Kirn: proposta de abordagem de evolução tecnológica de sistemas legados

Abstract

In order to keep the institutions' information systems in functional compliance with their organizational processes, there is a need to modernize them frequently. However, difficulties such as the lack of diverse resources (technical, financial, human and others), make this task difficult to perform. In view of the adversities that institutions find in modernizing their legacy systems, this work proposes an approach, defined as Kirn, for the technological evolution of these systems, which has as premise the reengineering of software in an agile way, with efficient use of the available resources aiming the optimization of this practice. To assist in this activity, a tool called Kirn Framework was developed, which helps in mapping the requirements of legacy systems and in creating a base application, which will be the starting point of technological evolution. As a proposal for the evaluation of this approach, an experiment was developed at the Superintendência do Desenvolvimento da Amazônia (SUDAM), using experimental software engineering concepts, in which the prototypes developed with the institutional approach and the Kirn approach were compared through the use of pre-established indicators in the experiment’s planning.
