This degree work was developed with the purpose of designing the Quality Management System based on the NTC ISO 9001:2008 Standard, for the company Vexpro Consultores Ltda., a legally constituted company. The objective was focused on identifying the processes, reaching the creation of the documentation required by the standard and as a final product a quality manual is annexed as a central document and guide. For this purpose, an initial diagnosis was made according to the requirements of the standard and, at the end, an evaluation was made again to verify that the documents that are requirements of the standard are prepared and ready for their application, reaching 90% compliance. The importance and applicability of a QMS for consulting companies is demonstrated, in order to achieve a better internal operation, a better coordination of activities and the provision of a quality service.
