Recent advances in supply chain management information systems (SCM IS) have enabled firms to more fully collaborate with their supply chain partners — driving out costs while increasing responsiveness to market demands. This chapter examines various types of SCM IS — from traditional EDI systems to more recent Web-services-based e-business applications. It argues that the approach best suited for an organization depends in part on the degree of integration between the partners, the complexity of the business processes, and the number of partners involved. A model is presented for analyzing the costs and benefits that can be expected from each type of SCM IS. The model enables researchers and practitioners to better understand the differences among SCM IS and thus can help reduce the risks of implementing these valuable yet complex information systems.

Legacy information systems can be a serious headache for companies because, on the one hand, these systems cannot be thrown away since they store a lot of valuable business knowledge over time, and on the other hand, they cannot be maintained easily at an acceptable cost. For many years, reengineering has been a solution to this problem because it facilitates the reuse of the software artifacts and knowledge embedded in the system. However, reengineering often fails due to the fact that it carries out non-standardized and ad hoc processes. Currently, software modernization, and particularly ADM (Architecture-Driven Modernization), standardized by the OMG, is proving to be an important solution to that problem, since ADM advocates carrying out reengineering processes taking into account the principles and standards of model-driven development. This chapter provides an overview of ADM and shows how it allows legacy information systems to evolve, making them more agile, preserving the embedded business knowledge, and reducing maintenance costs. Also, this chapter presents the software archeology process using ADM and some ADM success stories.

In this article certain pillars as basics are presented being necessary to develop Web services (W3C, 2007) supporting human resource (HR) processes like assessing, hiring, modeling information systems, staffing, and so forth; by the help of these Web services. Current HR information systems in general do not adequately support tasks related to cross-organizational or global skills and competence management. In the following, the topic is presented which relates to knowledge management especially to “communities of practice,” as well as related topics such as e-skills and ICT (information and communication technologies) professionalism; the latter currently being broadly discussed by experts in Europe. HR managers of a company or an organization are challenged through the need to formalize skills requirements and to continuously monitor the skills demand inside the company. Obtaining ICT skills are not a one-time event. Technological change advances at a high speed and requires that skills need continually to be kept up-to-date and relevant (The European e-Skills Forum [ESF], 2005). During the last years, new concepts have emerged which intend to empower learners and individuals to steer learning processes to a large extent on their own. Learning objectives tend to be increasingly individual in character (ESF, 2005). In this context, providing an appropriate infrastructure which supports the continuing professional development (CPD) of employees is today a key issue.CPD processes require a respective infrastructure encompasses besides qualifications, skills/competence frameworks and body of knowledge, as well required standards for competence, skills, and appropriate career and development services. Standards encompass educational and industry-oriented performance standards which in turn are expressed preferably through a common language as competence and skills standards. The governance and administration of the CPD process require the availability of flexible and personalized certification services which offer the formal validation of individuals’ learning achievements independent of where and how they were acquired.

Distributed information systems are growing rapidly in response to the improvement of computer hardware and software and this is matched by the evolution of the technologies involved. This article focuses mainly on Web Services technology and discusses related technical issues including availability, performance and composition. It also introduces Grid, agents and Semantic Web technologies that can work together with Web Services to serve different business goals.
