With customer-relationship management (CRM) no longer a buzzword among trendsetters, organizations in all types of industries initially rushed to embrace it. Although a seductively attractive concept, the implementation of CRM proved difficult, however, and organizations are struggling with realizing their vision of a CRM organization. To help managers assessing the stage of relationships between their organization and the organization's business customers we consider the automotive industry. Based upon our case organization and its relationships with numerous business customers we develop a practical tool to question, identify, and prioritize critical aspects of customer-relationship management. First, we identify key areas in CRM. Secondly, we investigate how the chosen case organization has managed each of these key CRM areas over a broad range of business-customer relationships. Thirdly, we acknowledge that many organizations simultaneously have different types (transaction-relationship continuum) of business customers. We finish the article with a discussion of the study's limitations, and suggest avenues for future research. 相似文献

The success of a vehicle on the market depends on its price, reliability, and attractiveness; for the latter, innovations are the key elements in the differentiation from competitors. Managing the processes of selecting and integrating innovation projects into vehicle projects is therefore crucial. This article presents a management tool that aims at managing the interplay between innovation projects and vehicle projects. The objectives are to increase and optimize the amount and value of innovation projects integrated into vehicle projects. The tool, called “Profilor,” is based on the concept of intrusiveness, which is presented from a theoretical and empirical point of view. 相似文献

This article presents an approach to integrating life cycle assessment (LCA) into an activity-based costing (ABC) model to develop a steering system that takes into account both financial costs and associated environmental impacts. By combining the formalism of LCA and ABC matrix calculations, we show how impact assessment results can be affiliated with costs to jointly and simultaneously compute the costs and environmental impacts of products and activities. The conditions of integration are developed following the four-step structure of LCA. The proposal is applied to a simplified case study of the ‘Classic Pen Company.’ The developed ABC-LCA approach paves the way for further test applications, which are considered useful in the context of environmental indicators for strategic steering, communication with customers and forecasting or simulation. 相似文献
