Purchasing practices in small- to medium-sized enterprises: An examination of strategic purchasing adoption,supplier evaluation and supplier capabilities

The benefits that can be derived from effective purchasing have long been recognised in the management literature. Despite a growing body of research on purchasing practices in small- to medium-sized enterprises (SMEs), a number of key issues remain under-examined. We investigate SME purchasing practices in terms of (1) the degree to which purchasing is regarded as a ‘strategic’ activity by SMEs, (2) the use of supplier evaluation systems by SMEs and (3) the supplier capabilities emphasised by SME buyers. Through a survey of UK SME managers, we find that purchasing practices varied greatly across SMEs. Purchasing formality is generally low with limited evidence of purchasing being employed strategically and with many firms not undertaking formal supplier evaluations. In terms of supplier capabilities, we find that SMEs differ in the capabilities they prioritise, with three distinct groups evident. These groups are labelled ‘holistic’, ‘process’ and ‘logistics’ based on the supplier capabilities they emphasise. These three groups of firms also differed in terms of the emphasis they placed on strategic purchasing, supplier evaluation, technological focus and how they compete in their main markets, but not in terms of firm size or number of suppliers utilised. The implications of these findings are discussed and areas meriting future research are proposed.     

Purchasing involvement in technologically uncertain new product development projects: Challenges and implications

This paper explores an emerging field of research within purchasing that concerns the changing role of purchasing when companies embark on technologically uncertain NPD projects. Where existing research has examined the role of purchasing in facilitating early supplier involvement in new product development, little research has been done to date on how purchasing's role might change when facing technologically uncertain NPD that require new capabilities and new technology. Based on an in-depth case study of a technologically uncertain NPD project in the passenger ship rescue equipment industry, the paper sheds light on how supplier involvement in NPD projects with a high degree of technological uncertainty impacts on a company's sourcing strategies and the challenges this poses for purchasing.Based on the case study findings, we propose a) that early purchasing involvement in technologically uncertain NPD projects requires a mature purchasing organization that possesses competences to interact effectively with R&D and b) that involving a new supplier from a different industry in NPD projects characterized by technological uncertainty requires a leap of faith from both innovating firm and supplier. The paper contributes to research in early supplier involvement in new product development, in particular the thin branch within this body of literature that now focuses on early purchasing involvement.     

Drivers of green supply management performance: Evidence from Germany

Five potential drivers of green supply management performance were identified in the literature review: green supply management capabilities, the strategic level of the purchasing department, the level of environmental commitment, the degree of green supplier assessment, and the degree of green collaboration with suppliers. These constructs were used to form a structural model explaining the environmental performance and the purchasing performance. The model was analysed with SmartPLS 2.0 using data collected among German purchasers. The results suggest that the degree of green supplier assessment and the level of green collaboration exert direct influence on environmental performance. These two practices are driven by the strategic level of the purchasing department and the level of environmental commitment of the firm. Whereas commitment influences green assessment directly, the impact of commitment on green collaboration is mediated by the capabilities of the purchasing department. Furthermore, the results show that environmental performance has a positive impact on purchasing performance.

A knowledge sharing framework for black,grey and white box supplier configurations in new product development

Managing supplier collaboration is increasingly cited as a key success factor in new product development (NPD) performance. Knowledge sharing between customer and supplier is a critical issue to manage collaboration but one which has only been partially investigated in the inter-organisational NPD context. This means that the specific characteristics of knowledge sharing according to the three classical supplier involvement configurations (black box: design is supplier driver, grey box: joint design and white box: design is customer driven) are still largely unknown. This research proposes to fill this gap by presenting a conceptual framework for knowledge sharing according to the supplier involvement configuration. Knowledge sharing integrates knowledge transfer, translation and transformation. A qualitative methodology based on cross-case comparisons of six projects in two companies is used. This research shows that the dynamics of knowledge sharing depend on each configuration. Thus, for black box projects, knowledge translation is a prerequisite for knowledge transfer. For grey box projects, knowledge transfer and translation are initiated simultaneously in a continuous loop. For white box projects, knowledge transfer is the key activity and potentially generates knowledge translation. The results suggest that managers should pay attention to translation activities which are critical for the success of co-development projects.     

The effects of low internal integration between purchasing and operations on suppliers’ resource mobilization

A company that suffers from low internal integration between corporate functions performs worse than its more integrated competitors, leaving it in a position of competitive disparity. This paper reports on an investigation of the effects of internal integration between purchasing and operations on the mobilization of supplier resources. Low internal integration generates uncoordinated operations and purchasing behaviors that negatively affect supplier resource mobilization. We find that the lack of operations support for eight major purchasing initiatives in a construction company negatively affects supplier resource mobilization, resulting in poor exchange outcomes for the suppliers. Furthermore, different types of uncoordinated behaviors affect suppliers’ resource mobilization in diverse negative ways. Based on the results, we offer a categorization of diverse types of supplier mobilization activities and offer several managerial implications for both buyers and suppliers.

A contingency-configurational view of purchasing operations: The mediating role between supplier relationship and firm performance

The literature has considered purchasing and supply management activities from a strategic perspective, but the tactical role of purchasing operations has yet to be explored. Purchasing operations represent the internal modus operandi for transactions with suppliers, comprising three main activities – purchasing transactions, purchasing document management, and purchasing assessment – and supportive activities like purchasing knowledge management. Following the contingency theory, we hypothesize that these internal activities mediate between external supplier relationship management and firm performance (financial, customer and delivery performance). Complementarily, we adopt the configurational theory to hypothesize that this link between external and internal activities can be combined to increase firm performance. To test this contingency-configurational view of purchasing operations, we conducted a quantitative survey with 234 companies. The regression results of the contingency analysis show that purchasing operations activities have a full mediation role in most relationships between supplier relationship management and firm performance, while knowledge management positively moderates the association between purchasing assessment and customer performance. Moreover, the cluster analysis for the configurational analysis shows that supplier relationship management and purchasing operations follow maturity levels of joint implementation of internal and external activities. Our findings shed light on the purchasing operations by defining the activities representing this concept and showing their role in supply management. We also contribute to practice by proposing an integrative system that helps managers organize the firm's purchasing and supply management activities.
