Application of statistical analysis to improve time management of a process modeling project

Abstract This work was the result of a cooperation agreement between the University of Brasilia (UnB) and a security organization. Its goal was to model the logistic processes of the company to assist in the modernization of a control system for the management of materials. The project was managed in a dynamic model, through the monitoring and control of activities executed during its various stages. The development of a control system enabled the detection of discrepancies between what was planned and how it was performed, identifying its causes and which actions to take to ensure that the project got back on track according to the planned schedule and budget. The main objective of this article was to identify which elements controlled by the project affected its execution time. With that knowledge, it was possible to improve the planning of the next phases of the project. To this end, we performed a case study of exploratory aspect and quantitative nature to provide information on the object and guide the formulation of hypotheses. The qualitative analysis of the execution time of the modeling identified two dependent variables - systematic version and team - out of the four evaluated. The quantitative analysis studied two variables - number of modifications and number of elements -, which did not indicate evidence of correlation with the aforementioned time. Resumo Este trabalho decorreu de um termo de cooperação firmado entre a Universidade de Brasília (UnB) e uma organização de segurança, cujo objetivo foi o mapeamento de seus processos logísticos, realizado com o intuito de amparar a modernização de um sistema de controle gerencial de materiais. O projeto foi gerenciado num formato dinâmico, mediante o monitoramento e controle das atividades executadas no decorrer de suas diversas fases. Foi desenvolvido um sistema de controle que permitiu encontrar as discrepâncias entre o planejado e o realizado, identificar as suas causas e agir para que o projeto retornasse ao seu curso no prazo e nos valores planejados. Este artigo teve como principal objetivo identificar quais os elementos controlados pelo projeto impactaram em seu tempo de realização para a melhoria no planejamento das fases seguintes do projeto. Neste sentido, foi realizado um estudo de caso de cunho exploratório e natureza quantitativa com o objetivo de oferecer informações sobre o objeto e orientar a formulação de hipóteses. As análises qualitativas identificaram a dependência de duas variá
