Toward Evidence-Based Integration of Information Architecture in Agile Development. Lecture Notes in Computer Science, 16715, 205-219. https://doi.org/10.1007/978-3-032-31407-9_130302-97431611-3349https://hdl.handle.net/20.500.12740/24907Information Architecture (IA) is critical to the success of interactive systems, but integrating it into agile and User-Centered Design (UCD) environments poses challenges because there are few tools that automate the transition from conceptual analysis to software development. This paper presents Scrum-UIA-MAT, a web tool designed to systematize the Scrum-UIA methodology. The tool aligns user and business needs through three fundamental axes: 1) the systematic integration of contextual research into Product Backlog management; 2) dynamic prioritization of requirements formally based on usability, IA, and business value; and 3) automatic recommendation of agile IA techniques during Sprint execution. To validate the proposal, a quasi-experimental study was conducted with 16 software engineers following the ISO-9241-11 standard. The results demonstrate 100% effectiveness in performing critical tasks and satisfaction levels exceeding 83%. The dimensions of utility and ease of use also surpassed the 80% threshold, with excellent internal consistency (Cronbach's Alpha = 0.96). The study confirms that Scrum-UIA-MAT is an effective solution for centralizing design information and reducing cognitive load in project management, fostering a robust integration of IA into agile processes. This contribution provides both a methodological framework and technical instrumentation to improve the quality of modern software systems.http://purl.org/coar/access_right/c_14cbInformation ArchitectureScrumUser-Centered DesignCASE ToolsUsabilityAgile Project ManagementBook Chapterhttps://doi.org/10.1007/978-3-032-31407-9_13
