Requirements traceability is an important quality factor in the life cycle of the software, there is a lot of software standards that demands his implementation, for example, ISO/IEC 29110, a standard for very small entities; however, projects of small organizations do not perform an adequate application of traceability. In the literature there are proposals with a high level of abstraction; the realization of a traceability information model for small software development organizations provides a narrow alternative, reducing the gap between the theory and the reality in software development. We present a traceability information model for small organizations within the framework of ISO/IEC 29110, in this way organizations access an illustrative and reusable traceability solution that allows them to improve the quality of software development. The article contemplates the definition of the models. © 2018 Copyright is held by the owner/author(s).
