UM MODELO DE PROCESSO PARA ESTRUTURAÇÃO DO ANTEPROJETO DE SISTEMAS DE INFORMAÇÃO: UMA APLICAÇÃO NA PREFEITURA MUNICIPAL DE SALVADOR

Abstract

Software engineering aims at the systematic production of proposing software development models, methods and techniques for implementing the various stages of its production, in order to offer products and services that meet the quality required by the user and their needs. From this context we realized the importance of using standards such as standards and models that specify requirements and best practices for getting a quality product through the process of software development. However, in many cases, it is identified that systems ill-suited problems resulted from the definition of non-functional requirements, which were not considered or elicited appropriately. The omission of these requirements does not imply the identification of needs and particularities of the business in relation to the objectives, policies and cultures of the public sector, resulting in systems that do not meet your expectations. However, there is a lack of methodologies and processes for identifying organizational requirements for the preparation of the draft systems to assist in the decision to start a software project. This paper presents a model to guide the lifting of the necessary requirements to support the decision on the initiation of systems projects, which must be implemented in the public sector, with emphasis on non-functional requirements in the preliminary phase of the information systems. The proposed model has implications for the system alignment with strategic business objectives, assist in the preparation of documentation and reference contribute to the process of software development with relevant information. This paper presents a model to guide the lifting of the requirements for the decision support systems on projects that should be implemented in the public sector, with emphasis on non-functional requirements. This model was subjected to a proof of concept trial and a subsequent application, which can be verified its effectiveness. Seeks to identify the alignment of the proposed system with strategic business objectives, assist in the preparation of documentation and reference contribute to the process of software development with relevant information. In the application of the proposed model for the preliminary phase of the information systems, there has been an increase in quality in the following aspects: ease in storage and recovery requirements; reuse of requirements demands systems that involve the same organ; better tracking requirements in instances of changes, better identification of risks of failure of systems or business involved.
