggest that collaboration improves supplier performance, while assessment causes a deterioration. In addition, supplier dependence could be leveraged for suppliers to gain performance improvements through collaborative practices.     

How does justice matter in achieving buyer–supplier relationship performance?

This study presents an analysis exploring how four types of justice (distributive, procedural, interpersonal, and informational) influence dyadic relationship performance in the buyer–supplier context. Underpinned by loose coupling theory, we build a mediating framework in which we propose that a high level of justice (or fairness) as mutually perceived by both parties drives buyer–supplier relationship performance through bolstered coupling links in mutual knowledge sharing, continuous commitment, and relationship investment. Our survey of 216 paired manufacturers (suppliers) and distributors (buyers) in China generally supports this argument, leading to a conclusion that justice is not a direct determinant of buyer–supplier performance but a critical conduit that nourishes mid-range coupling behaviors, which in turn promotes a successful relationship. Based on findings from this study, firms are encouraged to endorse all four kinds of justice in managing supply chain relationships. However, when constrained by resources, the recommendation for managers is to focus on achieving a high level of perceptual convergence on procedural justice and informational justice with the exchange partner, because mutual perceptions of procedural and informational justice have the strongest effects on coupling behaviors and buyer–supplier relationship performance.     

Governing local supplier opportunism in China: Moderating role of institutional forces

China provides a vast and prominent manufacturing base, so curtailing its local supplier opportunism represents a primary concern for local and foreign buyers. Drawing on institutional theory, this study examines how regulatory uncertainty and relationship structure moderate the role of contracts and trust in restricting local supplier opportunism in China. An analysis of 293 buyer–supplier dyads in China reveals that contracts are more effective in deterring supplier opportunism when regulatory uncertainty is high. In addition, contracts help curtail opportunism more in domestic, compared with international, buyer–supplier relationships, whereas trust is more effective in restricting supplier opportunism in international relationships than in domestic ones.     

Can supplier innovations substitute for internal R&D? A multiple case study from an absorptive capacity perspective

Prior literature suggests that significant internal R&D resources are needed to leverage suppliers for innovation and that external knowledge sources can be used to complement the internal knowledge base. Based on the analysis of four inbound open innovation projects at Fortum, a multinational energy utility company, we argue that companies with low R&D intensity may adopt an alternative approach which aims at substituting – not merely complementing – internal R&D with external innovations. We adopt the absorptive capacity perspective while investigating the cases and focus on four distinct capabilities: acquisition, assimilation, transformation, and exploitation. We find that the substitution approach consists of short-term research on new technological areas in order to gain the ability to identify and evaluate alternative technologies, as well as joint business models and operations based on complementary capabilities between the parties. The cases also suggest that the innovation process requires significant collaboration and the buying company's supplier management capabilities may improve the success of inbound open innovation projects of this type.     

Internal and external suppliers in manufacturing networks—An empirical analysis

The purpose of the paper is to explore the way manufacturing firms use internal and external suppliers in the design and management of manufacturing networks. The main area of interest is to explore the similarities and differences between internal and external suppliers, with respect to their roles and the reasons for choosing a certain type of supplier. We base our analysis on data from 104 Swedish manufacturing plants and their corresponding manufacturing networks of internal and external suppliers. The results of the study show that there are significant differences between the criteria that are influential in choosing a certain type of supplier. The choice of an internal supplier is largely based on a single corporate decision, while an external supplier has to perform well on a number of criteria (primarily quality, cost, and delivery dependability). When comparing the selection criteria with competitive priorities and plant performance, we find that the criteria for selecting external suppliers has a better match than those for selecting internal suppliers. The sample contained plants having only external suppliers as well as plants having both internal and external suppliers, but the selection criteria for external suppliers are the same for both groups and not dependent upon the presence or absence of internal suppliers.     

Supplier–supplier relationships in the buyer–supplier triad: Building theories from eight case studies

Many researchers have studied how the buying company manages its relationship with suppliers (i.e. buyer–supplier relationship). Extending this genre of study, researchers have recently shown interest in investigating how the buying company manages relationships between the suppliers (i.e. supplier–supplier relationship). In other words, just as the relationship with the suppliers does, the relationships between suppliers have strategic implications for the buyer. We present in this study eight cases that describe supplier–supplier relationship dynamics. Using theory building through case studies, we identify five archetypes of supplier–supplier relationships. Each type of relationship is a unique configuration of the relational characteristics. We also present working propositions that associate the antecedent conditions that lead to these archetypes and eventual performance implications.     

Supplier–supplier relationships in buyer–supplier–supplier triads: Implications for supplier performance

A growing number of studies and evidence from industries suggest that, besides managing the relationship with its suppliers, a buyer needs to proactively manage the relationships between those suppliers. In a buyer–supplier–supplier relationship triad, the buyer, as the contracting entity, influences the suppliers’ behaviors and the relationship between them. By considering the relationships in such a triad, we are able to gain a richer and more realistic perspective of buyer–supplier relationships. In this study, our goal is to examine supplier–supplier relationships in buyer–supplier–supplier triads, focusing on how such relationships impact the supplier performance. We frame the supplier–supplier relationship as co-opetition—one in which competing suppliers work together to meet the buyer's requirements. We investigate the role of the buyer on such relationships, and how the buyer and co-opetitive supplier–supplier relationships affect supplier performance. We find mixed empirical support for our hypotheses. However, we are able to demonstrate the dynamics of supplier–supplier co-opetition in the buyer–supplier–supplier triad. We point out the need for further studies in this area.     

Supplier Development Practices for Sustainability: A Multi‐Stakeholder Perspective

Supplier development for sustainability is a critical element of sustainable supply chain management and requires extensive multi‐stakeholder collaboration. This article establishes a conceptual four‐stage framework to analyse the collaborative mechanisms of supplier development practices, and presents an exploratory, qualitative analysis to identify the major contributors of sustainable supplier development practices, such as NGOs, industrial associations, consulting firms etc. Based on semi‐structured interviews about 63 organizations from different regions and industries, this article identifies three types of contributor: drivers, facilitators and inspectors. Instead of traditional stakeholder engagement processes, these contributors actively collaborate with buying firms and suppliers to design, implement and evaluate sustainable supplier development programs. The article then provides a matrix to describe the supply chain coverage and supplier performance of supplier development practices, given the absence or positive involvement of facilitators and inspectors. We conclude our study by suggesting future research directions as well as discussing managerial implications. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment     

Online reverse auctions and their role in buyer–supplier relationships

Despite the move in recent years towards supplier partnerships, buying firms need at times to make use of competitive procurement strategies for certain purchases. This study examines the impact of reverse auctions on buyer–supplier relationships through six case studies, analysing primarily the supplier perspective through participant interviews. The authors identify that there are potential benefits for both parties in a reverse auction, which can offer tendering and transactional cost advantages. For buyers, it offers a competitive procurement process. The effect on relationships will depend on the extent to which buyers employ the auction as a price weapon, or whether it is used primarily as a process improvement tool.     

Re-examining the link between fairness and commitment in buyer-supplier relationships

By re-examining the link between fairness and commitment in supply chain relationships, this study elaborates on the existing theory that views fairness only as an antecedent. It proposes that commitment can also precede perceived fairness, thus redefining the link between the concepts as bidirectional in buyer–supplier relationships. The study examines both the buyer and supplier perspectives. Based on interviews at 24 technology industry firms in Finland, this empirical study demonstrates that buyer commitment has a positive impact on how suppliers perceive distributive fairness in the relationship. In turn, this effect is reciprocated by the suppliers through a commitment in the form of relationship-specific investments and continuous improvements that are perceived as fair by the buyer. As a managerial implication the study emphasizes the importance of fairness evaluation to the relationship parties.     

Are relational ties always good for knowledge acquisition? Buyer–supplier exchanges in China

Relational ties between manufacturers and their suppliers serve as an important strategic resource for value creation and realization. However, conflicting evidence exists regarding their role in the acquisition of specific knowledge. This study proposes that relational ties have a nonlinear effect on specific knowledge acquisition and that this nonlinear relationship is conditional on contract specificity and competitive intensity. Results from a sample of 385 manufacturer–supplier exchanges in China demonstrate that a buyer's relational ties with its major supplier have an inverted U-shaped effect on specific knowledge acquisition from this supplier; this inverted U-shaped relationship is stronger (steeper) when contract specificity is high and competition is more intense. These findings suggest that managers should understand the benefits and downsides of relational ties in acquiring specific knowledge and avoid building highly embedded ties when they draft detailed contracts or competition is highly intensive.     

Developing Co-operative Buyer–Supplier Relationships: A Case Study of Toyota

Over recent years many businesses have recognized that there are strong competitive advantages in developing co-operative partnerships with suppliers. An important challenge for many companies is to identify the factors to enable them to move from relationships characterized by strong buyer power and bargaining position, to partnerships based on trust and co-operation. The purpose of this paper is to consider factors that may influence the development of co-operative buyer–supplier relationships. A case study is presented which illustrates the developing relationship between an automotive manufacturer, Toyota Australia, and its suppliers, as part of a new supplier strategy. Several factors are proposed which provide areas for further research. These include the consideration of similarities between the industry and technologies of buyer and suppliers, prior experiences of change among suppliers, effective communications between buyer and suppliers, and the importance of experiential learning in the acceptance of change.     

A pragmatic decision model for inventory management with heterogeneous suppliers

For enterprises, it is imperative that the trade-off between the cost of inventory and risk implications is managed in the most efficient manner. To explore this, we use the common example of a wholesaler operating in an environment where suppliers demonstrate heterogeneous reliability. The wholesaler has partial orders with dual suppliers and uses lateral transshipments. While supplier reliability is a key concern in inventory management, reliable suppliers are more expensive and investment in strategic approaches that improve supplier performance carries a high cost. Here we consider the operational strategy of dual sourcing with reliable and unreliable suppliers and model the total inventory cost where the likely scenario lead-time of the unreliable suppliers extends beyond the scheduling period. We then develop a Customized Integer Programming Optimization Model to determine the optimum size of partial orders with multiple suppliers. In addition to the objective of total cost optimization, this study takes into account the volatility of the cost associated with the uncertainty of an inventory system.     

The impact of supplier dependence on suppliers' CSR: The moderating role of industrial dynamism and corporate transparency

To improve corporate social responsibility (CSR) in the supply chain, focal buyers may use supplier dependence to influence the supplier's resource strategy to promote the supplier's CSR initiatives. Thus, supplier dependence is particularly critical to the supplier's CSR, especially for Chinese suppliers with resource constraints. However, there is limited understanding and research on the degree to which a supplier depends on major buyers for the supplier's CSR from the supplier's perspective. Based on a sample of 284 Chinese listed companies, this study analyses the relationship between supplier dependence and suppliers' CSR through the lens of resource dependence theory (RDT). In addition, we investigate the moderating roles of industrial dynamism and corporate transparency in the relationship between supplier dependence and suppliers' CSR. The results indicate that supplier dependence has a negative impact on the Chinese supplier's CSR performance. Meanwhile, the negative impact of supplier dependence is mitigated for the supplier's more volatile industrial context, while improving corporate transparency enhances the negative impact of supplier dependence. This study verifies the applicability of RDT for the analysis of CSR in the supply chain in emerging markets such as China. Moreover, the study further extends research on the role of buyer-supplier relationships in CSR in the supply chain by extending the research perspective to the supplier side and adding the external and internal uncertainty of the supplier to the theoretical framework for analysis. We also provide managerial implications for implementing Chinese suppliers' CSR from the buyer's and supplier's perspectives.     

Contracting with Private Knowledge of Production Capacity

We analyze the design of procurement contracts when the supplier is privately informed about both his innate production capacity (K) and his innate unit cost of production. We identify conditions under which the supplier will strategically employ an inefficient production technology to expand output above K. We also show that when the buyer employs the simple fixed‐price cost‐reimbursement (FPCR) contracts in the setting examined by Rogerson (2003), the supplier has no incentive to exaggerate K. Furthermore, the buyer can secure with FPCR contracts at least 75% of the surplus she secures with fully optimal contracts.     

Critical success factors for mutual collaboration with suppliers in IT outsourcing industry: a case study of a top IT outsourcing company in Korea

ABSTRACT

Nowadays, information technology (IT) outsourcing companies face enduring demands to reduce cost while increasing productivity. This pressure leads many IT outsourcing companies to rely on outsourcing arrangements with IT personnel suppliers. In order to maximise efficiency, outsourcing companies have focused on fostering high-performing suppliers through improved collaboration and mutual relations. However, it is very difficult to advance to a long-term partnership using the existing outsourcing process because of insufficient collaboration between IT outsourcing companies and their suppliers. Based on collaboration perspective of supply chain management (SCM), this study identifies the critical success factors for collaborative strategic partnerships and presents an evaluation framework for assessing and managing suppliers. We have developed an organisational process model for Supplier relationship management (SRM)-based collaboration which includes some of the key constructs from the previous studies and interviews with the IT outsourcing industry people. In this study, we will identify four types of strategic suppliers and suggest approaches for improving collaborative relationship between an IT outsourcing company and its partner companies. In addition, to validate the feasibility of the proposed model, we applied it to a well-known Korean IT outsourcing company ‘A’.
