Micro, small and medium-sized software development enterprises are one of the most representative sectors of the global economy. For this reason, obtaining concrete results in the actual context through the methods and models proposed to support software quality is an important contribution to the field of the software industry. In this sense, this paper presents the application of the models proposed by Competisoft (an Iberoamerican project focused on increasing the competitiveness of small enterprises through the process improvement strategy), in order to drive the improvement of some software processes into five Colombian small and medium-sized software development companies. Additionally, this paper also shows the behavior of the application of Competisoft from two approaches: (i) determine, for a company, how productive is adoption of this improvement strategy, in terms of effort and progress, and (ii) refine, validate, and improve models of Competisoft based on the results in reports of experience.
