In the first semester of 2015, a project was developed with the department of medicine dispensation of a midsize city from São Paulo. The project had for objective mapping a process and its optimization, utilizing Industrial Engineering concepts. A diagnosis following the steps of DMAIC methodology was done. After mapping process and task analysis, the project consisted in a time study, leading to the utilization of 2-sample t hypothesis test utilizing Minitab software. From the diagnosis recommendations were made for process improvement in medicine dispensation.
