Resumen
The development of web applications is an increasing demand. A variety of technological tools, processes and methodologies have been developed in order to optimize the time and effort required to develop such applications. In this work I am going to focus on agile methodologies where every year more organizations and start-ups bet on this revolutionary technique, improving traditional rigid processes. This thesis it is intended to develop a web application through the integration of Lean UX and SCRUM, where development can be optimized by applying both methodologies. The Lean UX process consists of building, measuring, and learning; in the case of SCRUM the process consists of developing iteratively and incrementally new functionality in what is known as sprints. The duration of each sprint is fixed in time, but the number of user stories (functionalities) can be adapted according to the duration of the sprint and the speed of the team. The development of this project has been conducted in a real environment and is based on solving the needs of a real client by applying Lean UX and Scrum using the tool JIRA. This master's thesis explains the integration of both approximations in JIRA and the kind of adaptations and elements that were used to represent the Lean UX and SCRUM artefacts in the tool.
