Com este novo modelo e com o avan?o da internet, surge, o conceito eERP (Extended Enterprise Resources Planning Planejamento de Recursos do Empreendimento Estendido), tratando-se ent?o da nova era do ERP, uma nova realidade de colabora??o entre as empresas, em que se extrapolam as suas barreiras e consegue-se um melhor controle dos neg?cios. A transforma??o do ERP em eERP n?o muda a fundamenta??o que o ERP deva ter, mas implementa a conectividade que o modelo de e-business tem. O presente estudo, atrav?s de pesquisa bibliogr?fica, completada com um estudo de caso, fornece uma vis?o ampla de que a exist?ncia precedente de aplica??es ERP s?lidas ? o fator preponderante para se ter solu??es de ebusiness coerentes e integradas ao ERP.
