Individual modes and patterns of rational and intuitive decision-making by purchasing managers

This study extends the literature on decision modes in purchasing. While decision modes have traditionally been divided broadly into rational and intuitive processing modes (dual-process approach), following the tenet of recent psychology research, we further differentiate the latter into experience-based and emotional processing (multiple systems approach). Previous decision-making research has been inconsistent in its findings about the relationship between decision modes and performance. Using the purchasing manager's supplier selection decision process as our unit of analysis, we first investigate the relationship between individual decision modes and the financial and non-financial performance of the selected supplier. Hierarchical regression analyses indicate that rational processing is positively related to both financial and non-financial performance, while emotional processing is negatively related to financial performance, and the interaction of rational and emotional processing is positively related to both performance outcomes. Because recent cognitive psychology assumes that some combination of rationality and intuition is commonly used, we then apply a configuration approach and develop a taxonomy of decision-making modes surrounding supplier selection. Cluster analysis results show five decision-making patterns that are related to the performance of the selected supplier.     

The mediating role of speed in the global sourcing decision process

The principal aim of this study is to provide theory and testing to elucidate the role of decision-maker's decision process and speed during the global sourcing decision-making process (GSDP). In order to achieve this goal, we examine the behavior of a sample of 202 decision-makers belonging to Italian SMEs in the manufacturing sector. Our main finding suggests that faster decisions during the GSDP process lead to superior financial and non-financial performance of the selected supplier. Moreover, we find support for dual processing theory wherein rationality and intuition of the GSDP are associated with increased supplier performance both directly and through their effects on decision speed. Results are discussed in terms of the GSDP, SME and strategic decision-making literatures and practical implications for managers in SMEs.     

The impact of sourcing enterprise system use and work process interdependence on sourcing professionals’ job outcomes

We examine sourcing professionals’ work context to conceptualize how they use sourcing enterprise systems (SESs) and to understand when SES use results in positive/negative job outcomes. We differentiate between SES use for supplier selection and supplier governance, identify sourcing professionals’ work process interdependence as a moderator for the impacts of SES use on job satisfaction, and suggest job satisfaction mediates the impacts of SES use on job performance. We conducted a field study of sourcing professionals’ SES use at one of the largest consumer product companies in the United States, which has implemented an SES to innovate its sourcing professionals’ work processes. Based on our analysis of the survey and qualitative data we collected, we found the impacts of both types of SES use (1) to be negative on job satisfaction when work process interdependence was high, (2) to be positive on job satisfaction when work process interdependence was low, and (3) to be mediated by job satisfaction for job performance. We discuss the implications of our findings for the literature at the intersection of information systems and operations management as well as for the information technology enabled innovation of sourcing processes and, more generally, complex business processes.     

Making tough choices: A policy capturing approach to evaluating the tradeoffs in sustainable supplier development initiatives

This research explores the tradeoffs that decision makers are willing to make when implementing development initiatives to improve supplier sustainability performance. We employ a policy capturing methodology in which respondents are forced to choose between multiple potential sustainable supplier development initiatives. Data were collected from traditional and executive MBA students. The results suggest that when confronted with tradeoffs, decision makers value improvements in supplier cost savings and injury reduction equally, which was somewhat unexpected. Further, both improvements in supplier cost savings and injury reduction were valued over supplier emissions performance. Because we measure individual tradeoff preferences, multi-level regression analysis was used to better understand the impact of respondent value structure regarding sustainably developing suppliers. Our findings suggest a hierarchy of tradeoff preferences for decision makers as they pertain to sustainable supplier development. As the pressure to ensure supply chain sustainability increases, more firms will engage in sustainable supplier development. The outcomes of the choices they make when choosing between initiatives, and how managers make these choices, will be of increasing interest in both industry and academia. This research answers previous calls for further examination of decision maker tradeoff preferences in sustainable supply chain development.     

Supplier development and cost management in Southeast Asia—Results from a field study

This paper is about supplier development when international companies have production sites in Southeast Asia and look for opportunities to switch from international suppliers to local suppliers. We conducted a field study involving site visits to companies in Thailand and Vietnam, and interviews at corporate supply chain departments. Some key observations are: cost management was a dominant motive for taking local supplier development initiatives. Furthermore, local sourcing and local supplier development were important for international companies to improve access to local customer markets. Firms deliberately assessed whether a particular supplier would likely be able to improve sufficiently to warrant investing in supplier development, which typically involved a combination of initiatives, requiring the international firm to take considerable efforts. Local sourcing strategies and priorities for supplier development initiatives tended to focus on items with low supply risk and low volume. These findings are discussed based on transaction cost economics, and we suggest that firms use several ways to reduce the risk of transaction-specific investments in supplier development initiatives.     

Affective diversity and emotional intelligence in cross-functional sourcing teams

In cross-functional sourcing teams, differences in goals and personality traits can lead to tensions and reduced effectiveness. Diversity in teams can be conceptualized as surface-level diversity (e.g., gender, nationality) or as deep-level diversity (e.g., personality, attitudes). This study investigates the potentially negative effects of one category of deep-level diversity – namely, affective trait diversity – on sourcing team performance and how such negative effects might be mitigated through team members' emotional intelligence. The study analyzes a sample of 88 sourcing teams (234 team members) using moderated regression analyses. Sourcing team cohesion is found to fully mediate the relationship between affective diversity and team performance, while the collective emotional intelligence of the sourcing team positively moderates the diversity-cohesion relationship (moderated mediation). Thus, this study provides insights into both the mechanics of team diversity and the critical role of collective emotional intelligence in sourcing teams and thereby enables supply managers to better understand cross-functional team setups and effectiveness.     

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.     

Practice and promise of formal supplier selection: a study of four empirical cases

In this paper an experimental study of formal decision-making models for supplier selection is described. Attention is paid to all phases of the supplier selection process: the recognition of the need for a new supplier, the formulation of decision criteria, the qualification of suitable candidates and final selection. It appears from the experiments that formal decision models may prove to be useful in various ways throughout the whole supplier selection process and in different purchasing situations.     

Choosing between single and multiple sourcing based on supplier default risk: A real options approach

The selection of a given purchasing strategy is a central activity in risky environments. Single sourcing, a powerful approach in a stable environment, can amplify a firm's exposure to risk (e.g., supplier's default) in the presence of uncertainty. Multiple sourcing, however, presents higher costs due to the management of more than one supplier. A correct evaluation from a risk management perspective is needed. This paper proposes the Real Options approach for valuing the probabilistic benefits of multiple sourcing in managing the supplier default risk (to be compared with the related higher costs). A computational model, based on the Monte Carlo simulation, was developed. The results show the (probabilistic) advantages of adopting the multiple sourcing strategy in risky environments for a specific case. The proposed sensitivity analysis is aimed at identifying the impact of the most important transactional parameters on the differential benefits of the two sourcing strategies. Thus, the model and its managerial implications represent a valid support for the decision-making process in the presence of uncertainty.     

Narcissism and Empowerment: How Narcissism Influences the Trickle-Down Effects of Organizational Empowerment Climate on Performance

The present study proposes a trickle-down model of employee empowerment in which empowerment climate at the organization level is positively related to the empowering leadership of team leaders and ultimately to individual task performance. Importantly, we hypothesize that team leaders’ and members’ narcissism can respectively inhibit and enable the cross-level empowerment process by affecting the intended distribution of decision-making authority and resources between team leaders and members. The analysis of data from 834 team members of 189 teams in 46 organizations reveals that organizational empowerment climate is positively related to team leaders’ empowering leadership when they are less narcissistic. Empowering leadership is positively related to individual task performance when team members are highly narcissistic. Finally, we observe that the combination of less narcissistic leaders and more narcissistic members is a condition under which the indirect effect of organizational empowerment climate on individual task performance through empowering leadership is positive.     

Evaluation of supplier capability and performance: A method for supply base reduction

Development of partnership with suppliers is widely recognised today as a potent tool for supply chain improvement. To develop an effective partnership, it is necessary to have a small supply base and an effort to reduce the supply base to a manageable level. Despite its overwhelming importance, models of supply base reduction are rare. Supplier sorting methods, used for pre-selection of suppliers and sometimes seen as methods for supply base reduction, have limitations ranging from (1) requirement of an exhaustive database of historical information (case-based reasoning), (2) inability to predefine the number of elements in a cluster (cluster analysis) and (3) inability to identify suppliers who are both highly capable as well as high performers (data envelopment analysis). In the present work, we develop a systematic framework for carrying out the supply base reduction process. The study assumes two important dimensions of suppliers—performance and capability. Performance of a supplier represents short-term effects on the achievement of supply chain objectives while supplier capability indicates long-term effects. Many of the performance and capability factors are imprecise in nature. In order to account for the imprecision involved in numerous subjective characteristics of suppliers, we use fuzzy set approach to measure the imprecision of these factors and rank a potential list of suppliers against their performance and capability. We then display their ranks in a ‘capability–performance matrix’ that helps a decision maker arrange the suppliers in decreasing order of preference. The desired numbers of suppliers are finally selected on the basis of this ordered list. The suggested framework will be of immense help to the practising managers in reducing the supply base—a prerequisite for building a strong supplier partnership and developing an effective supply chain.     

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.     

Low power,high ambitions: New ventures developing their first supply chains

This paper investigates sourcing decisions for new ventures. Sourcing decisions are especially problematic for start-ups because they lack resources, knowledge and legitimacy to evaluate and interact with suppliers. We develop and apply a framework that connects global sourcing, relationship development and attractiveness. Further, we investigate how new ventures develop their first supply chains by conducting an exploratory multiple case study of six Norwegian start-ups. Based on our findings, we develop three propositions regarding how start-ups mediate their lack of attractiveness through pre-sales and by choosing shorter supply chains and smaller suppliers. The implications for practice include emphasizing the importance of developing a business relationship with the supplier in parallel with making sourcing decisions. This study is a novel contribution to an underexplored topic, and we conclude by proposing a research agenda for future explorations of start-ups and supply chain development.     

Low cost country sourcing and its effects on the total cost of ownership structure for a medical devices manufacturer

In this paper, we describe a total cost of ownership (TCO) method as an activity-based costing (ABC) application along the value chain to measure and analyse the costs of international sourcing activities. We further describe the method's implementation for a manufacturer of high-tech medical devices. For this case study, we analyse the effects of shifting purchasing volume from traditional procurement market suppliers to low cost country suppliers on the cost structure of purchasing projects. We find that particularly costs at component and supplier level gain importance over traditionally dominating unit level costs. Furthermore, we identify low cost country sourcing as a decision with extensive impact on value chain entities other than purchasing. Finally, a considerable part of costs in low cost country sourcing accrue at the beginning of a purchasing project due to problems stemming from unsatisfactory initial quality, language barriers and intercultural communication.     

Sole sourcing,competitive sourcing,parallel sourcing: Mechanisms for supplier performance

Quality management practitioners in the USA such as W. Edwards Deming, strongly advocate the Japanese model of supplier relationships-recommending substantial specific investment in a single supplier for improved co-ordination and higher quality. But the strategy literature and conventional wisdom favor multiple sourcing, suggesting that a high level of specific investment in a sole source will lead to problems with supplier performance. Using agency theory, we construct a model to evaluate the tradeoff between the costs to set up and coordinate with suppliers and the incentive for performance provided by competition. We find that the validity of Deming's Point Four, that sole sourcing is more profitable than competitive sourcing, depends on parameters such as profit sensitivity to supplier performance.     

Co-alignment of supplier quality management practices and cognitive maps – A neo-configurational perspective

Much of the previous research on the ‘purchasing practice–performance link’ rests on the notion of “net effects,” which assumes that specific practices independently of each other impact outcomes. This study challenges this core tenet by adopting a neo-configurational perspective, exploring how different combinations of factors (called “configurations”) affect outcomes. Another limitation of extant studies on the ‘purchasing practice–performance link’ is the narrow focus on practices; more recent behavioral supply management research finds the behavior of managers to be critically influenced by cognitive maps—the lenses through which managers perceive, simplify, and interpret the world. Focusing on supplier quality as a core aspect of the broader ‘purchasing practice–performance link’, this study explores how configurations of different supplier quality management (SQM) practices and SQM-related cognitive maps help firms to manage supplier quality. It uses fuzzy-set qualitative comparative analysis (fsQCA) to identify SQM configurations and a cognitive-linguistic approach for the computerized text analysis of purchasing managers’ cognitive maps in the context of Western companies sourcing from Chinese suppliers. The configurational fsQCA analysis identifies four different configurations associated with overcoming barriers to SQM in emerging markets. SQM-related cognitive maps prove to be a critical component in these four configurations.     

Impact of relational norms, supplier development and trust on supplier performance

Supplier relationship management and supplier development initiatives assume a fundamental role in enterprise supply chain management. An important aspect of effective supplier relationship management is the role of trust. This paper seeks to understand whether supplier relationship management or supplier development initiative should be emphasized as a firm strives to achieve superior supplier performance. The analysis and discussion draws upon sourcing strategy literature and is based on empirical survey-data of mid to upper level managers with responsibility for supply management initiatives in their respective organizations in Denmark and in the USA. It examines the interrelationships among “relational norms”, “trust”, “supplier development initiatives” and ensuing “supplier performance”. The data analysis shows that firms must emphasize relation and trust building activities before investing in supplier development initiative. Supplier perception audits must be routinely performed to gauge the level of trust and strength of relational norms.     

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.     

What is required for greener supplier selection? A literature review and conceptual model development

This paper examines the existing literature on green supplier selection. In total, 60 articles are reviewed, all published in peer-reviewed journals between 1991 and 2011. The articles are analyzed in terms of several general variables such as type of research and theoretical viewpoint, as well as more specific variables such as the supply chain position considered, stages of the supplier selection process studied, and the perspective taken on environmental criteria. The main findings are threefold. First, analytical research, focusing on developing normative decision models for the final stage in green supplier selection is clearly most dominant, employing a wide range of techniques. Second, empirical research is less prominent and generally lacks a clear theoretical background. Third, very little conceptual research has been done linking green supplier selection to an organization's strategy. Research on green supplier selection is highly fragmented and in danger of overemphasizing the technical aspects of supplier selection. Based on this review of the articles, a conceptual model of green supplier selection is presented, aimed at integrating the different dimensions of green supplier selection and identifying directions for future research.     

Vertical FDI versus outsourcing: The role of technology transfer costs

The effect of technology transfer cost on the choice between horizontal foreign direct investment (FDI) and licensing is well established. We explore this “make or buy” decision in the offshoring context when offshore input production involves costly technology transfer. The burden of technology transfer cost that falls on the sourcing firm depends not only on the technological complexity of the offshored input but also on the mode of organizing offshoring. Outsourcing entails low technology transmission cost but a higher distortion in input production by the arm's length supplier while vertical FDI involves a higher technology transmission cost but a lower distortion in input production by the affiliated supplier. Contrary to the existing literature, we find that, irrespective of the type of good, outsourcing is the preferred mode at higher ends of technological complexity.
