Through the longitudinal case study approach, this paper aims to present and analyze the evolutionary change of the procedure and performance of a technology-based company Project Management Office (PMO). The study has exploratory character and focuses on understanding the factors that motivated the transitions occurring in the PMO over 13 years of experience. To this end, information was raised on the functions performed by the PMO during this period, as well as its relations with managers and project teams, functional managers and senior management. Representative performance data about projects and PMO are presented. It was found that experienced tensions are the main drivers of change, which are determined by the functions and results shown by the office. The study allowed the construction of a framework to explain the transitions that reach PMO, which can be used to conduct more comprehensive studies in more descriptive character.
