It becomes partly crucial for the organization to be in the dynamics of the sector and market where it operates and wants its consolidation, because value systems become strategic elemente that play a role as key factors of success in organizations seeking priority intend to increase their organizational performance. Given the above, this research seeks to get to identify strategic uses of information and communication technologies in the processes of the value chain in small commercial businesses in Mexicali, aiming to contribute to the improvement of the competitiveness of the same. It is in this sense that the technologies of information and communication have become a powerful tool that will allow them to be innovative, cost-effective and this will have an impact on the performance of the organization that will allow you to improve your service, interact with customers and suppliers, and above all more efficiently meet their own needs and organizational expectations. This research was exploratory and within the relevant findings, coming to the conclusion that it is necessary to focus more emphatically on the client; organizations have deficiencies in relation to the strategic use of ICTs to streamline their billing, manufacturing, distribution, and storage of your products, activities highlighting this if they don＇t have a reconsideration in this aspect, at the risk of offset in terms of its competitors which would mean ceasing to be option on the market, stressing that this not only will be a trigger factor in mature companies, but those who need to improve their service and that they will serve as input for the conduction of processes along the value chain. The research is exploratory in nature, as evidenced in the use of the ICTs focused on the man~,gement of the value chain and its relationship with different variables of such management, making that they are discovered behaviors on the structure of the value chain able to generate sustainable benefits and contribute to the improvement of the competitive position of the companies involved in this study.展开更多
