Le renforcement du rôle des filiales dans la stratégie d'innovation de la Firme Multinationale (FMN) est souligné par différents travaux. Nous proposons quatre idéaux types différenciés de la contributions des filiales dans cette stratégie à partir d'un cadre analytique qui prolonge celui de Bartlett et Ghoshal (1989) et de l'étude du cas d'une FMN emblématique. Parallèlement aux " grandes historiques " et aux "implémenteurs", deux nouveaux types sont mis en avant; les " accélérateurs" et les "forts potentiels" qui développent des innovations susceptibles d'être déployées dans le reste de la FMN. Le type d'innovations que chaque type de filiale serait le plus à même de développer est également précisé.

In industries characterised by strong uncertainties on demand, supply chain collaboration has been considered an important factor to improve performance, but remains difficult to implement. Drawing on a comparative case study of the relationships between a Japanese manufacturer and three French retailers in the digital still camera industry, we delineate a series of contingent factors that determine the conditions under which supply chain collaboration with retailers can be effective. We propose the concept of adaptive collaboration, contingent on the product life cycle and retail partners' attributes, to determine the fit between product strategy and supply chain processes. We show how it can help solve some of the issues associated with the development of collaboration and help improve a company's supply chain performance

Social mobilization is a process that enlists a large number of people to achieve a goal within a limited time, especially through the use of social media. There is increasing interest in understanding the factors that affect the speed of social mobilization. Based on the Langley Knights competition data set, we analyzed the differences in mobilization speed between users of Facebook and e-mail. We include other factors that may influence mobilization speed (gender, age, timing, and homophily of information source) in our model as control variables in order to isolate the effect of such factors. We show that, in this experiment, although more people used e-mail to recruit, the mobilization speed of Facebook users was faster than that of those that used e-mail. We were also able to measure and show that the mobilization speed for Facebook users was on average seven times faster compared to e-mail before controlling for other factors. After controlling for other factors, we show that Facebook users were 1.84 times more likely to register compared to e-mail users in the next period if they have not done so at any point in time. This finding could provide useful insights for future social mobilization efforts.

Context-aware recommendation has become increasingly important and popular in recent years when users are immersed in enormous music contents and have difficulty to make their choices. User emotion, as one of the most important contexts, has the potential to improve music recommendation, but has not yet been fully explored due to the great difficulty of emotion acquisition. This article utilizes users’ microblogs to extracttheir emotions at different granularity levels and during different time windows. The approach then correlates three elements: user, music and the user’s emotion when he/she is listening to the music piece. Based on the associations extracted from a data set crawled from a Chinese Twitter service, we develop several emotion-aware methods to perform music recommendation. We conduct a series of experiments and show that the proposed solution proves that considering user emotional context can indeed improve recommendation performance in terms of hit rate, precision, recall, and F1 score

Global organization of innovation processes

In this article, we first present a brief over-view of the historical evolution of global innovation in multinational firms. We then outline four components and challenges facing firms that are evolving towards global innovation. Next, we focus on the beginning and end phases of the innovation process: their inception and their diffusion. We show that the stakes related to inception tend to sustain internationalization but induce ever more complex innovation diffusion. In the conclusion, we present open issues and questions that merit further attention and research by the academic community working at the intersection of innovation management and international management.

To sustain its competitive position as the leader in providing information solutions to the oil and gas industry, Schlumberger transitioned to a cutting-edge product-platform software architecture by embedding a leading geological modeling software product—Petrel—within Ocean, its collaborative open software platform. The practices it used to overcome the challenges of the transition give rise to three principles that can be leveraged by other companies

Impacts of adaptive collaboration on demand forecasting accuracy of different product categories throughout the product life cycle

Mots clés : Supply chain collaboration, Supply chain strategy, Demand forecasting accuracy

This paper aims to empirically analyze how adaptive collaboration in supply chain management impacts demand forecast accuracy in short life-cycle products, depending on collaboration intensity, product life-cycle stage, retailer type and product category.Design/methodology/approach – The authors assembled a data set of forecasts and sales of 169 still-camera models, made by the same manufacturer and sold by three different retailers in France over five years. Collaboration intensity, coded by collaborative planning forecasting and replenishment level, was used to analyze the main effects and specific interaction effects of all variables using ANOVA and ordered feature evaluation analysis (OFEA).Findings – The findings lend empirical support to the long-standing assumption that supply chain collaboration intensity increases demand forecast accuracy and that product maturation also increases forecast accuracy even in short life-cycle products. Furthermore, the findings show that it is particularly the lack of collaboration that causes negative effects on forecast accuracy, while positive interaction effects are only found for life cycle stage and product category.Practical implications – Investment in adaptive supply chain collaboration is shown to increase demand forecast accuracy. However, the choice of collaboration intensity should account for life cycle stage, retailer type and product category.Originality/value – This paper provides empirical support for the adaptive collaboration concept, exploring not only the actual benefits but also the way it is achieved in the context of innovative products with short life cycles. The authors used a real-world data set and pushed its statistical analysis to a new level of detail using OFEA

Purpose– The purpose of this paper is to identify the four principles for firms in developing countries to enhance and augment their innovation agenda for staying competitive. With increasing globalization, firms need to continually calibrate and realign their innovation strategies to remain competitive. Although many firms in the developed countries are making sustained efforts to adopt the developing world perspective on innovation, similar efforts by firms in developing countries to reorient their innovation strategies to the developed world are minimal. In the long run, this might erode the competitiveness of firms in developing countries. Leveraging the global innovation strategy framework, the paper suggests four principles that can help developing country firms transition from a local to a global innovation strategy. Specifically, the paper exhorts developing country firms to move from a “good-enough” innovation approach to an “augmented” innovation philosophy that aims to serve the latent needs of the users. The four principles suggested for the developing country firms to further their innovation agenda are: invest in research; learn to fail; be patient; and alliance and acquire.Design/methodology/approach– The paper uses prior literature and frameworks to identify the four principles that firms in developing countries should follow for furthering their innovation agenda with a view to becoming global in their approach.Findings– The four principles suggested for the developing country firms to further their innovation agenda are: invest in research; learn to fail; be patient; and alliance and acquire.Originality/value– The paper identifies the four principles for firms in developing countries to enhance and augment their innovation agenda for staying competitive.

Leading Collaboration in Online Communities

Despite the growing importance of online communities in creating knowledge and facilitating collaboration, there has been limited research examining the role of leaders in such settings. In this paper, we propose a framework that integrates behavioral and structural approaches to explore the antecedents of leadership in online communities focused on knowledge work. Specifically, we propose that sociability and knowledge contribution behaviors as well as structural social capital lead to being identified as a leader by members of the online community. We test this framework using social network, survey, and message-level content analysis data collected from three different online communities focused on technical topics. The results from our zero inflated negative binomial models, with 6,709 messages from 976 individuals, provide strong support for the framework that is developed in this study. Our study contributes to both theory and practice by identifying the behavioral and structural antecedents of leadership in online communities

Information systems success and failure are among the most prominent streams in IS research. Explanations of why some IS fulfill their expectations, whereas others fail, arecomplex and multi-factorial. Despite the efforts to understand the underlying factors, the IS failure rate remains stubbornly high. A Panel session was held at the IFIP Working Group 8.6 conference in Bangalore in 2013 which forms the subject of this Special Issue. Its aim was to reflect on the need for new perspectives and research directions, to provide insights and further guidance for managers on factors enabling IS successand avoiding IS failure. Several key issues emerged, such as the need to study problems from multiple perspectives, to move beyond narrow considerations of the IT artifact, and to venture into underexplored organizational contexts, such as the public sector
