RESUMO

The construction of a software involves high degree of risk and requires of the manager a lot of planning to attend the budget estimates and meet deadlines. In the context of software processes, there are limited technological resources that allow the extract of knowledge of the processes modeled in PSEEs and indicate what factors cause the greatest impact on the final result, providing new opportunities to improve management. To overcome these deficiencies, is possible to use simulation to obtain information about the activities of the process and sensitivity analysis to identify the variables that most significantly influence the results. Thus, this work proposes a simulation model, integrated to a tool that support project management centered processes, which uses data from the base of the PSEE, offers resources to handle the process data in a deterministic or stochastic way (simulation), allows the testing of various scenarios and enables the analysis of which variables most significantly impact the final result (sensitivity analysis), before starting the execution of activities. The simulation model development was based on the knowledge gained with a systematic review of the papers on simulation in recent years and a comparative evaluation of technological resources offered by the tools identified in the selected papers in the review. The results obtained with the implementation of the proposed model, using the information in a real case study, modeled on WebAPSEE, provided information that indicates improvements in relation to the cost and time development of the process under study, as well as the identification of the variable with the greatest sensitivity, allowing to optimize the performance of these activities.
