Abstract-Small companies have the potential to be agile, flexible and informal because they are usually formed by few members. This usually creates more synergy among these professionals because they tend to have more than a single role inside the company. With such role versatility, it is understandable that those professionals have to multitask/split their working hours among different kinds of demands: that may cause difficulties in planning, development, verification and improvement of internal processes. This article brings a case study where the COBIT 5.0 toolkit (Process Assessment Model) was used to identify internal processes that needed improvement within the studied company. In order to improve the selected processes, ABNT NBR ISO/IEC 12207 was tailored concerning the company's needs. Additionally, it was applied the PDCA cycle of continuous improvement and it was also proposed the adoption of an agile method, SCRUM, to integrate internal activities and processes.
