The role of joint collaboration planning actions in a demand‐driven supply chain

Purpose – Drawing on the operations and information systems literature as well as concepts tied to buyer‐seller relationships, the objective of this exploratory research is to measure the influence of joint collaboration planning actions on the strength of relationships, interorganizational information systems (IOISs) use and firm flexibility. The path model proposed in this study also posits that joint collaboration planning actions and the strength of relationships positively affect IOISs use, which in turn positively affects firm flexibility.Design/methodology/approach – Empirical evidence is gathered through an electronic survey conducted with 53 suppliers in a single supply network in the telecommunications equipment industry.Findings – The present study demonstrates that joint collaboration planning actions positively and significantly impact the strength of relationships. The results also show that IOISs use mediates the impact of joint collaboration planning actions and of the strength of relation...

Determinants of the future level of use of electronic marketplaces: The case of Canadian firms

Based on the literature dealing with the diffusion of innovation and with information systems, and building on the emerging concepts in electronic commerce (e-commerce), this paper aims at assessing the influence of various factors on firms’ future level of use of electronic marketplaces (e-marketplaces). This theoretical model is tested on data collected from 1,200 senior managers in Canadian firms. Findings indicate that a firm’s past experience in e-commerce, as well as the factors relating to its business relationships ultimately affect its future use of e-marketplaces. Results of TOBIT regressions also show that the complexity of sophisticated e-commerce implementations is negatively correlated with the future level of use of e-marketplaces, and that consultants and other experts play an essential role in encouraging and facilitating the use of this new type of electronic platform. Finally, our survey data demonstrate that the relative influence of some determinants differs according to the firms’ size.

Safeguarding mechanisms in a supply chain network

Purpose – Building on the transaction cost theory and power structure literature, this paper aims to investigate the extent to which firms use two safeguarding mechanisms (supply chain relational investments and electronic collaboration) in different network dependency contexts in order to protect their portfolios of business relationships.Design/methodology/approach – Empirical evidence is gathered though a survey data conducted with 159 firms in the wireless communication sector. The paper tests the assumption that the two safeguarding mechanisms are used to a greater extent in interdependency‐intensive networks than in other supply chain contexts.Findings – This empirical study suggests that: in a network‐dependent context, relational investments allow firms to safeguard their portfolios of relationships; electronic collaboration seems to be a safeguarding mechanism for firms in downstream‐dependent network contexts; in general, firms appear to use both relational investments and electronic collaborati...

Minimum sample size estimation in PLS-SEM: The inverse square root and gamma-exponential methods

Partial least squares‐based structural equation modelling (PLS‐SEM) is extensively used in the field of information systems, as well as in many other fields where multivariate statistical methods are used. One of the most fundamental issues in PLS‐SEM is that of minimum sample size estimation. The ‘10‐times rule’ has been a favourite because of its simplicity of application, even though it tends to yield imprecise estimates. We propose two related methods, based on mathematical equations, as alternatives for minimum sample size estimation in PLS‐SEM: the inverse square root method, and the gamma‐exponential method. Based on three Monte Carlo experiments, we demonstrate that both methods are fairly accurate. The inverse square root method is particularly attractive in terms of its simplicity of application.

Joint collaborative planning as a governance mechanism to strengthen the chain of IT value co-creation

Drawing on the relational view of the firm, this paper examines the chain of IT-based co-creation of value and how joint collaborative planning between partners can strengthen this chain. Using data from51suppliers in the telecommunication equipment industry, our analysis demonstrates that the greater the partner-specific IT investments made by the firm, the greater its use of supply chain collaborative systems (SCCSs) with those partners and the greater the firm uses SCCSs with partners, the greater its benefits, through the generation of relational rents. Further investigation also shows that partner-specific IT investments is not a predictor of firm benefits and hence confirms the hypothesized chain of IT-based co-creation where IT investments encourage IT use, which in turn creates business value. Finally, our findings also show that joint collaborative planning between partners is an important governance mechanism, anchored on control and trust, that can strengthen the relationship between SCCSs use and firm benefits by impacting the other sources of relational rents tied to the use of SCCSs. This contribution should give academics and practitioners alike a better understanding of how both SCCSs and joint collaborative planning can foster the co-creation of value.

Electronic commerce and supply chain integration: the case of the telecommunication equipment industry

Purpose – This paper presents an analysis of the impact of electronic commerce on firms in the telecommunications equipment industry.Design/methodology/approach – Using the OECDs value chain methodology, electronic commerce initiatives identified in the optical connectivity value chain were analyzed for each of the four layers of the chain, namely network operators, system integrators, assemblers and sub‐assemblers.Findings – The findings from our case studies indicate that electronic commerce initiatives primarily influence process and relational innovations through supply chain collaboration. The real benefits of electronic commerce come from end‐to‐end visibility in the supply chain, and from the implementation of demand‐pull strategies for all levels of the optical connectivity equipment value chain.Research limitations/implications – Future research should concentrate on the impact of various emerging electronic marketplaces in demand‐driven integrated supply chains.Originality/value – Results revea...

The Role of Collaboration on Process, Relational, and Product Innovations in a Supply Chain

This article focuses on the impact of strategic and tactical collaborative actions as well as e-collaboration tools efficiency on process and relational innovations, which in turn should influence product innovations. The results of this study show that tactical collaborative actions, rather than strategic actions, are more geared towards leading firms to innovate. Findings also suggest that relational innovation has an effect on product innovation for the upstream perspective, while process innovation influences product innovation for the downstream perspective.

Determinants of Manufacturing Firms' Intent to Use Web Based Systems to Share Inventory Information with their Key Suppliers

Based on the literature on the diffusion of innovations and on information systems, and building on emerging concepts in electronic collaboration (e-collaboration), this article measures the influence of various determinants on manufacturing firms’ intent to use Web-based inter-organizational information systems (IOISs) to share inventory information with their key suppliers. This theoretical model is tested on data collected from 498 senior managers of Canadian manufacturing firms. Our findings indicate that a manufacturing firm’s organizational readiness, its past experience with e-commerce and its business relationships all affect its future use of Web-based IOISs to share inventory information with its key suppliers. The results of Tobit regressions also provide supporting evidence that firm size moderates the impact of the present use of e-commerce with suppliers on manufacturing firms’ intent to use Web-based IOISs to share inventory information with key suppliers.

Collaborative e-product development and product innovation in a demand-driven network: the moderating role of eCRM

Customer relationships, product development, data integration and demand-driven supply chains are key concepts for companies that wish to remain competitive in today’s global economy. To address this important information management issue, the present study examines how, within a demand-driven network context, an eCRM can influence the interorganizational product development process between a manufacturer and its key customers. The theoretical model, built on research related to a technology assimilation model based on Fichman’s (2000) work, was tested on data from 104 manufacturers in the wireless equipment sector. The results show that the adoption of an eCRM does not moderate the relationship between collaborative e-product development involving a manufacturer and its key customers and product innovation within the manufacturer itself. Moderated regression analyses also demonstrate that, among the manufacturers that have adopted an eCRM, the impact of collaborative e-product development by the manufacturer and its key customers on product innovation within the company will be stronger when investments in the eCRM implementation, internal integration of the eCRM, and eCRM usage are higher than lower. Finally, the findings show that investments in the eCRM implementation, internal integration of eCRM and eCRM usage are also antecedents of product innovation within the manufacturer. This contribution, at the intersection of the CRM and product development research streams, should give academics and practitioners alike a better understanding of the role of eCRMs in the product development process.
