Modelo de sistematização de uso de ferramentas para desenvolvimento de sistemas informatizados em empresas de pequeno porte

Abstract

Development of computer based systems should be an organized task involving participation of the user. Along its development it must generate documents that guide the developer on creation of the system project. It could originate a system that takes care of the user expectation, in an economical way and with acceptable quality. The existing methodologies for system development are based on CASE tools, most of them are automated and they are very costly. It is causing partial or total abandonment of its use by developers linked to small companies. This dissertation presents a systematization model of tools applied to development of computer based systems. It uses as basis the incremental life cycle model associated with a prototype model. By filling the considered forms in a sequential way and developing the necessary diagrams in a manual way, the developer is led towards execution of development tasks for computer based systems. Using a case study, where the proposed model was applied to development of computer based systems, it is possible to conclude that the created system is of a high quality one, low cost in its development and higher productivity of the involved professionals.
