Fatores de sucesso e insucesso na implementação de sistemas de informação gerencial: estudo do caso do segmento de exploração e produção de petróleo da Petrobrás S/A

Abstract

Recent studies indicate the existence of an information systems paradox: even the conceptually perfects, many become notorious implementation failures. This study has as main objective, understand the factors that contribute for successful or unsuccessful management information systems. Previous studies identified four main constructos that seem to be related with the success of these systems: (1) complexity, (2) user participation, (3) management support, (4) development team. Thus, we empirically test them existence thru the case study of exploitation and production segment of Petrobras -Petróleo Brasileiro S.A. management information system. The results indicate that the variables have power to explain system failure, indicating also management support and complexity as main causes and; that the adoption of this kind of system must be preceded of more formal evaluation.

Increasing the satisfaction with the Integrated System for Academic Activity Management: prioritizing improvements with a structural equations model

“…First, the performance of information systems was evaluated by engineering-related technical parameters such as processing speed, time savings, and output quality (Ferreira & Bufoni, 2006). The following models were then created to assess how well the system met the users' needs.…”

“…As a result, several models were developed and tested, and a variety of quantitative instruments were employed to determine the dimensions that best reflected these variables (Choe, 1996). First, the performance of information systems was evaluated by engineering-related technical parameters such as processing speed, time savings, and output quality (Ferreira & Bufoni, 2006). The following models were then created to assess how well the system met the users' needs.…”

Gestão Estratégica De Custos: Uma Intervenção Aplicada a Um Posto De Combustível

“…O contexto em que as organizações se inserem está cada vez mais dinâmico e hostil, sendo que, esse dinamismo está associado às mudanças de tecnologias de materiais, processos e produtos, à internacionalização, bem como, à abertura dos limites geográficos ao comércio e investimentos, proporcionando novas oportunidades às empresas e acarretando na crescente competitividade (LAUSCHNER;BEUREN, 2004;FERREIRA;BUFONI, 2006).…”
