Putnik University of Minho, Portugal E INTRODUCTION Most definitions of virtual enterprise (VE) incorporate the idea of extended and collaborative outsourcing to suppliers and subcontractors in order to achieve a competitive response to market demands (Webster, Sugden, & Tayles, 2004). As suggested by several authors (Browne & Zhang, 1999; Byrne, 1993; Ca- marinha-Matos & Afsarmanesh, 1999; Cunha, Putnik, & Ávila, 2000; Davidow & Malone, 1992; Preiss, Goldman, & Nagel, 1996), a VE consists of a network of independent enterprises (resources providers) with reconfiguration capability in useful time, permanently aligned with the market requirements, created to take solutions for VE integration are either inexistent or insufficient. Therefore, there is a need for further effort by the community towards satisfactory and competi- tive solutions. In the article, we introduce some of the most recent developments and environments to cope with the VE requirements, such as the electronic marketplaces, in- cluding the recent generation of collaborative electronic marketplaces, breeding environments, virtual clusters, and so forth, and present the market of resources as a tool for managing, controlling, and enabling network- ing and dynamics in VE integration.
