For the past few years organizations have been enforced to deliver on shorter time, at lower costs and obviously in compliance with all quality requisites. The application of project management tools sets has strongly increased as a response to such demands and the employment of project management offices appears to be the alternative of many organizations. Undeniably, small and medium enterprises play a crucial role in the economy; however, studies with primary emphasis on the use of project management offices in such organizations are rather scarce. The purpose of this master thesis is to evaluate project management offices in small and medium enterprises with the primary objective of identifying their most common functions and responsibilities using prior academic research and a Web-based survey with project management professionals from different countries and industry background.A questionnaire was developed to examine the extent to which small and medium firms utilize project management tools sets and whether or not they adopt project management offices in their structures. Also, it intended to assess to which extent they performed predetermined tasks and whether or not it is dependent on firm size and location. The questionnaire had a total of 188 valid responses from 35 countries from a range of industries.There are three primary findings. The first is that small and medium enterprises are indeed making relevant use of project management offices as 53% of the respondents had such structure in their organizations and 24% mentioned that either a project management office was being implemented or it would be implemented soon in their companies. Secondly, functions related to multi-project management as allocate resources and coordination between projects as well as those associated to strategic management such as management of benefits and compensation, supplying of decision support for stakeholders and the scanning of networking and environment are more frequently found in small and medium than in large enterprises. Finally, project management offices from Australia showed more probability to apply the assessed functions as well as to provide organizational documentation to a greater extent than those from Brazil and New Zealand.
