Agile and User-Centered Design (UCD) integration allows the advantages of both approaches to be taken in a hybrid method. The requirements will evolve and gradually adapt to the needs of users and customers, and UCD techniques will improve usability and User eXperience (UX) of the developed software. However, there has been much discussion about the challenges of this integration, because of the differing philosophies. User stories and use cases are the typical artifacts for specifying requirements in agile methodologies. On the other hand, prototypes, Persona, scenarios, task analysis and usability testing are UCD techniques, frequently employed in Requirements Engineering. Numerous authors have studied the best way for these techniques and artifacts to be compatible in hybrid methods. However, the different approaches of Agile and UCD make it difficult to jointly apply and manage an agile-UCD project. This article proposes User Objectives for the collection and development of requirements in an agile and user-centered project. The UOs collect the functional and non-functional requirements of the user's wishes. Completing a UO implies the orderly realization of three activities: Specification of Requirements, Presentation and Functionality. This enables, the flexible planning of an order in which to carry out activities, according to agile and UCD criteria. Moreover, the UOs are organized in different categories according to both their development and their relationship with the user. The UOs diagrams enable both the progress of the project to be visualized, thereby facilitating the modularization, prioritization and planning; and also the monitoring of the UOs evaluated with UCD techniques, as well as those that still need to be evaluated. 1
