Sistemas de Apoio à Decisão:

The present article aimed to analyze the main factors the impacting the software development systems in the Brasilia Aeronautical Computer Center – CCA BR, in order to the necessity in develop the decision-making systems (SAD). The study was made under an analytic approach and was motivated by the following factors: the Aeronautical Command System Rule (NSCA 7-6) which assign to the CCA BR specifics lines of direction to provide any solutions that can support the High Direction decisions; the current CCA BR‘s software process model was developed in view of the ordinary decisions and not to the SAD. The research was conducted by the literature review with the qualitative methodology approach. Initially were described the main aspects related with software engineering emphasizing the development process. Afterwards were commented the main model features of Rational Unified Process (RUP) and were presented a conceiting view about the information systems, pointing out the SAD. Finally in light of the concepts, the main factors were identified and described in the process phase’s analysis‘ pattern in order to the new kind of software features adaptation. Was concluded that the SAD development using the RUP model is possible, once some methodology adjustment can be done, mainly at the part related to the requirements identification and the database technology.
