Abstract The importance of the tourism sector in Colombia has focused on aspects related to competitiveness and sustainability given the impact of tourism activity in the different destinations where it is developed. In order to maintain this advantage, it is essential to strengthen the management of sustainable tourism, optimizing the benefits for users, the destination and the local economy, while minimizing impacts on the environment. In this sense, the governmental demands oriented towards the implementation of these policies in the sector, as indicated by the Sectorial Technical Norms (NTS), specifically, the NTS-TS 002, requires the support of a technological management tool that allows the controlled development of the activities and indicators established by the regulations. Based on this need in the tourism sector, a research project was developed based on the proposal of a management model of the NTS-TS 002 standard, was articulated with a software architecture that later will be specified in a web application to support the diagnostic process, monitoring of the indicators included in the standard and which allow accommodation and lodging establishments to be subsequently certified.
