Alberto de Medeiros; Gilberto Perez; Sergio Lex

The choice of an Enterprise Resource Planning (ERP) must be made judiciously by the high costs involved in the acquisition of such systems. Managers in areas such as accounting, financial and information technology need support and tools that help in selecting an appropriate ERP for their business. With this article, we present a study aimed at investigating the possibility of a Decision Support System (DSS) to be used for this selection interrelating evaluation criteria, which could allow to contemplate the strategic alignment between Business and Information Technology. From the literature review 28 factors related to the selection of software packages, with special emphasis on ERP were identified. For the research procedures, the qualitative ones were adopted, in that the 18 factors considered relevant to a good selection of ERP were classified with the Delphi technique and used as input in a DSS: Analytical Network Process (ANP), applied as a Case Study in a small business that hired the ERP. The results showed that the ANP was efficient in interrelated criteria and evaluated the strategic alignment between Business and Information Technology.

Moisés Ari Zilber; Gilberto Perez; Sergio Lex

Varios estudos indicam que inovacoes levam a competitividade. Baseado nessa justificativa, este trabalho procurou entender as relacoes entre inovacao tecnologica e competitividade presentes na industria de equipamentos eletro-medicos e determinar quais os possiveis fatores que influenciam essas relacoes. Realizaram-se duas pesquisas de campo com metodologias de pesquisa de natureza qualitativa e exploratoria: a primeira baseada na tecnica de Grounded Theory e a segunda, na analise de conteudo. As analises dos dados da primeira pesquisa apontaram as evidencias de uma teoria que relaciona a importância da inovacao na cadeia produtiva como meio de conquistar competitividade. A segunda pesquisa identificou os seguintes fatores que exercem influencia sobre essa relacao: estrategias empregadas para inovar; condicoes ambientais externas favoraveis a inovacao; estimulos geradores de inovacao e influencia das condicoes internas sobre a geracao de inovacao. Estes fatores convergem para a obtencao dos beneficios esperados pelos fabricantes para a inovacao, que, por sua vez, evolui para a obtencao de vantagens competitivas. O estudo mostrou que e viavel a hipotese de que os fabricantes se apoiam em inovacoes tecnologicas para conquistarem vantagens competitivas.
