The influence of product life cycle on the efficacy of purchasing practices

WHY AND HOW TO INVOLVE PURCHASING IN NEW PRODUCT DEVELOPMENT?

In new product development (NPD) firms increasingly have to rely on external expertise from suppliers. However, results of early supplier integration have been found to be ambiguous. This research empirically tests the hypothesis that the participation of professional purchasing agents early on in the supplier integration process plays a decisive role to distinguish successful projects. Our sample gave evidence that early supply management integration positively moderated supplier involvement’s effect on firm success. Hence, firms may benefit from avoiding supplier integration without professional purchasing management. Still, in many firms the procurement department is not yet integrated in NPD processes early on. Our research identifies four measures those firms applied, in which purchasing got fully embedded in the innovation process: top-management support, structural differentiation, explicit processes, and a collaborative corporate culture. This finding can serve as blue print for implementing purchasing integration and therewith improve the success of supplier integration in NPD.

Performance analysis of supplier development programs

Purpose

The purpose of this paper is to provide an approach that a manufacturer can periodically use to measure the performances of its supplier development programs (SDPs). It also quantifies and indicates the specific supplier development outcomes (SDOs) that a manufacturer has to concentrate in improving its SDPs.

Design/methodology/approach

The proposed methodology integrates fuzzy analytic hierarchy process (to determine the importance of SDOs), Pareto analysis (to choose the significant SDOs) and fuzzy logic (to periodically determine the performance indices and grades of the SDPs) methods to measure the performances of SDPs. In order to demonstrate the utility of the methodology, a case situation is presented where the performance measures of SDPs running at five key suppliers of an Indian turbine manufacturing company were determined.

Findings

By periodically applying the above mentioned methodology, the performance indices of a manufacturer’s SDPs are measured, monitored and managed effectively. It is shown that the methodology is advantageous in clearly indicating the scope of improvement for the SDPs along the specific SDOs.

Research limitations/implications

Since the obtained results in this study are specific to a manufacturing environment, they may not be generalized. However, the generic lists of SDOs mentioned in the paper and the proposed approach can be used in any manufacturing environment for analyzing the performances of SDPs.

Practical implications

The performance analysis of SDPs would help a manufacturer to know more about the functioning of its SDPs along the timeline and provide the scope for improvement.

Originality/value

The proposed approach successfully measures and also grades the performances of SDPs. The results enable the supplier development managers to effectively distribute their investments and efforts along the SDPs.

Improving retail supply flexibility using buyer-supplier relational capabilities

Purpose

The purpose of this paper is to investigate the mediating role of three important relational capabilities – absorptive capacity (AC), transactive memory systems (TMS), and organisational interoperability (OI); on the flexibility of buyer-supplier relationships and performance in retail supply chains. Drawing on the relational view of strategic management, the impact of relational capabilities on two forms of supply chain flexibility is examined – configuration flexibility (CF) for switching suppliers with minimal penalties, and planning and control flexibility (PCF) for altering supply schedules, quality, and delivery lead-time.

Design/methodology/approach

Strategic- and tactical-level managers from 211 retail stores in the UK were surveyed. The authors validated a measurement model with structural equation modelling and tested four hypotheses on the mediating role of relational capabilities on supply chain flexibility and retail performance, controlling for size, duration of relationship, and market segment.

Findings

Results showed that the three relational capabilities partially mediated the positive effect of CF and PCF on operational performance in big middle and niche retailers. Examining the interaction effect of the forms of flexibility on the relational capabilities and performance, the authors found positive interaction effects on TMS and OI but a non-significant effect on AC.

Practical implications

In addition to providing novel theoretical insights on supply chain flexibility, the findings have practical implications for supplier selection and buyer-supplier relationship management.

Originality/value

Overall, the study highlights the impacts of relational capabilities on adopted operational strategies such as flexibility, buyer-supplier relationships, and retail performance.
