- A Dinâmica da Reconfiguração no Modelo Agile/Virtual Enterprise – um factor determinante no alinhamento estratégico com o mercadoPublication . Cunha, Maria Manuela; Putnik, Goran; Ávila, PauloVários factores determinam actualmente o desempenho dos novos modelos organizacionais, dos quais se destaca a capacidade de as organizações alcançarem e explorarem vantagens competitivas em sinergia usando ou integrando o “melhor” conjunto de recursos que em cada momento se lhe oferecer para cada uma das funções que a organização realiza, capacidade essa que caracteriza as empresas virtuais. A necessidade de manter o alinhamento permanente com o ambiente de mercado em permanente alteração, exige da empresa virtual a capacidade de reconfigurar a sua estrutura organizacional de forma extremamente rápida, ajustando-se de forma dinâmica ao mercado. Vários modelos têm sido propostos destacando-se no presente artigo o modelo Agile/Virtual Enterprise (A/V E), que é aquele onde a importância da dinâmica da reconfigurabilidade assume um aspecto crítico. Contudo, o modelo A/V E apenas faz sentido se forem garantidas condições para a sua rápida reconfigurabilidade. A implementação e plena exploração do modelo A/V E exige, assim: (1) a capacidade de acesso aos fornecedores de recursos que reunam potencial para desempenhar da forma ideal, as funções para que possam ser seleccionados, (2) a possibilidade de realizar as funções de projecto da A/V E, negociação entre os potenciais candidatos para integração e de gestão da A/V E independentemente da distância e (3) a minimização do tempo de integração e de reconfiguração. Estas características apenas coexistem no ambiente proposto pelos autores, designado Mercado de Recursos.
- Market of resources for virtual enterprise integrationPublication . Cunha, Maria Manuela; Putnik, Goran; Ávila, PauloMost 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; Camarinha-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 profit from a specific market opportunity, and where each participant contributes with its best practices and core competencies to the success and competitiveness of the structure as a whole. Even during the operation phase of the VE, the configuration can change, to assure business alignment with the market demands, traduced by the identification of reconfiguration opportunities and continuous readjustment or reconfiguration of the VE network, to meet unexpected situations or to keep permanent competitiveness and maximum performance (Cunha & Putnik, 2002, 2005a, 2005b).
- Taxonomy of broker's functions in virtual enterprisesPublication . Ávila, Paulo; Putnik, Goran; Cunha, Maria Manuela; Pires, AntónioNot just with the emergence but also with the growing of the electronic market, that is, the growth of online suppliers of services and products and Internet users (potential consumers), the necessary conditions to the affirmation of the agile/virtual enterprises (A/VE) as a present and future enterprise organizational model are created. In this context, it is our understanding that the broker may have an important role in its development, namely, if the broker performs functions for the A/VE with better efficacy and efficiency. In this article, we will present first a revision of the broker’s models in a structured form. We present a taxonomy of possible broker’s functions for the broker’s actuation near the A/VE and then the classification of the literature broker’s models. This classification will permit an analysis of a broker’s model and establish a mainframe for our broker’s model according to the BM_Virtual Enterprise Architecture Reference Model (BM_VEARM).
